These are not really the same size class, and that is the honest framing here. The Tribit Stormbox Micro 2 ranks #1 of 62 small speakers by sound quality at $35.39; the Soundcore Boom 3i ranks #31 of 179 medium speakers by sound quality at $118.99.
The Tribit Stormbox Micro 2 is the lighter choice. An excellent sounding small speaker, with surprisingly deep bass for its size and a strap that holds it on a bike or backpack. At 0.7 lbs (317 g) it weighs much less than the Soundcore Boom 3i at 1.7 lbs (783 g). The tradeoff: Finicky phone charging, which doesn’t usually work.
The Soundcore Boom 3i is the deeper-bass, longer-running choice. A warm, punchy waterproof speaker that sounds great and is a strong value. Its bass reaches about 56Hz before falling 10dB, against 65Hz for the Tribit Stormbox Micro 2. It is rated for 16 hours of battery against 12 for the Tribit Stormbox Micro 2. It supports AAC Bluetooth, which the Tribit Stormbox Micro 2 lacks. The catch: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
Buy the Tribit Stormbox Micro 2 at $35.39 if you want a small speaker. Buy the Soundcore Boom 3i at $118.99 if you want a medium speaker instead.
