Customer Ratings & Reviews

I bought this solely to use with my tablet whenever I'm chillin in the kitchen or outside. This speaker definitely packs a punch. Very loud, clear. The mids are dense and crisp. The bass is heavy, but doesn't drown out the sound. Bose has definitely made a name for themselves. But this speaker outlives the hype of any other brand I've ever used for audio. It pairs to both my phone and tablet seamlessly without any effort. And the app is very nice too for adjusting the sound quality.

the loudest with an amazing bass that BOSE portable Bluetooth Speaker yet, easy to pair with multiples electronics equipment at the same time like pairs with TV and iPhone and another device at the same time

Christmas gift for my wife. She loves it! Lots of low end. I love it, too!

The Bose SoundLink Flex (2nd Gen) Portable Bluetooth (5.3) Speaker packs so much quality sound into a small package - I would say it is incredible, but it is BOSE after all. Since the day I got this, I have been absolutely loving it! The speaker is charged via a USB-C cord, which is included, but I have those all over - for my phone, etc. so I simply plugged it into one to charge while I downloaded the Bose app. The Bose app has a handy little equalizer you can set, but really other than that I don't see where I will have much use for it. The speaker came almost fully charged, so it didn't take much time to be ready to go. Intuitively, I pressed the bluetooth logo on the speaker and searched for the speaker name on my phone's bluetooth list. It connected immediately and, though Bluetooth speakers generally have approximately 30' connection range, I was able to walk all over my house carrying the speaker and even outside into the yard without any connection issues at all. How is the sound? MAGNIFICENT! Connecting to Spotify or my phone's playlist, I get that amazing Bose bass that fills my soul with incredible sound that I can feel. The treble is awesome as well, and can standout more for you if you do an adjustment in the equalizer. I prefer a little more bass over treble with less mids. The sound is clear and amazing at any level and this thing can blast the sound! If you're having a party, this is all you will need for your playlist. With its shortcut button capability, you can pair it with another SoundLink speaker for even bigger sound. You can even use that button to create a shortcut - I chose to use it for Spotify and when I press that shortcut button, the speaker connects to the Spotify app on my phone. Bose claims a 12 hour battery life, which is long enough for a day in my life, though they do state that at maximum volume the battery will last approximately 3 hours. The Bose SoundLink Flex (2nd gen) is light to carry at just 1.66 pounds and has a nice feel with it's soft-touch, silicone-wrapped finish and it is dust proof and waterproof (rated IP67). This is truly portable because Bose built it to withstand, as they say: "drops, crushing, shocks, and rust", and it has a small hoop to hook it onto your gear. As I was writing this review, my phone rang and I was able to answer it via this speaker! There is a built in microphone so the caller was able to hear me, but said I was fading in and out, though I was sitting in one spot. I was able to hear them clearly. The other problem was that I didn't know how to hang up via the speaker - I had to have them hang up (of course I could have used my phone). This Bose SoundLink Flex (2nd Gen) Portable Bluetooth Speaker puts out absolutely incredible sound in a small speaker (H 2.06 inches, W 8.661 inches, D 3.78 inches). This is quality that I appreciate and that I know will last for a good long time. It is everything I want in a portable speaker and I would HIGHLY recommend it to anyone in the market for an excellent quality small Bluetooth speaker.

From the moment I powered on the Bose SoundLink Flex II, I was immediately impressed with its sleek design and build quality. This compact, portable speaker doesn’t just look good; it feels sturdy and I see no issues using it at home or on the go. The audio quality is good. For a speaker of its size, it delivers a surprising sound experience. The bass is deep and punchy without being overwhelming, and the mids and highs come through with clarity. I tested it with various genres, from classical to hip-hop, and it handled everything with ease. This speaker is especially good when you crank up the volume. The PositionIQ technology optimizes the audio base on what position it is in. It’s lightweight and compact enough to fit into a backpack or tote, or hang off either via the built in strap. The stated battery life is 12 hours, and I actually exceeded that during my initial "let's see how long this lasts" period and the speaker recharges quickly. The speaker has an IP67 rating, meaning it’s dustproof and can withstand being submerged in water. It also floats, but it's not designed to be used in the water but can withstand a drop in a pool or rains storem. The Bluetooth connectivity is straightforward and reliable. Pairing it with my devices was a breeze, and I appreciated the strong, stable connection that didn’t drop even when I moved around the room. It also supports voice assistants, which adds a layer of convenience for hands-free control and has various setting available in the Bose app including custom sound setting. The Bose SoundLink Flex II is a top-tier portable speaker, that also has the ability to utilize a "party mode" where it will share a connection with other Bose speakers. Whether you are an audiophile or someone who wants a reliable speaker for outdoor adventures, this little powerhouse won’t disappoint.

