Short answer: the Ultimate Ears Boom 3, if you are buying new. The Tribit Stormbox Pro ranks higher than it (#46 vs #114 of 175 medium speakers, 3.7/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Boom 3 is still sold new at $134.99. The Tribit Stormbox Pro’s replacement, the Tribit Stormbox Max, is still sold new.
The Tribit Stormbox Pro is the better-sounding, deeper-bass option. 24 hour battery life (60% volume, XBass off); doubles as a power bank. Its bass reaches about 58Hz before falling 10dB, against 91Hz for the Ultimate Ears Boom 3. It is rated for 24 hours of battery against 15 for the Ultimate Ears Boom 3. It supports aptX Bluetooth, which the Ultimate Ears Boom 3 lacks. The tradeoff: Bottom woofer was fixed in a later firmware, upgrade for best sound.
The Ultimate Ears Boom 3 is the lighter option. 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 Tribit Stormbox Pro at 2.2 lbs (980 g). It links with other speakers (PartyUp up to 50 speakers), which the Tribit Stormbox Pro cannot. It plays in stereo from a single unit, unlike the Tribit Stormbox Pro. Watch for: Not stereo, barely any bass, recessed treble.
Buy the Ultimate Ears Boom 3 if you want one new; the Tribit Stormbox Pro is discontinued, so only look for it used.
