Our Verdict

JBL Charge 5

Bose SoundLink Flex (2nd Gen)

The Bose SoundLink Flex (2nd Gen) and the JBL Charge 5 are very comparable portable speakers with different strengths. Both speakers have IP67 ratings for dust and water resistance, but in our tests, the JBL's battery lasted a lot longer than the Bose's. If voice assistants are important to you, you'll want the Bose, as it does an excellent job of supporting them on your smartphone.
