Short answer: the EarFun Uboom 360 for the better 360 presentation, the Ultimate Ears Boom 3 for battery and PartyUp pairing. The Uboom 360 likely shares drivers with the Maxsound Plus and is likely the best 360 speaker around, though it is not stereo, rolls off slightly in the treble and is not as deep in bass as the best in its category. The Boom 3 adds an excellent 15-hour battery and IP67 floating construction.
The Ultimate Ears Boom 3 impresses with: Rich, warm bass without muddying the mix, crisp highs, an excellent 15-hour battery life, stable Bluetooth, an IP67-rated floating design with a rugged fabric shell, and the ability to pair with up to 150 speakers via PartyUp. It comes up short on: not being stereo, barely any bass, recessed treble, still shipping with micro USB, plenty of reports of failing batteries on Amazon, and not technically being a 360 speaker, only firing front and rear.
The EarFun Uboom 360’s pitch: It sounds similar to the Maxsound Plus, likely sharing the same drivers, and is likely the best 360 speaker around. The compromise: it isn’t stereo, has slightly rolled off treble and not as deep bass as the best in its category, and isn’t technically a 360 speaker, only firing front and rear (outdoor mode is flatter, indoor mode boosts bass).
Buy the Ultimate Ears Boom 3 if you want one new; the EarFun Uboom 360 is discontinued, so only look for it used.
