Our Verdict
Bose SoundLink Flex (2nd Gen)
JBL Charge 6
The JBL Charge 6 and the Bose SoundLink Flex (2nd Gen) are both portable speakers designed for everyday and outdoor use, but they have different strengths. The JBL is larger, has a longer battery life, and gets louder. It also supports Auracast multi-speaker pairing with other Auracast-enabled JBL speakers, making it ideal for bigger spaces or group listening if you've a suite of compatible models. On the other hand, the Bose is smaller, lighter, and easier to carry. It offers a more balanced sound at moderate listening levels than the JBL, but only pairs with other 2nd Gen SoundLink Flexes.
