Customer Ratings & Reviews

I have slept great since purchasing these and have used them every day since. Im a side sleeper and they fit comfortably and I haven’t had them fall out or cause any discomfort while sleeping. The first night they disconnected from my phone twice. I since turned off the wifi feature on my phone and they haven’t disconnected again. I also switched to sleep mode so not sure which of these two changes stopped the disconnection issue. The batteries have lasted at least 8 hours which is what i have slept. I work nights and sleep during the day. I have two dogs and dont hear a thing.

Good headphones, i can play music before sleeping, and it automatically switches over to sleep mode (white noise) once it has detected ive fallen asleep. The sleep tracker on the app is very insightful. The only con is the battery life.. they barely make it 7 hours before dying. Would only recommend as long as you are aware of the battery life.

This is definitely a good earbuds to have. I used to play mobile game and watch video in bed before falling asleep. The quality of the sound is good for games and video, and it will change to white noise after I fall asleep. This product provide such a good experience. And the duration of battery is also good. no need to charge every day.

I've been wanting to find a pair of earbuds that would work well for sleeping for awhile now, so I was excited to give these a shot. I've used a variety of true wireless earbuds over the past couple of years, and my current favorite are just too big to be comfortable. Let's start with fit. These are the smallest true wireless earbuds I've ever used. They fit very well, and there are a variety of silicone tips and "wings" included, so there'll likely be one that works great for you. The box includes the earbuds, their charging case and a USB-C cable for charging. The cable is pretty standard, nothing notable here. The case is a sort of pearl white, and holds enough juice for seven charges, according to Anker. It takes about two hours for a full charge, which will last 6 hours in Music mode and 10 hours in sleep mode at 50% volume. I'm not sure if that's entirely accurate, but I've had plenty of charge left on the earbuds after wearing them to bed (my volume is set to around 30%). The charger face slides open smoothly with a satisfying click as the magnets lock it into position. Oh, and If part of the reason you're looking at these is because someone sleeping next to you doesn't want to hear what you want to hear, I can tell you that even outside of your ear, they're inaudible at less than a foot away at 50% volume. Audio quality is good, especially for something I'm primarily wearing to bed. It doesn't match my other earbuds, but it's fine for sleep. Most of the time I'm listening to an audiobook or something with the volume fairly low. It did seem to struggle pretty hard with quality above 50% volume until I went into the Soundcore app and started playing with the equalizer. Even the built in presets dramatically improved the sound. It's also important to make sure you've got a good fit. The app is unintuitive. It starts off strong, immediately attempting to pair the earbuds and walking you through some basics, but it quickly goes downhill. The Discovery and Profile tabs seem more interested in trying to sell me sunglasses than providing me with functionality, and I had to hunt around to try to figure out how to use it. I did manage to stumble across the equalizer, which you're going to need, and the white noise function, which is impressively customizable. Want to listen to dogs barking and ducks quacking in the rain? Anker's got you covered. There's also an alarm function inside of the sleep mode if you want to make sure it stops playing white noise and wakes you up. Unfortunately, if you really wanted to fall asleep listening to dogs barking and ducks quacking in the rain, you're going to have to do it outside of sleep mode. This means the alarm function won't work, and it won't track your sleep patterns. Not a huge deal for me, because I track my sleep with another device, but if that's something you're looking forward to, know that the only things you can listen to in sleep mode are one of Anker's 30ish presets. You can't listen to music, podcasts, audiobooks, your custom DogDuckRain white noise profile, or anything else with sleep mode turned on. Overall, the earbuds are very comfortable for sleeping. I'm a side sleeper and while I did initially fear that one was going to fall out during the night, so far they haven't. There's no way I could smash one of my other earbuds into a pillow and be able to fall asleep, so that alone makes these worth it for me, I just won't be using the Soundcore app for anything other than the equalizer. I recommend this if you're looking for small earbuds with good audio quality to wear to bed and aren't expecting to use them for much more than that.

