Short answer: the Ultimate Ears Wonderboom 2, if you are buying new. The Tribit Stormbox Pro ranks higher than it (#46 vs #111 of 175 medium speakers, 3.7/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Wonderboom 2 is still sold new at $80. The Tribit Stormbox Pro’s replacement, the Tribit Stormbox Max, is still sold new.
The Tribit Stormbox Pro is the better-sounding, deeper-bass choice. 24 hour battery life (60% volume, XBass off); doubles as a power bank. Its bass reaches about 58Hz before falling 10dB, against 82Hz for the Ultimate Ears Wonderboom 2. Alan Ross Reviews measured it at 99dB at full volume, against 88dB for the Ultimate Ears Wonderboom 2. It is rated for 24 hours of battery against 12 for the Ultimate Ears Wonderboom 2. Watch for: Bottom woofer was fixed in a later firmware, upgrade for best sound.
The Ultimate Ears Wonderboom 2 is the lighter option. IP67 rated and floats. At 0.9 lbs (420 g) it weighs much less than the Tribit Stormbox Pro at 2.2 lbs (980 g). The catch: Not stereo, barely any bass, recessed treble.
Buy the Ultimate Ears Wonderboom 2, since the Tribit Stormbox Pro is discontinued and only worth hunting down used.
