Ultimate Ears Boom 4 Portable Waterproof Bluetooth Speaker with 360-Degree Immersive Sound, Outdoor Floating Speaker, 15-Hour Battery, 147ft Range – Black by Ultimate Ears

Ultimate Ears portable speakers are the best on the market.

My original one from 10 years ago still works perfectly, sounds amazing, and the battery still powers the thing for like 8 to 10 hours on a full charge. I use it 2-3 times a week for many hours at a time.

I’ve even taken it on multiple inner tube float trips (in a ziplock bag). I’m the most popular guy on the river. I’ve gotten enough free beer to pay for the damn thing.

I clean it a few times a year with a damp rag and a shop vac and it still looks brand new, except for some minor polishing on the rubber over power button.

I bought the UE Boom 4 to pair with the old one for stereo sound.

It’s incredible. The sound is amazing!

If this thing holds up like the original, I’ll probably never need another portable speaker.

Except, I’m probably going to buy 2 more to have surround sound stereo wherever I go and whenever I want it.

Can’t say enough good things about this company and their products.

Buy one. You’ll love it.

The sound quality is ok, because it is not very loud. At full volume, the battery will be completely dead in 4 hours. At 3/4 volume it will be dead in 5 hours. It doesn’t charge while plugged into a usb automobile cigarette lighter.
I bought the mega boom 3, it was certified refurbished, I wasn’t paying attention, a co worker sent me the link, 3 songs , the speaker was rattling, and by the time I got home from work, it was filled with water.
I am a city letter carrier in Vegas, I am outside at least 7 hours a day, and just from leaving a cooling towel on the already rattling speaker, it managed to fill this waterproof speaker with a cup of water, and it never worked again.
So whether it’s new or refurbished, I can honestly say that Ultimate Ears Boom4 and mega boom 3 are crap.
I had a $28 dollar JBL, that was as loud, and took 2years to blow out the speaker.
I am assuming the megaboom4 is no better.

As a speaker, the Boom 4 is great, nice clear, well balanced sound with decent bass. Obviously for something this size the bass is not particularly powerful but it is still adequate.

I particularly like the design, the outer surface has a nice almost clothlike texture and the big bold volume buttons are fun and functional.

The app adds some nice extra features like EQ and a very convenient ability to remotely turn the Boom 4 on or off. The remote power option is really nice but it doesn’t always work as smoothly as I would like. I often have to try to connect with the Boom 4 in my phone settings before trying to power it on remotely but it does eventually work. Battery life is solid too, standby mode barely drains it at all.

Other than that, the Boom 4 is a very enjoyable speaker with a lot of power for its size and nice, clear sound quality.

Maybe not the cheapest speaker on the market, but the sound is great and the extra is worth the it. Long lasting battery too

Excellent! I should have bought this earlier, but I bought the 2010 speaker of Logitech 305 at $438.91, although I got to know it is merely around $50 than and now. While Logitech Speaker breaks every time when I hear the sound, this speaker gives me excellent audio. Finally, I feel comfortable about using a speaker and don’t need to use my headphone.