Very good quality for regular headphone use, as well as sleep!!

Worked great, but die quickly. Purchased in April and initially worked out pretty good. (Less then 7 months old) They do tend to pop out in the middle of the night which i can live with. But running out of power after 4-5 hours in unacceptable for sleep pods...

Since the beginning I have trouble to connect it to my phone, and after less then two months they stop working. I don’t recommend.

The sleep buds are great, I really like when they change to sleep mode automatically

_____ *Pros: -Very small and light. -Feels very comfortable in ear and doesn’t hurt. -A good library of noise-masking sound effects. -The sound is crisp and clear. -Good battery life. -Love having an alarm that goes off inside my ear. _____ *Neutral: -Cannot view sleep data without first pairing the sleep buds to the app. _____ *Cons: -Once the sleep buds are added to the app, you can’t go back and change the sleep bud volume or toggle Adaptive Noise Masking. -When I wake up, I find the noise-masking sound to have stopped playing. These Anker Soundcore Sleep Earbuds are my third set of noise-masking sleep buds I’ve tried, and I have mixed feelings about them. On one hand, I like how small and light they are, and how comfortably they fit inside my ears without hurting them. Usually, sleeping on my side will cause pain and discomfort but these Anker ones are the most comfortable ones yet. I also like the charging case and the way the sleep buds align themselves perfectly without me having to rotate them or reposition them before charging can begin. The Bose Sleep Buds 1 was really bad at this so I’m glad Anker sidestepped this issue. Connectivity and control with the Anker Soundcore smartphone app was another positive – the sleep buds were added quickly and never lost connection when I was upgrading the firmware, browsing the sound library, or setting my alarm. The layout of the app is clean, intuitive, and easy to navigate. There are a whole bunch of sound files to choose from and my favorite sound for falling and staying asleep is Water. The audio is crisp and clear, and it felt immersive. Now, onto some negatives. The biggest annoyance for me was that after adding the sleep buds into the app, I could no longer go into the Sleep Mode tab to change the volume level or toggle on and off the Adaptive Noise Masking feature. The moment I tap on the Sleep Mode tab, the earbuds begin to play my chosen sound file and the buds become automatically disconnected from my phone’s Bluetooth. Pressing the volume buttons on my phone didn’t have any effect. This was infuriating because in order to raise the volume higher, I had to reset the sleep buds, wide the data from the Soundcore app, then start the initial pairing process all over from the beginning. So, if you don’t get the volume level right the first time during setup, then you’ll have to go through the setup process all over again. It’s a horrible design. The second negative is that the sound file stops playing the audio after a certain time and I don’t know when that happens. Every time I woke up, the sleep buds were silent and not making any sounds regardless of whether I had set an alarm or not. Fortunately, the alarm always went off, meaning it isn’t a battery life issue. My sleep buds already had one firmware update waiting for me when I first paired them with my phone. I’m hoping Anker will release more updates in the near future to correct these issues I’ve encountered. If the sleep buds didn’t behave like this, then I would’ve been so much happier. Unfortunately, the competition for the Anker sleep buds out there is not much better. I’ve tried both the first and second-generation sleep buds from a big audio company, and both of them crapped out in about a year. Until Anker releases updates the sleep buds and fixes the issues I’ve been having, I cannot rate these higher than 3 Stars. There is some potential but these aren’t that great as of now.

