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!

The boom 4 is very portable and powerful bluetooth speaker

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!

I really like this speaker. It has a great sound in a small footprint. The battery last long also.

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!