It’s a Bose, so as you might expect it sounds great at low, mid, and full volume. It’s waterproof, sand / dust proof, and shock proof which I love in a portable speaker. It feels solid and well built. It has a built-in strap that seems durable and lets you clip it to backpack, etc. (clip not included.) The Bose app is simple to use. It also gives you EQ options with some preset options (Bass Boost, Bass Reducer, Treble Boost, Treble Reducer) and you can manually set Bass, Mid, and Treble up/down 10 each. Personally I think it sounds best at Bass +8 and Mid +2 settings for a deeper sound. I put it through the paces on every musical genre and most sound great (rock, rap, dance, folk, country, classical, etc.). Bass heavy music I’d love a tad more bass, but that’s difficult to achieve in such a small package. It sounds good whether laying down, upright, or hanging from its strap. Buttons are easy to use and intuitive including a configurable shortcut button (Link mode/party mode for combining with another Bose SoundLink Flex, Access with Voice Assistant, and Spotify) It has multi point connection to connect with 2 different BT source devices. Battery life is rated at a solid 12 hours, but likely depends on the volume you’re jamming out at. Charging is thankfully USB-C. It weighs about 1.5 pounds so it’s light, but not a featherweight. Overall a solid, rugged, great sounding portable speaker.

The speaker is compact enough to hold in your hand, tuck into your pack, or attach to the outside with its sturdy utility loop. The Flex 2 boasts a 12-hour battery life and an IP67 waterproof rating. With advanced Bluetooth 5.3, it ensures a robust, uninterrupted connection to your device from up to 30 feet away. Multi-point connections allow the speaker to be paired with several devices simultaneously, facilitating easy sharing of DJ responsibilities with friends. A notable addition is the Shortcut button, which provides quick access to various functions, including instant pairing with another speaker. Whether standing upright, laid back, or hung upside down, the SoundLink Flex consistently delivers optimal sound. Bose's PositionIQ technology detects the speaker’s position and adjusts its output for the best performance. Bose speakers are known for their agreeable sound, and the latest SoundLink Flex is no different. It offers clear sound with surprisingly good bass for its size, and the volume can reach impressive levels. Vocals come through clearly, and overall, the audio quality surpasses expectations for a speaker of this size. The accompanying app has been updated recently, allowing EQ adjustments through the Bose app. It also facilitates "SimpleSync" pairing with another compatible Bluetooth speaker. In Stereo Mode, one speaker serves as the right channel and the other as the left, while Party Mode synchronizes two speakers to play the same audio. The Bose SoundLink Flex (2nd Gen) Portable Bluetooth Speaker delivers exceptional sound in a compact form, embodying the quality I value and expect to last. It meets all my criteria for a portable speaker, and I would highly recommend it to anyone seeking a top-quality small Bluetooth speaker.

I’ve been using the Bose Soundlink Flex II for a little while now, and honestly, it’s quickly become my go-to portable speaker. Right out of the box, the setup was super easy – it connected to my iPhone in seconds, and I was ready to play my music. For such a small speaker, the sound is amazing! It’s got this rich, deep bass that you wouldn’t expect from something so compact. Whether I’m listening to music or catching up on podcasts, everything sounds crisp and clear. Plus, if you really want to step it up, the Bose app lets you link two of these speakers together for an even bigger sound. Perfect for a small gathering or an outdoor hangout at the park. Speaking of outdoors, this thing is built with that in mind. It’s both water- and dust-proof, so I don’t have to worry about it getting wet by the pool or dusty when I take it camping. It’s tough and portable, but still stylish enough to leave out in the living room. All in all, the Bose Soundlink Flex II is a quality speaker with serious punch for its size. If you’re looking for a portable speaker that delivers big on sound and durability, this one’s a winner.

