JBL Flip 5 vs Bose SoundLink Flex

The Bose SoundLink Flex is better than the JBL Flip 5 overall. The Bose offers a better-balanced sound profile that can produce a deeper bass than the JBL. It's better built and can get a bit louder with less compression at max volume. It also supports voice assistants through your paired smartphone and is excellent at understanding your commands from far away and in noisy settings. That said, the JBL is just a little bit smaller, and it has better directivity, so its soundstage is perceived as a bit wider than that of the Bose.
