Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Tribit Stormbox Micro 2 ranks #1 of 62 small speakers by sound quality at $35.39; the Bose Soundlink Flex ranks #38 of 179 medium speakers by sound quality at $79.99.
The Tribit Stormbox Micro 2 is the lighter pick. 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 Bose Soundlink Flex at 1.3 lbs (589 g). It has an adjustable EQ, which the Bose Soundlink Flex lacks. Watch for: Finicky phone charging, which doesn’t usually work.
The Bose Soundlink Flex is the deeper-bass pick. A small, rugged waterproof speaker that survives drops and floats, with a warm, bass forward sound for casual outdoor use. Its bass reaches about 56Hz before falling 10dB, against 65Hz for the Tribit Stormbox Micro 2. It links with other speakers (Bose Party mode), which the Tribit Stormbox Micro 2 cannot. The tradeoff: Warm sounding with overly boosted bass which drowns out midrange detail.
Buy the Tribit Stormbox Micro 2 at $35.39 for a small speaker, or the Bose Soundlink Flex at $79.99 for a medium speaker instead.
