Bose Soundlink Flex 2nd gen - ranked #37 of 164 Medium Size Portable Bluetooth Speakers · Editor's rating 3.8/5
Check price at Amazon ($159.00) →

Older model: the Bose Soundlink Flex (ranked lower, rated 3.8/5).

Smaller model: the Bose Soundlink Micro (rated 3.5/5).

Larger model: the Bose SoundLink Max (rated 4.3/5).

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.
