JBL Charge 5 vs Bose Soundlink Flex 2nd gen

Last updated: October 1, 2026

Short answer: the JBL Charge 5 for battery and durability, the Bose Soundlink Flex 2nd gen for a warm alternative. The Charge 5 doubles as a USB-A power bank, is IP67 rated for a 1m dunk lasting 30 minutes, and runs about 20 hours, though it is not stereo and sounds warm with shouty upper mids and boosted bass. The Bose is pretty much identical sounding to the 1st gen, with overly boosted bass that drowns out midrange detail.

Bose Soundlink Flex 2nd gen ranking card

Older model: the Bose Soundlink Flex (ranked lower, 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.
