Customer Ratings & Reviews

This was a Father’s Day gift to my husband. The speaker is used around the pool area and delivers great sound with the security of knowing that it’s water resistant. Great portability and holds a charge for days. Would not recommend for a large party but for some adults hanging out on the deck it’s got great sound. I would buy this item again.

The MegaBoom Speaker is an absolute powerhouse when it comes to portable audio. Its sleek design, durable build, and impressive sound quality make it a must-have for any music lover on the go. With 360-degree sound and deep bass, every song comes to life with rich, immersive sound that fills the room. The long-lasting battery ensures hours of uninterrupted listening, perfect for outdoor adventures or parties with friends. Plus, its water and drop-proof construction give me peace of mind knowing it can handle whatever comes its way. The MegaBoom Speaker truly sets the standard for portable audio excellence.

I considered other larger speakers for the sound, but the mega boom matched the sound quality and volume of similar priced speakers. The diameter of this speaker makes it easy to hold, it hasn't slipped out of my hand once when picking it up, and it fits inside my till box quite well for storage at work. The battery is rated at 20 hours, but If I play it at Max volume, it will only last about 6 hours. Listening at 60% to 80% volume can easily get me 12 hours of play time, at which point I remember to plug it in to charge while listening. Overall I've been quite happy with this purchase, and my co workers are impressed by the sound quality. It produces way more bass than a speaker this size should be capable of.

As just a speaker you'd set down on the counter while doing chores or in the shower it'd be worth 5 stars. BUT I specifically bought this speaker with the intention of using the sync mode. I even convinced a good friend of mine to buy one also. We were planning on taking them along on our trips to the river for tubing. First the good: I haven't dropped it yet or anything so I can't speak about how rugged it is. It does feel like it has solid build quality though. It floats in water and can be completely submerged for a short time with no problems. Battery time has been good for me, 6 hrs at max volume per use on a full charge. And the app was straight-forward. As far as sound quality goes, it sounds as good as what you'd except it to sound like for the price but the bass is nothing to write home about. Volume is a little louder than I expected Now the bad: The sync feature was extremely lacking in terms of connectivity. Any distance greater than about 5 feet made at least one of the speakers start crackling or cutting out completely. This was no good considering the distance between 2 people each holding a speaker is about 3 feet from the getgo while sitting on the float tubes. While floating down the river there's a lot of variation in how the tubes are pulling each other so your physical proximity from the next person is constantly changing meaning bad connection in this case. Naturally our goal of putting each speaker on opposite ends of our group was out of the question. After deciding to only use one, we quickly discovered that if there's any interference at all and the speaker loses signal quality, we would have to restart it completely by cycling power. This was despite the speaker still showing as connected on the connected phone and in the app. For context, you're sitting in a tube floating down the river with your phone in a pouch hanging off a lanyard. Every now and again your phone takes a small dip under water for whatever reason and this constantly cut the connection. This is not an issue we have ever had with any other speaker including a homemade one with a very cheap bluetooth receiver. This review applies to both the speakers we had (my friend's and mine). They behaved exactly the same so I'm not sure if they were part of the same batch and maybe defective or something like that but I'm returning mine for sure. He may also not sure yet. Again, good as just a normal speaker as stated in the intro

Beats the jbl system, I'm using it right now. Sounds great, plenty loud, use it in the shower, literally, it's completely waterproof. It even floats, but 200 is steep. I would say 150 max but i paid 99$ and i wouldn't see getting rid of it anytime soon. Great battery life as well, only needing a charge every 2 days or so and i use it all day, workouts, drives, studying, shower, cleaning. It's a great well built speaker and the 360 sound really will blow your mind.

I will just say its a really nice speaker with good bass It also connects to your Bluetooth devices really well. The battery life has been good and long lasting, although My kid could say more on that since he uses for the shower more Over all, a well built speaker.

This speaker blew me away! I’ve done extensive research on portable speakers and hands down this was the best one. The ability to link this with other UE speakers and that this is one of very few Bluetooth speakers that outputs stereo sound was a major selling point It sounds great both indoors in small and large rooms. The speaker fills the room with sound. Outdoors, it excels in sound quality and loudness. Would highly recommend over any other similar size speaker.

Pros: Plays loud with little distortion, good bass extension, battery life, multiple speakers can be paired together Cons: Micro USB charger, no aptX, a bit expensive for what it brings to the table

Excellent sound for the price. Very solid bass and sounds good when cranked up loud. Bluetooth connection is relatively easy and strong. It does require an app on your phone to utilize most features & EQ, but that enables a sleek and minimal design. Being able to link up with another Boom or Megaboom speaker for stereo sound is a great plus that you'd expect from big-ticket folks like SONOS

The Ultimate Ears Mega Boom 3 packs a serious punch in both sound and durability. Its impressive audio quality fills any space with rich, clear sound, while its rugged design makes it perfect for outdoor adventures. With its waterproof and dustproof construction, along with long battery life, this speaker is a true powerhouse. Whether you're at a party or on a camping trip, the Mega Boom 3 delivers an unbeatable audio experience. Highly recommended for music lovers on the go!

