Bose Soundlink Flex 2nd gen vs Tribit Stormbox Mini+

Last updated: October 12, 2026

Short answer: the Bose Soundlink Flex 2nd gen. It ranks #37 of 175 medium speakers by sound quality, rated 3.8/5, at $99.99. The Tribit Stormbox Mini+ ranks #142, rated 2.5/5, at $31.99, $68 cheaper, which does not close the gap in sound quality.

Bose Soundlink Flex 2nd gen vs Tribit Stormbox Mini+

The Bose Soundlink Flex 2nd gen is the better-sounding option. A very portable 1.3 lbs (586 g), IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. It supports aptX Adaptive Bluetooth, which the Tribit Stormbox Mini+ lacks. 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.

What the Tribit Stormbox Mini+ does well: IPX7 waterproof, app support with EQ presets and AAC codec, true wireless stereo (TWS) capability, USB-C charging, built-in mic for calls, AUX input, microSD card playback. It keeps a wired aux input, which the Bose Soundlink Flex 2nd gen lacks. It plays in stereo from a single unit, unlike the Bose Soundlink Flex 2nd gen. The tradeoff: Not a great sounding speaker, really weak bass.

Buy the Bose Soundlink Flex 2nd gen. It is rated higher for sound quality, and the $68 you would save on the Tribit Stormbox Mini+ does not close the gap.

The Two Speakers In Full

Bose Soundlink Flex 2nd gen ranking card

Older model: the Bose Soundlink Flex (ranked lower, rated 3.8/5). See every Bose SoundLink Flex, Micro, Max and Plus generation.

Same family: the Bose SoundLink Max (larger model, rated 4.3/5), the Bose Soundlink Micro 2 (larger model, rated 3.6/5) and the Bose SoundLink Plus (larger model, rated 4.2/5).

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.
