Our Verdict

Harman/Kardon Onyx Studio 6

JBL Xtreme 3

The JBL Xtreme 3 is a slightly better speaker for most uses than the Harman/Kardon Onyx Studio 6. The JBL has a better-balanced sound profile and better directivity. It can also get louder than the Harman/Kardon, it has more compression artifacts at max volume, and it has an outstanding battery life. However, the Harman/Kardon supports voice assistants through your smartphone. Its Bluetooth latency on Android and iOS is also much lower.