I use a CPAP machine for sleep apnea & the exhaust from the face mask often wakes me up after 2-4 hours of sleep. Given their description, I thought these buds would be ideal for helping me relax with some BT music of my own & then provide some appropriate white noise or other background sound to help obscure that intrusive whooshing so I could continue to get as much quality sleep as possible. In the end, my results with the Sleep A10s were a bit mixed; as such, I would have a hard time giving them a hands-down recommendation unless you find the price or size as compared to any alternatives particularly compelling. Starting with the design, these are some of the smallest & lightest true wireless buds I've EVER used--the fact that they manage to produce some surprisingly decent sound from an enclosure this small is remarkable. The Sleep A10s are what I would consider just a bit "thick" at the low end--not bass-heavy or bloated, but they do offer very pleasing performance in the lower registers that helps give music or complex video soundtracks (BT A/V delay was virtually unnoticeable, BTW) just a bit of heft, enough so that I gladly used them for casual BT listening on my iPhone & Steam Deck. However, un-EQ'd mids did seem a bit recessed & hollow; highs also lacked some of the razor's edge clarity & "sparkle" you might get from higher-quality buds. Granted, audiophile music quality is not really the point here, nor do these offer support for any high-res codecs like aptX-HD or LDAC. Nevertheless, I was able to dial in the sound more to my liking using one of the 22 (!!!) EQ presets available in the Soundcore companion app; or you could create your own preset using the 8-band custom EQ. I suspect that other than *not* catering to any ultra-rabid bass-heads out there (because you're simply not going to get any visceral, gut-punch-style bass performance out of sleep-oriented buds that are *this* tiny), there's bound to be an EQ setting in here that gets you more than pleasant results for causal/leisure BT listening beyond just getting your brain ready for sleep. Those tiny buds & their low profile supposedly make the A10s better suited for side-sleepers; I tepidly agree. I have about half a dozen other true wireless buds at home & all of them are too large to wear comfortably in bed if I roll over onto my side. As the anatomy of my outer ear is somewhat shallow, I found the A10s ALMOST comfortable enough to wear while side sleeping, but eventually the gentle pressure of the pillow pushing the bud into my ear canal forced me to roll back over & remove at least one of them. Fortunately, I spend most of my time asleep on my back because of the CPAP...and in that position, these buds are positively dreamy (no pun intended). While already small in construction, Soundcore offers 3 sizes of ear wings & 4 sizes of silicone tips to help get you a good, comfortable, & sound-blocking seal. Whether asleep on my back or just using them while I was up & about, the A10s are about the most comfortable true wireless buds I've ever used--and the first buds I've EVER tried that did not leave my ears feeling sore & fatigued after wearing them all night long. Okay, that covers sound & comfort which are the two factors that always make or break any buds I try & ultimately decide to pass or keep, but these are a bit different as their primary purpose is for sleep-related functionality. So...what’s the verdict here? To start, be sure you know that these buds are NOT noise-cancelling; they are not going to make you feel like you're sleeping in a dead-silent anechoic sound chamber. They offer passive noise blocking via the in-ear seal & noise masking by whatever sounds happen to be pumping through the buds as you drift off to sleep. As such, I could still make out the hum of the fan near my bedside, a faint bit of wind noise escaping from my CPAP mask, & at least awareness of the fact that my wife was sometimes talking to me in bed (though in fairness, I could not make out a single word she was saying until I took one bud out to hear clearly again). In that respect, the buds do greatly attenuate ambient noise to help you sleep more soundly, but they do not eliminate it entirely--unless you happen to crank up the BT audio or sleep-aid sounds in the buds themselves, but then good luck falling asleep with the volume so high! The lion's share of the remaining sleep-oriented functionality relies on the companion Soundcore app, & here is where things started to falter just a bit. Like any good "smart" sleep aid, you can monitor the quality of your sleep throughout the night--but only so long as you start the Soundcore app on your phone before going to bed; otherwise, your sleep patterns will not be recorded by the buds & then synced to your phone later. My sleep state recordings seemed hit-or-miss. Some nights I would have a record of my entire sleep cycle (the app even captured the 3-hours I used them later in the day during one of my medical treatments), but other nights the app/buds only managed to get about 1-2 hours of sleep data on record despite me leaving the buds in (and being asleep) for several hours as verified by the sleep counter on my CPAP machine. The app also features something called "Smart Volume Control" which supposedly adjusts the volume of the cycling sleep sounds according to the level of ambient/external noise measured by your smartphone's mic. However, I had to turn the volume of the sleep mode WAY up just to hear the selected sleep sound (my favorite was simply blowing winds) at all, & if I left the Smart Volume Control enabled, I couldn't hear anything from the buds when I would wake up in the middle of the night. The Soundcore app is also a bit confusing in terms of the A10's two operational modes of use. In "Music Mode," you can listen to any BT music/audio source on your phone, but it's also the mode where you select from one of the 30 or so "Sleep Mode" soundbite songs (birds, wind, water, static white noise, musical instruments, etc.) used for in-ear noise-masking. These "songs" are only 30-40 seconds long & do not repeat so you can't really jump around in Music Mode making night-long playlists of seaside surf, babbling brooks, thunderstorms, & cello music for falling asleep. The idea is that you select the ONE soundbite you like & mark it as a favorite; that copies the soundbite to the A10's internal memory which will then be used as the default sound for Sleep Mode. During Sleep Mode playback, the soundbite is looped for as long as you keep the buds in your ears. However, you can also fall asleep using the Music Mode's brainwave music feature which supposedly adds in some sleep-oriented brainwave oscillations to the sleep aid soundbites...or so it used to be. As of this writing, the Soundcore app was updated less than a week ago & the brainwave option no longer appears in my Soundcore app even though the instructions for how to get to that page are still in the app's How-To video section :-( Assuming you're still with me, there is just a bit more capability (and confusion) left under the hood. Using the Soundcore app, you can set the buds to use "Smart Switch" which automatically turns off the current audio source from the Music Mode when the app senses you're asleep & switches to the looped sleep aid soundbite you set for the Sleep Mode. This is certainly handy if you want to go to sleep to the melodic sounds of your favorite podcast & then transition to some wind chimes or frog chirps for the rest of the night. But this feature was especially confusing when I first got the buds because I was using the brainwave sleep aid feature from the Music Mode which overlayed some sort of brainwave trickery with a looped song from the Music Mode library--but it was the same "song" that I was using for the looped sleep mode playback, so I wasn’t sure exactly which mode I was still in by the time I woke up. Credit where credit is due--if you don't want to futz with your phone in the middle of the night to engage Sleep Mode (and who would want to if the idea was to keep you as close to being asleep as possible?), you can double-tap the flat surface of the left bud to switch operational modes between sleep & music, & you are even greeted by a softly spoken prompt indicating "Sleep Mode" or "Music Mode"--nice! Double tapping the right bud also starts/pauses playback in its default setting. If you don't like those settings, the app lets you further customize on-ear controls for volume adjustment or playback skip (next/previous), though sadly you can only customize a single command for a single operation (double-tap) per ear...at the very least, I would have appreciated the ability to program a single tap as well. But in a brilliant bit of usability design, the Soundcore Sleep A10s do feature an in-ear alarm. If you manage to sleep all night with these buds in your ears, they can simulate a beeping alarm clock that only you can hear...my wife definitely appreciated the continued silence when I had to get up really early for a medical procedure last week. Other than that, the buds are pretty much your standard mid-tier fare for 2022. Setup was nothing tricky, the buds & case hold a decent charge, & the case features a more robust USB-C port with magnetized recesses to keep the buds from falling out. But the sliding-top case is a bit oversized given how small the buds are & there is no wireless charging option. The white colorway sets these apart from most other buds, but the white ear tips also show wax & dirt *FAR* more readily. Given their decent yet somewhat underwhelming audio performance, decent yet not outstanding sound masking/isolation, and the fiddly sleep aids that are primarily linked back to oddities/weaknesses in the current Soundcore app, the A10s do what they claim to in a resoundingly good, but not great, fashion; some refinement in the app especially could sway my otherwise lukewarm recommendation.