It is honestly astonishing how big the sound is coming out of this compact gem. I don't know what engineering voodoo Bose is using, but their speakers blow everyone else away in terms of audio balance. There's bass, but it's never overpowering. There's treble and it's never tinny. If I want to hear a song played well, this is how I play it. The fact that it's so small and lightweight (and water resistant!) means I can pick it up and go anywhere in the house, or throw it in a suitcase. And for the price, you can't go wrong.

I wasn't totally vlown away with the Bose SounLink Flex portable speakers compared to others I have or have heard. Out of the box it's a solid well built product. Has a usb-c port which is nice and comes with a usb to usb-c cord in case you dont have one. The silicone wrapped body feels good in the hand and seals it up tight to be dust proof and water proof, it floats very well in the pool. The built in loop is a good touch, I can see many uses down the road for that. Be sure to download the bose app to be able ro adjust the sound settings, makes a big difference. At first impression I would have dropped a couple stars but I went ahead and purchase a second one to see if two paired together really made a difference and it really did. As one speaker, it's not my favorite, but paired and in stereo they sound amazing. I probably would have dropped to four stars without knowing the potential. There seems to be a passive subwoofer in the rear of the speaker, so setting it against something solid gets better bass notes out of the speaker. All in all, its just all right alone. Phone calls were seamless with zero complaints, all genres of music sounded about the same. If you can swing two then go for it, if not then look elsewhere.

Amazing, clear sound. I bought this speaker due to its features advertised. It is waterproof like it said. I use a pressure washer to was my car at home. It didn't damage it when the mist got on it. The bass on this speaker is unbelievable. You'd think it was a larger speaker with the sound output. It can fit into your pocket if you want to take it places and dont have a carry case. I would definitely recommend this speaker if you want a small one. You need to download to Bose app to get the best sound settings.

This speaker sounds great. Nice bass. Live that it has an equalizer to make adjustments to sound. This small speaker performs to the high standard fie which Bose is known. I love the portability. This speaker may not be for everyone, but it is perfect for my use. I use it in my craft room. I use it when sitting outside. I recently used it for a trunk or treat event. I also love the color options.

I made an excellent choice! The Bose Speaķer is clear, no static, The volumoe, the base, everything is excellent excellent with the Bose Portable 2nd Generation Speaker.

Sounds amazing for its size. Its a great speaker small enough to bring along and with awesome Bose sound. It has good bass.

As a former Sony and JBL speaker loyalist I was pleasantly surprised at the sound profile and capabilities of the Bose soundlink flex. I compared the speaker to the Sony ULT(the smaller one not the massive one) and the JBL charge 5 and boy was I impressed, Although not exactly punching you exactly the same bass wise as the JBL the Bose made up for it in clarity and lack of distortion at higher volume Clear winner over the Sony and it just edges the JBL charge 5 via clarity vs sheer sound.

Excellent sound, sounds like a big home stereo system, good bass and treble, battery life is great

Great sound, good bass, speakerphone works great, easy to connect.

Sturdy design , clear bass , equalizer , best battery life

Great sound quality, very good bass when played on flat surface and laid speaker side up. EQ adjustments in the app are also a major bonus. Played side by side with an older UE boom speaker (which had been great and served its purpose) but this was definitely a worthwhile upgrade. Was between the flex 2 and new beats pill 2

This speaker is amazing! Plus you can customize the treble & bass through the app. I bought one for my 19 year old daughter a year ago & she uses it all the time. I wanted one for myself. The sound is waaaaay better than the Beats Pill. I have Bose speakers in my car, amazing sound. Especially if you like bass.
