#111 Ultimate Ears Boom 3: $134.99 Amazon eBay

Newer model: the Ultimate Ears Boom 4, ranked higher, rated 2.9/5.

Pros: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp. Measured bass extension of 91Hz (-10dB).

Cons: Not stereo, barely any bass, recessed treble. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2021. Lots of mentions of failing batteries on amazon. Not technically a 360 speaker, only front and rear.

Related speakers: Ultimate Ears Boom 4.

How it compares: Just above it: Ultimate Ears Boom 4 - $35 cheaper. Just below it: Klipsch Groove - $46 cheaper, 7 fewer hours of battery life.