Very Good, Just Short of Great Overall I find the Soundcore Sleep Earbuds to be a solid product. It mostly does exactly what it is supposed to do. I am giving it 4 stars because of some limitations with the product that I am hoping can be fixed with future firmware and/or software updates. Otherwise I would have given it 5 stars. I was eager to try these sleep specific earbuds because I have trouble sleeping and wanted to start keeping track of my sleep patterns. I am also a light sleeper and wanted to try the white noise masking feature. My significant other is also a light sleeper so we were both intrigued by the concept. The first problem that I noticed was that the earbuds sometimes disconnect from my phone in the middle of the night. I am not quite sure why this happens some nights and not others, but it does happen. If this happens all the sleep data after the disconnect is not recorded, and the data before the disconnect can’t be retrieved until the earbuds are reconnected. Another problem I had was that the earbuds are supposed to detect when a person falls asleep and then turn the sleep sound effects off. However, in practice the earbuds sometimes detect that I am sleeping when I am not. Luckily the earbuds can be set to always play sleep sounds. I find the sleep sounds to be very effective masking out other more disturbing noises. Especially considering that these earbuds function as earplugs due to the passive noise canceling. Other than the sleep functions, these earbuds can be used as a traditional set of wireless earbuds by using them in music mode as opposed to sleep mode. I really like the design of the case because it slides open instead of the usual flip up to open. The case uses magnets and sliding the case open is easier than overcoming the magnetic resistance of flip to open cases. Soundcore makes some of the best earbuds on the market, and these earbuds live up to their reputation. The sound quality is excellent. I would have no trouble taking these earbuds with me on a trip and having them pull double duty as sleep aid and wireless earbuds. If Souncore can work out some of the glitches with the sleep mode then they will have a real winner on their hands. Unfortunately for me they sometimes did not work exactly as well as I would have hoped in sleep mode. If I had to guess, I would say that the sleep mode glitched 1 in 5 times or so. My significant other tried them as well and she had the same problems. So they are still very good, but just short of being great.

