Our Verdict

Bose SoundLink Color II

Bose SoundLink Flex

The Bose SoundLink Flex is a better speaker than the Bose SoundLink Color II overall. The Flex is better built and has a better-balanced sound profile that can produce a more extended low-bass than the Color. That said, the Color has a longer-lasting battery life of almost 10 hours, though this can vary depending on your usage.
