Short answer: the Turtlebox Ranger. It ranks #65 of 166 medium speakers by sound quality, rated 3.5/5, at $250. The Ultimate Ears Boom 3 ranks #111, rated 2.9/5, at $134.99, $115.01 cheaper, which does not close the gap in sound quality.
The Turtlebox Ranger is the better-sounding choice. Smoother frequency response than the other Turtlebox speakers. It charges over USB-C rather than Micro USB. The tradeoff: Bass sounds kind of thuddy and isn’t as deep as higher ranked speakers.
The Ultimate Ears Boom 3 is the lighter choice. 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. At 1.3 lbs (608 g) it weighs much less than the Turtlebox Ranger at 2.4 lbs (1.09 kg). It has an adjustable EQ, which the Turtlebox Ranger lacks. It plays in stereo from a single unit, unlike the Turtlebox Ranger. The catch: Not stereo, barely any bass, recessed treble.
Buy the Turtlebox Ranger. It is rated higher for sound quality, and saving $115.01 with the Ultimate Ears Boom 3 does not make up for the sound-quality gap.

The Two Speakers In Full
Turtlebox Ranger: $250.00 Amazon eBay
Same family: the Turtlebox Cub (smaller model, rated 3/5), the Turtlebox Gen 3 (larger model, rated 2.1/5) and the Turtlebox Grande (larger model, rated 2.6/5). See every Turtlebox generation.
Pros: Smoother frequency response than the other Turtlebox speakers. Has magnets for attaching it to things. Appears to be quite tough
Cons: Bass sounds kind of thuddy and isn’t as deep as higher ranked speakers. Overpriced. Heavy for the size, likely due to the toughness

Ultimate Ears Boom 3: $134.99 Amazon eBay
Newer model: the Ultimate Ears Boom 4, ranked higher, rated 2.9/5, released Jun 2024. See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
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.