I have been looking for a replacement for my Bose Sleepbuds ever since they finally gave up the ghost after years of faithful service. These are better than those in a few regards, but an absolute failure of execution in others that make these incredibly frustrating to use. Fit and comfort is Awesome! These beat the snot out of the comfort of the sleepbuds, I can barely tell I am wearing them. Super comfy, and do not budge at all, where as my old ones would fall out of my ear in the middle of the night, and come with so many tips you will find one that works for you. In terms of fit these are absolutely 10/10. The sound library, while a bit more limited, is great as well! Masks sound even better than my old Bose ones ever did, also an absolute 10/10. Now here is why I can only give these 2 stars. The app and general ease of use. My old Bose Sleepbuds had a mode where you could just set a sound, and it would remember it and start the sound up when removed from the case. I did not need an app to switch it over from Music mode to Sleep mode every single time I want to use these. I didn't need the app for more than a minute of setup ONCE in the years I owned them. I don't want a dumb app that I have to open up every single day to switch them from the completely pointless "Music Mode" to sleep mode each night. I know they have the double tap option to switch them over, but the touch commands trigger when they come in contact with my sleep mask that also covers my ears, so that is not an option. These aren't even that good for music, since the music mode battery life is a joke. I could not find anything in any of the manuals or threads online for anything to permanently keep these in sleep mode. I do not care to keep the app on my phone, I do not need the sleep tracker feature since my watch does that better. I just want a pair of sleep earbuds that I can pop in my ears in a few seconds without needing to interact with my phone that I generally keep on the opposite side of my room at night, and lay down and go to sleep with the same white noise audio every evening.

I have been using the Bose Sleepbuds for the past 2+ years. When they died and I learned they were discontinued, I panicked! I did land on these A10s after careful research of some others. The good: I'm a side sleeper and they're comfortable. I mainly have these due to a snoring wife. And, these buds do an AWESOME job blocking out her snoring. I don't hear it at all and I would hear it a bit w/ the Bose. These do NOT have active noise cancellation and rely on a proper, snug fig to tightly seal out the snoring. I was able to get an easy, tight fit without any fuss. There are 4 sizes included and they pop on/off quite easily. You can also run any of your bluetooth apps through it. This is a HUGE win over the Bose as the Bose would only allow sounds pre-loaded in the app. I have not realized any of the connection issues found in other reviews. I may just be lucky so far. Con: The only draw back, and this is kind of a big one. The batteries do NOT last 10 hours in sleep mode. Nope. They are dead every time I wake up in the morning. I'd wager you get about 7 hours. I find this a little annoying because of said snoring during possible sleep in days! Overall, I recommend them, but I am disappointed in the battery life and that's the -1 star!