I have not really had any portable speakers in the past that are worth mentioning, so getting this was a big upgrade for me. Before I purchased this speaker it was pretty much just me listening to things through my phone speakers. Which worked for me fine for a while but I enjoy music and have people over for get-togethers. So having a speaker for being able to take outside and be able to hear was important to me. This speaker is surprising to me with the amount of sound it puts out. The sound quality is very good. I also like how you can tweak the sound settings through the app, it is a cool feature to have. As far as this speaker is waterproof, I haven't tested that part out yet. I do use it outside frequently so it is nice to not have to worry about potentially getting water on it. I am very happy with it and would recommend it to anyone looking for a portable speaker in this price range. I looked at some other speakers but was impressed by the battery life on this one. It is pretty true to the battery life shown on the specs.

This is an excellent Bluetooth speaker! I’ve had other UE products, and this did not disappoint. The sound quality is very clear, and has a nice bass to it. This speaker can be very loud and has a great Bluetooth range. The battery life is superb also. Looking forwards to many years with this speaker.

While the looks can be deceiving, being that it is a small speaker, this little guy is amazing! I have had a Bose and Marshall speaker back in the day and figured I wanted to get an upgraded speaker. This tiny little speaker was indeed impressive. While I based my decision to purchase off of reviews here and YouTube reviews, I bought it with skepticism thinking it would be mediocre. I figured, let me try this out fresh out of the box in my car in which I was not too impressed with it. I tried it in my bedroom and that’s where the magic happened. The sound quality definitely delivered as the music was bouncing off the walls. It doesn’t stop there, but you can connect these to other Ultimate Ears products! In finding this out, I really want to purchase the Hyperboom to go with this little guy (if you haven’t already demod this, go to a Best Buy and try this sucker out) At the end of the day, I believe this little one is worth it because you can take it wherever you want, super portable and it is also dust and water proof! Highly worth the value. I would also recommend the Hyperboom.

UE's Megaboom 3 is, in my opinion, one of the best portable bluetooth speakers for the money. I am impressed with the sound quality and bass output for its size, super long battery life, and the app that’s available for download for both Android and iOS devices. This speaker is built like a tank! Strong and durable shell with waterproof protection(waterproofing has limitations and tolerance factors) means I can listen to it almost everywhere I go. I do plan on the purchase of at least one, or maybe more, Megaboom 3's because you can link up to 150 of them together for an immersive sound experience.

Lasting battery. I sometimes falling asleep with the speaker on and the battery barely moves. The sound is amazing! I don’t need to turn the volume all the way up either. It’s s turdy on different surfaces and the app makes it easy to use when I’m in another room. Overall, a great speaker. I love it!

Great speaker. The app is easy to use and you can power the speaker on and off using the app. Fantastic battery life. I’ve used this speaker outside while doing yard work and it sounds great.

I love UE Booms and my previous one lasted for almost 8 years before my battery stopped charging. I was really excited for this one being the upgraded version both in sound quality and battery life. While this one is good i figured i would be blown away by the difference and i just wasnt. It seems like they focused more on how water resistant it was and how you can throw it in a pool than user friendlyness. The new design has some features that bug me. You have to have the app in order to pair/use. There are two buttons on the top. The small one you use all the time is the power button, the big "magic button" one pairs when pushed and held to turn on...seems like they could have done this a different way. When you turn on the boom it makes the "on" schwoop/ pair noise at what sounds like full volume and cant be adjusted. All that said, for the money i dont think you can get a better unit. The only thing is this just left me wishing that my old speaker wasnt broken instead of being happy i upgraded to this one.

I love the design, very durable and it's waterproof. The sound quality is also very good. I use it for my small salon business. it's great for a small room or business. Also I like how it has an app that you can turn on and off and connect via your devices remotely. Overall very satisfied with the item. :)

Compared this Megaboom 3 to the similarly priced Bose soundlink revolve, revolve +, JBL, Sony, and a few other brands. The Bose and the UE Megaboom 3 were equivalent in clarity and by far better than everything else. The MB3 dominated everything at this price point for bass. This little thing packs a decent bump for the size. The Bose Revolve was muddied and unsatisfying. It took the significantly more expensive revolve + to get to the same base quality. The JBL has a decent and clean bump for the bass but the overall sound quality is lacking. The app works well, nothing special about it but a nice remote turn on feature that works without any problem. It has some preset equalizer settings but I haven’t played with those too much. Just picked the one that worked best for my garage and haven’t touched it since. So far, I have been using this in my garage for the weekends and can go the whole weekend on a single charge. I would roughly estimate my usage at about 14-15 hours at medium to high volume. Not maxed out though. If I max out volume, I can hear it in my neighbors garage 2 houses down and across the street. So battery life seems great as far as I am concerned.

Bought this for the wife…. She loves it and I must admit the quality of sound in this thing is pretty amazing. We replaced a bigger portable speaker with this one and this one is almost have the size and pack a solid punch. The bass from this things isn’t overwhelming but quite noticeable. Again extremely happy with the sound from this unit.
