The JBL Charge 6 is a worthwhile improvement on the popular JBL Charge 5. The Charge 6 offers improved waterproofing, a handy carrying strap, and extra silicone feet around the passive radiators at each end of the speaker. It also supports Auracast, so you can link it with other Auracast-enabled JBL speakers for parties or larger gatherings. The Charge 6 also has a more even and punchy bass performance. That said, the differences in sound and battery life are minor, so if you have a Charge 5 already, the upgrade might not be worth it, and if you can find a Charge 5 on a great deal, it's well worth considering. Still, the Charge 6 is the better speaker, all things considered.
