Ultra-portable and ultra-durable, the active black WONDERBOOM 3 Portable Bluetooth Speaker from Ultimate Ears is made to deliver big, 360° sound on your outdoor adventures. Dynamic and bass-heavy audio is pumped out of dual 40mm drivers with dual passive radiators, which you can double up with the purchase of a second WONDERBOOM 3. Whether alone or in a pair, the WONDERBOOM 3 can handle a day of hiking, camping, or hanging out at the pool, as it's both waterproof and dustproof. In fact, it can even float if dropped in the water. On a full charge, the WONDERBOOM 3 can play your streaming audio all day, with a battery life of up to 14 hours, and it pairs quickly to Android mobile devices thanks to Google Fast Pair support.
