Customer Ratings & Reviews

OK sounding speakers and can connect to multiple speakers at once it nice. I found the sound tiring after a while and the software to link the speakers was cumbersome tedious and not reliable for speakers that have been around so long I would have expected more mature implementation. It just tired my ears defeating the great battery life, portability and water proof. Real shame I ended up returning the 2 I purchased.

The megaboom 3 delivers great sound to our pool deck and we love the portably of this speaker! Also like it's waterproofness and it's overall durability

Our friend has the Sony of similar size which has a light show attached to it. I went with the UE which was on sale and included the charging base because I felt the audio was more authentic. It is still simply a Bluetooth speaker and I use it now mostly to send lecture audios to it from my phone or iPad. The audio is similar to that from my large Amazon Echo, but this can be moved around the room. Neither, however, have a jack to connect a device directly and bypass Bluetooth, unfortunately.

This speaker is wonderful! Durable, sounds GREAT and the battery life hasn't been a disappointment. I also own the megaboom 2 and love that you can link them together. I would definitely recommend this whole line.

The UE Megaboom 3 is one of rhe best all around Bluetooth speakers on the market, even years after its release. The sound is full and rich, the form factor is perfect for almost any situation and its super easy to pair and use. The UE app makes things easy to set the sound just the way you like it. I did detract one star for the charging port, its still mini USB.

LOVE LOVE LOVE this speaker. Couldn't speak highly enough, I've had it for 3 years, battery life is great. I bring it down the river all the time and nothing has ever happened. 10/10 would highly recommend if you are in the market for a speaker!

Very good product I bring on vacation 360 sounds around is fantastic love it Full recommend.

The Ultimate Ears MEGABOOM 3 portable speaker is decent, but not outstanding. The design is sleek and the waterproof/dustproof feature is a plus. The sound quality is good, but not exceptional. The battery life could be longer. Overall, it's a decent option for those in need of a portable speaker, but there may be better options on the market for the price.

Excellent bluetooth speaker: works in water, audio is high quality, easy to pair, and sturdy enough to take on trips.

Awesome portable, wireless, Bluetooth speaker! Waterproof/dustproof design.

Bought it as a gift and it’s a blast to use! Gets plenty loud for outdoor use with great sound quality and the waterproof is a great piece of mind when using outside.

I love it i have the smaller one also. great buy the sound is Great i love that i'm able to carry it anywhere and it's waterproof. and floats

It’s easy to set up with its app. It floats if it GSS all’s in the pool and plays plenty loud. Insane battery life.

The sound quality is amazing!!! Great bass and also is very easy to use.

Great sounds and great battery life. And compact not to big.

Great sound, tremendous battery life and waterproof to boot! I got it for poolside tunes.

I work in a warehouse where i have to wear earplugs. This gets loud enough for my work area to hear my music. Its also nice that it doesnt have to be at full volume and doesnt leak too far to my coworkers stations.

These speakers sound so good, rich full sound with a punch and very good volume. Also you can link other Ultimate Ears speakers together to play on every one all at once in sync. Also they can be used outside and by the pool. There is nothing quite like this on the market. Easy to use as well.

Big sound. A bit too much on low end, but most people will like that. Battery life is good and it’s ultra portable. Really wish they included the charge dock.

I work in the Construction field specifically on towers, Ive owned all of the Megabooms 1, 2 and finally 3. This is by far the best sounding speaker ive owned,deep bass and clear voice no distortion (even in the wind). i love the anchor point on the speaker so that i can easily attach a lanyard and hang it pretty much anywhere. the fact that its resistant against water has always been a huge factor in deciding which speakers i purchase. underground ears is the best speaker hands down.
