Short answer: the Ultimate Ears Wonderboom 4, if you are buying new. The Tribit Stormbox Pro ranks higher than it (#46 vs #109 of 175 medium speakers, 3.7/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Wonderboom 4 is still sold new at $74.50. The Tribit Stormbox Pro’s replacement, the Tribit Stormbox Max, is still sold new.
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 14 for the Ultimate Ears Wonderboom 4. It supports aptX Bluetooth, which the Ultimate Ears Wonderboom 4 lacks. It keeps a wired aux input, which the Ultimate Ears Wonderboom 4 lacks. The tradeoff: Bottom woofer was fixed in a later firmware, upgrade for best sound.
The Ultimate Ears Wonderboom 4 is the lighter pick. At 0.9 lbs (420 g) it weighs much less than the Tribit Stormbox Pro at 2.2 lbs (980 g). Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
Buy the Ultimate Ears Wonderboom 4 if you want one new; the Tribit Stormbox Pro is discontinued, so only look for it used.
