Owners point the Bose SoundLink Flex (2nd Gen) at buyers wanting a small, portable speaker with surprisingly punchy bass for its size, and people who'll pair two units for stereo sound, widely praised as excellent.
Owners point the JBL Clip 5 at outdoor/active users who clip it to bags, belts, or golf carts for hands-free carry, and buyers wanting a tiny speaker with surprisingly loud, punchy sound for its size.
The most-cited downside of the Bose SoundLink Flex (2nd Gen) is a firmware update added a jarring, loud startup/shutdown chime with no way to disable or lower its volume, repeatedly startling owners and waking people at night.
