Short answer: the Marshall Emberton III, if you are buying new. The Tribit Stormbox Pro ranks higher than it (#46 vs #126 of 175 medium speakers, 3.7/5 vs 2.7/5) but is discontinued, so only consider it used; the Marshall Emberton III is still sold new at $129.99. The Tribit Stormbox Pro’s replacement, the Tribit Stormbox Max, is still sold new.
The Tribit Stormbox Pro is the better-sounding pick. 24 hour battery life (60% volume, XBass off); doubles as a power bank. It supports aptX Bluetooth, which the Marshall Emberton III lacks. It keeps a wired aux input, which the Marshall Emberton III lacks. The catch: Bottom woofer was fixed in a later firmware, upgrade for best sound.
The Marshall Emberton III is the longer-running, lighter pick. 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. It is rated for 32 hours of battery against 24 for the Tribit Stormbox Pro. At 1.5 lbs (673 g) it weighs noticeably less than the Tribit Stormbox Pro at 2.2 lbs (980 g). It links with other speakers (Marshall Stack), which the Tribit Stormbox Pro cannot. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Marshall Emberton III new; the Tribit Stormbox Pro is no longer sold new, so it only makes sense as a used find.
