Short answer: both are discontinued, so this only matters if you are buying used. Used, the Tribit Stormbox Pro is the better pick: it ranks #46 of 175 medium speakers by sound quality (rated 3.7/5), against #112 (rated 2.9/5) for the Ultimate Ears Wonderboom. If you want one new, the Ultimate Ears Wonderboom 4 replaces the Ultimate Ears Wonderboom and is rated 2.9/5 at $74.50.
The Tribit Stormbox Pro is the better-sounding, longer-running option. 24 hour battery life (60% volume, XBass off); doubles as a power bank. It is rated for 24 hours of battery against 10 for the Ultimate Ears Wonderboom. It keeps a wired aux input, which the Ultimate Ears Wonderboom lacks. It has an adjustable EQ, which the Ultimate Ears Wonderboom lacks. The tradeoff: Bottom woofer was fixed in a later firmware, upgrade for best sound.
The Ultimate Ears Wonderboom is the lighter choice. IP67 rated and floats. At 0.9 lbs (425 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 Tribit Stormbox Pro only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Ultimate Ears Wonderboom 4, which replaces the Ultimate Ears Wonderboom.