These sleep earbuds were definitely worth the shot, though I do have a few withholdings: First, the battery life I was not happy with. It's not bad, but the left ear ran out after a little under 7 hours, the other side went out about 30 minutes later. This was done off a full battery's charge by the way. I would think sleep earbud batteries would be designed to last at least a full 8 hour sleep session (not like I ever get that much anyway, but earbuds are supposed to help me get more, haha). A few good things though: they are specifically formulated for sleep, so comfort is top priority with these. They fit right into my ears; similar to a slightly larger ear plug. They are Bluetooth compatible and can function as standard earbuds if needed, but I have some better quality ones for standard listening ---- I'd reserve these strictly for sleeping only. They provide sleep sounds, however I just utilize my own Spotify station for sleep sounds instead. Interestingly, the sounds turned on when my room got extra noisy, so these really are smart earbuds for sure. There is also a sleep tracker, but I track my sleep on my smart watch already so I don't really use this one. At the end of the day, these are basic earbuds that are not much to compare to standard buds, however they have standard buds beat all day long when it comes to comfort and ear fit.

Bought these to replace Bose Sleepbuds. The sound quality is very good. I like the fact you can switch to music from any music app like Pandora and listen. That is a big upgrade from Bose. The drawback is, the music mode drains the battery and you may not get more than 6 hrs (maybe) in music mode. The battery lasts about 8 hours in sleep mode but the promise is 9 hours. As far as sounds there is a wide variety broken down by relaxation, sleep, focus etc. I didn’t like having to pick one and if you want to change then there is a 45 second download time to do so. I recommend since the price comparison to Bose is a third of the price and then work, are comfortable and fit in the ear with a twist. Also there are switch controls by tapping but not for sound just pause and sleep/music mode. These also don’t shut out sounds as well but again Bose not available and are very costly even for refurbished set.

Summary: Though these do not have noise canceling, they do a great job at sound isolation with lots of options for a perfect fit. They work well for falling asleep, though I question the long-term comfort for side sleepers. Also, these are not too bad as regular headphones! Unboxing: The packaging is nice. The package folds out revealing instructions, a large variety of fit options (in ear silicone and fins), the unit and a nice hockey puck charging case. There is a USB cable as well. Setup: Pairing is done via the “Soundcore” app. Pairing was easy with the device quickly finding the headphones but if there are issues, there is a small button on the back of the case to force pairing mode on your device. Use: Prior to sleep, I was impressed to see the plethora of options within the app. After a firmware update, I found a good fit using the included ear tips / wings and put them in. I was impressed that the sound isolation is actually pretty good even without ANC. The easiest way to put it is that you can still hear your kids talk comfortably but background noises seem to disappear. This is with no audio. If you are playing music or white noise (various selections), it does an even better job of blocking noise since you are focused on the audio. Comfort with wear is very good overall (more on sleep later). Within the app there are options for music and many options for various sounds while sleeping. The selection ranges from simple white noise to rain to sea wave. Non music sounds can be downloaded to the headphones directly within the app. Sleep: I am a side sleeper; I had no issues getting to sleep with these headphones and they stayed in the entire night. I have had issues with losing earbuds before as they fall out after inadvertently falling asleep while wearing, not an issue here. Sound isolation was great with some wave sounds and I could hear nothing else. After a few nights I was able to test it while sleeping in other settings. I have a job with some extremely long shifts on some days and people fall asleep while on standby. The sound did an ok job of blocking a snorer nearby but if they are heavily snoring, they will not take care of that. I woke up most nights wearing this as a side sleeper with pain in the ear I was lying on and had to remove them. By that point in the night, I was already tired enough I had no issue falling back to sleep but I could never wear them the entire night on my side. If you are a back sleeper this should be a non-issue. The app can monitor sleep patterns and provide a nice little alarm clock to wake you at set times. I did not see any option for Google Fit integration and am unsure about Apple Health. Audio quality: For music, these are actually pretty good headphones! The only part of the audio range that is weak are the highs. Mids and bass are surprisingly good. I highly recommend these for podcasts, audiobooks or light / lo-fi style music. The drivers are smaller and meant to have lower volume output. The extra bass probably comes from the isolation and depth in the ear canal. Battery: I never ran out of battery for the night. The website quotes them at six hours for music and 10 hours for white noise. With up to four extra charges within the case. These should never die on you. Other notes: -Firmware updates are very small (less than a MB) but they take a very long time to update. -Multipoint Bluetooth is not supported and it seemed to me I had to repair anytime I switched devices, so have a single phone or tablet you use this with -SBC and AAC codecs are supported

