As loud as the Mega Blast, just smaller/better!
Peaches Posted
I previously owned the mega blast, and was hesitant to buy a new one despite the mega blast starting to die on me after a few years of loyal service and excellent jam sessions. I finally pulled the trigger on getting one of these little ones because it’s pool season again, and I wanted to have some jams at the pool. Everybody is blown away by the amount of bass that this thing produces despite it being so small - it’s about the size of a really big Red Bull can, and fairly lightweight that you can throw it on a rope and carabiner and hang it from a bag and still get great jams out of it without feeling the weight drag you down. EASILY worth the money, especially considering how much you’re going to use it on a daily basis or at least for every pool session. Small enough to fit in the center console of my bronco for a chill beach session as well!

Simple design, great sound quality!
SteveNYC Posted
Battery lasts a long time, the sound is phenomenal, and its narrow design allows for it to take up minimal counterspace while on its charging dock. Using its corresponding app allows it to also work as a, “public address” speaker while music plays on the speaker. Very worth the price!

Great Sound

Great sound in this wireless speaker. We were at our community pool and someone had the same Ultimate Ears Boom 4 speaker playing. I Asked her where she bought it and what the name of it was. The next day I went to the Best Buy app and ordered me one. Now I am the talk of the pool with my new Boom 4 waterproof wireless speaker!

Battery doesn’t hold a charge
JuanE Posted
Sound quality is solid and the build feels durable, waterproof design is a nice touch. Unfortunately, mine developed a battery issue after just a few weeks — it charges fully but dies within about 2 hours of normal use, nowhere close to the advertised battery life. Went through all the troubleshooting steps (resets, different cables/adapters, cleaning the port) with no luck. Currently working through a warranty replacement. Disappointing for a product in this price range.

Unstoppable sound for the pool and beach!
CHRISTOPHER Posted
The BOOM 4 absolutely delivers. The 360-degree sound is super crisp with impressive bass for its size. The best part is how worry-free it is around water—it’s floating in the pool right beside us, perfectly fine. Dustproof, waterproof, and extremely durable. Battery life gets me through the whole day without a hitch. 10/10 recommend!

Great small speaker

Great little speaker that pairs great with bigger UE speakers. Particularly adds tons of sound when used with the UE Hyperboom, but also good portable speaker
