It’s been a few years since we’ve looked at Ultimate Ears’ Boom speaker lineup — the company’s 2015 Boom 2 and Megaboom were both solid performers that have held their own for the past three...

I wonder if there's a future for speakers like the Boom 3. The industry trend is towards smartspeakers, and even UE is veering in that direction with its Alexa-enabled Blast line.

I am very pleased with this speaker. It's very easy to pair and it can be paired with multiple devices. I use it with my phone for music and that Waze GPS app. I use it with my Amazon fire stick. The suround soud is great. I will buy another one soon.

So easy to use and has an awesome sound. We've got two of these so far and they are easy to link up. Can't wait to get even more!

I loved this speaker and still do but there are some connectivity issues when trying to link more than 2 of these. Sound is fabulous and it is truly water resistant; accidentally left it outside one night in a rainstorm semi protected by a tree. The speaker wasn’t affected. Battery life is great.

This is a fabulous portable speaker. The sound quality is way better then I ever expected for such a small device. Not heavy so you can pack it just about anywhere. Highly recommend this guy.

Great sound, easy portable size. Very happy with my selection of Ultimate Ears Boom 3.

I've had this speaker for about a year now. I did test to see if it was waterproof when i visited a friend NC. Stayed at a hotel with a pool and listened to music there. Out of curiosity i threw the speaker in the pool while it was playing. It immediately stopped playing. but it did float.

25 July 2019

this is the best speaker that Logitech (Ultimate Ears) has produced - it does NOT support telephone or voice commands - it's just a speaker - to me this is a BIG benefit. the ability to know the battery (press and hold "Plus" and "minus" symbols simultaneously) is a big improvement to having to log...

I constantly get compliments on this speaker’s sound quality. I have it set up on a shelf at work, and it last several work days of constantly playing. I haven’t tested it’s water resistance personally, but I’ve seen a friend’s MEGABOOM fall into a lake and float, and after patting it dry worked...

Its such a good price for the sound. Yes, I struggled trying to connect to my computer and phone. After much moaning and talking to myself it was done. I'm not even going to try to connect them to my 10 year old smart tv. What did I have to do to get the bluetooth in my devices to find this thing.

Hubby love's it. It's a great size, say bit bigger than energy drink can. The power, and sound out of it is amazing. We're going to buy another one just for me.
