These sit in different size classes, so this is not a straight ranking comparison. The Tribit Stormbox Micro 3 ranks #6 of 47 small speakers by sound quality at $59.99; the Bose Soundlink Flex 2nd gen ranks #35 of 144 medium speakers by sound quality at $159.
Why pick the Tribit Stormbox Micro 3: Tribit Stormbox Micro 3 uses 48mm NdFeB driver with coaxial passive radiators. The tradeoff: Bass is limited by its 62Hz specification.
Why pick the Bose Soundlink Flex 2nd gen: A very portable 586g, IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. The catch: One Flex remains mono and cannot deliver genuine low-bass rumble; RTINGS also found the elevated treble can turn hi-hats and other high-frequency detail piercing.
Buy the Tribit Stormbox Micro 3 ($59.99) for a small speaker; the Bose Soundlink Flex 2nd gen ($159) suits a medium speaker instead.
There is a real battery-life gap here: the Tribit Stormbox Micro 3 is rated for 24 hours, the Bose Soundlink Flex 2nd gen only 12 hours.

Tribit Stormbox Micro 3: $59.99 Amazon AliExpress eBay
Older models: the Tribit Stormbox Micro 2 (rated 4.5/5) and the Tribit Stormbox Micro (rated 4.3/5).
Pros: Tribit Stormbox Micro 3 uses 48mm NdFeB driver with coaxial passive radiators. Its 330 g, claimed 24 hours (Manufacturer specified) battery life, IP68 protection, up to 93dB and mono playback make it a practical option for its intended room or portable use. PartyUp and Auracast party mode link multiple speakers. Measured bass extension of 62Hz (-10dB).
Cons: Bass is limited by its 62Hz specification. Bass is thuddy and distorted by default and needs EQ.

Bose Soundlink Flex 2nd gen: $159.00 Amazon eBay
Older model: the Bose Soundlink Flex (rated 3.8/5).
Pros: A very portable 586g, IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. The second generation adds a Bose app with 3-band EQ, better-placed controls and stereo pairing with another Bose Soundlink Flex 2nd gen. It supports AAC and aptX Adaptive in addition to SBC, making it a stronger wireless option than most small rivals.
Cons: One Flex remains mono and cannot deliver genuine low-bass rumble; RTINGS also found the elevated treble can turn hi-hats and other high-frequency detail piercing. The claimed battery life is only 12 hours, and some owners report accelerated standby drain after firmware updates. It is expensive for its size, so the added app and codec support, not a transformational sound upgrade over the original, are the main reasons to choose it.
