Big, loud, heavy, sturdy, holds charge, doesnt take long to charge, doesnt take to much space, great for indoor or outdoor use. Works with all our devices.

Absolute best Bluetooth speaker you can find. Solid slamming bass with zero distortion at max volume. I went down a deep dive rabbit hole to find something that would actually satisfy me in the long run. Multiple Bluetooth speakers were purchased and returned very quickly in my journey. A gentleman on the phone with Best Buy told me that he was certain that what I was really looking for was an Ultimate Ears Hyperboom. He wasn’t wrong. I’ll never look back. This thing absolutely pounds. I used Alien Tape to secure four Milwaukee Packout feet to the bottom of the speaker so that I can lock it in on top of a Packout box in the back seat of my Subaru WRX so that it stands nice and pretty and secure and doesn’t get thrown around in the car while I drive the whip the way it was designed to be driven. I have received multiple compliments when getting out of my car at establishments from strangers, telling me that the sound system in my vehicle sounds really good. I always chuckle when I get to tell them that it’s just a Bluetooth speaker in the back. There is no ”just” about this speaker. Even simply picking this thing up by its collapsible handle is confidence inspiring that what you’re about to hear is going to be substantial. The Joker has quite a bit of weight to her and rightfully so with the size and number of drivers they fit into this box. On the top of the speaker is a microphone that the unit uses to listen to itself and adjust its own output based on the space that it is sitting in to ensure the best possible sound in any type of setting or environment. Wide open field, she sounds amazing. Corner of the bathroom when you take your shower, total immersion. Out on the boat, give her a splash and a couple of wet high-fives for being so dang gangster. I’ve had this thing sitting in the pouring rain for over an hour straight. Zero issues. Truly waterproof. Way to go, Ultimate Ears. You guys make some killer stuff. This is my first of your products, and I cannot tell you how happy I am with this HYPERBOOM. 10 out of 10.

Great sound !! Im sooo happy with my purchase i did the right election.

A very last minute purchase due to my company needing a quick speaker system for an event. This event was in a windy, open parking lot in front of a faculty and it carried our music and speakers voices amazingly well. The sound quality is also very balanced. There was about 65 people in attendance and everyone was able to hear just fine. Would buy again.

[Employee of bestbuy] One of my favorite speakers around. I always have 2 of these in case of a small party or event. Using 1 at a time is solid as well. Put it in front of a wall for more bass. The only thing thay compares is the JBL Boombox 3.
