It's not just the ruggedness that impresses here—the unit sounds even better than its predecessor. The Charge 6 relies on proprietary AI Sound Boost to deliver optimal audio performance with less distortion, making your favorite tunes truly shine. On top of that, you can customize the sound extensively with a seven-band EQ, accessible through the JBL Portable app. Just like the JBL Xtreme 4 and the Flip 7, this fella lets you share the vibe with companion speakers through Auracast. That helps create a louder soundstage with deeper bass for truly memorable gatherings. As far as battery life goes, you can expect up to 24 hours of music. That said, the unit boasts a new Playtime Boost feature that extends total playtime by an extra four hours. Audio quality diminishes once you enable the feature, so keep that in mind.Add to that a built-in powerbank, and you've got what's likely to become the next fan-favorite JBL speaker. If you're impatient and don't want to wait for Prime Day 2025 deals on Bluetooth speakers to start popping up, now's your chance to save 15% on the JBL Charge 6.