These are great sleeping aids. The buds are low profile and work very well for side sleepers. They don’t hurt my ears in the morning like my regular buds do, and they don’t fall out. Plus, their noise isolation even when not in white noise mode are very good. However, you should wait to purchase the upgraded A20, since those are coming out shortly (May 2024). One of the best features, in my opinion, is the built-in alarms for sleep mode. This is the only way to get an audible alarm to sound in your earbuds for waking up. Even after owning these for quite a while, I’m still surprised when the alarm goes off that it’s not an alarm in the room with me. I "forget" that I’m wearing buds by the morning and I wake up looking for an alarm clock! However, the downside to the alarms: You only get three alarms. And you cannot easily change the time–you have to delete the alarm and create a new one if you need to change the alarm time. The sound quality of the A10s are quite good, especially considering the fact that they are mainly designed for sleep noise, not audio streaming. The audio quality isn’t on par with your high-end earbuds, but it’s quite good enough for listening to music or a podcast or watching video before sleeping. Cons: ❯ Battery life isn’t great. If you plan to mask noise all night long, your battery might run out of juice, and then you’ll be woken up with the low battery audio indicator. That’ll be upsetting if you were planning to sleep in! The upcoming A20 promises to extend battery life even more. ❯ Bluetooth connection stability isn’t great. I would often start off streaming audio from my phone while watching a video before switching to Sleep mode. However, the connection would often drop or become distorted and I would have to reset the buds in the case and reinsert them to continue. At times this was bad enough that I seriously considered returning them. But I did appreciate their utility as a sleep aid, so I kept them. Also, there is a noticeable lag in the streaming, so if you’re watching a movie, you may get distracted by the lack of sync between actors’ lips and the words they’re speaking. This isn’t a deal breaker, but an annoyance. ❯ Sleep sounds via the built-in library are limited. I was hoping for some binaural beats or customizable EQ for brown noise, or blending multiple sounds (like myNoise). So, sometimes I use my preferred noise generator and stream the audio, but that means lower battery life and the usual Bluetooth stability issues during streaming. The buds are most reliable when in Sleep mode and using the on-board sleep sounds. I hope that with the release of the A20 the sound library gets improved. ❯ The sleep monitoring and reporting is unreliable. I would often check my sleep stats to see when the buds clocked my deep sleep and wakefulness patterns, but very often I found that it mis-recorded my actual sleep times, and sometimes was missing whole days. I stopped even looking at the sleep reports after a while. All in all, while I have occasional frustrations due to Bluetooth reliability, the alarm interface, the untrustworthy sleep pattern reports, and battery life, I’m glad I bought the A10 version and look forward to the release of the A20.

I have two sets of sleep earbuds, the now-discontinued Bose Sleepbuds, and these Anker A10 sleep earbuds. I accidentally broke one of my A10 earbuds recently, and immediately bought another set. The A10s work fine, connect quickly, and are easy to use, and here are some ways I think they could go from pretty good to really great. 1) My number one suggestion is to design the rubber tips to be better earplugs, even without music or sounds. This contributes to better sound masking right away, and I can hear a clear difference between the A10s and the Bose, the latter of which has a great earplug effect. A10s rubber tips seem only to be designed to keep the bud in your ear, Bose's are designed to keep noise out. 2) The app is quirky - there is a "sleep mode" setting where the same sound is uploaded to the earbuds and plays all night. (This feature of the earbuds works great.) Strangely, in order to pick the sound to upload you have to switch to the "music mode" setting (standard bluetooth operation) to change the "all night" sound. Once you get used to the app, it works well. 3) For sleep sounds, there are frogs, rain, pink/white/etc. noise, light piano music and the usual stuff. In my experience, those don't mask varying-pitched and varying-volume sounds like nearby music, traffic, or talking. Some background sound apps allow combinations of sounds to be created (car ride + rain + cafe sounds) that can mask out most varying outside sounds. It would be ideal for Anker to allow combined sounds in the app, or provide more sounds that are intended to mask varying noises. I gave the A10s four stars because they're affordable, work well, can double as standard bluetooth earbuds, are easy to find online and locally, charge quickly, and connect every time. Anker seems to be improving these by providing more rubber tips and ear "wing" shapes than in their original release. I took one star off because I want them to work harder at being good earplugs and provide a better library of sleep sounds. Overall, I'm happy with these and they do the job, and I recommend them.

Great when they work, battery life leaves a lot to be desired. I do really like these sleep buds as opposed to a dedicated white noise sound machine since they passively block external noise, as well as provide a masking sound. They are really comfortable in the ear, and do stay in place the entire night. I am a side sleeper and they actually stay in my ears the whole night without loosening out and losing the seal. I know everyone's ears are different so everyone's experience with these will be different. There's 2 main gripes I have with these however. 1) Battery life doesn't even last through a night with my right bud. I start the night with them fully charged, and every time I wake up, the right one is dead. Sometimes even after only about 5 or 6 hours. Not sure if they're defective or what is going on, but I'll wake up and the left one is sitll going albeit, almost dead, but the right one is definitely off. There have been some nights only about 5 or 6 hours of sleep. I wake up and expected them to both be working but the right one was off. I reconnected them and checked the app and the right one was dead. The second gripe, When you go to use them, they default to music mode. I wish there was a setting to lock them to sleep mode, or have an option to select which mode it defaults to when pulled out of the case. I never use music mode with them, and I'd venture to guess most people using them have trouble sleeping and use them to assist in sleep and not listen to music. I just want to pull them out of the case, and have it start in sleep mode instead of fiddling with an my phone, an app, Bluetooth etc. every single night. As it works now, you have to turn BT on, on your phone, open the app, connect the buds to the app and select "sleep mode", then turn BT off and go to sleep. Also I wish there were more options for white noises. A lot of the sounds available are city sounds, water type, insects etc. Most people probablt use some different frequencies of white noise but there's only two, maybe 3 options for white noises. For reference- Yes, everything is up to date, firmwares etc. I don't even use "music" mode. Pull them out and turn on sleep mode right away which is supposed to be better on battery life. I wish there was a way to completely disable BT wireless while using them and only have BT enabled for sound transfers or FW updates while in the case. I would imagine this would extend battery life significantly.

I can't tell you the number of sleep earphones I've tried...everything from a headband with flat speakers in them to Kokoon nightbuds. I can't speak to the app or its functionality as I only use these strictly as a means to listen to my Calm app. However, the comfort of these are some of the best I've tried. They're small enough, and have enough fitment options, that they work for me, even as a side sleeper. The only issue I seem to have, is that they don't seem to stay paired with my phone. I will lose connectivity with one side or the other. I end up having to take the offending bud out, put back in the charger, and when I remove it, it pairs up again. So, these aren't 100% reliable for me but still one of the better options I've tried.
