Our Verdict

JBL Xtreme 2

Harman/Kardon Onyx Studio 6

The JBL Xtreme 2 and the Harman/Kardon Onyx Studio 6 have similar overall performances, and depending on your listening habits, you may prefer one over the other. The Harman/Kardon has a more neutral, balanced sound profile out-of-the-box. However, the JBL has a better soundstage performance, longer battery life, and it supports voice assistants from your smartphone, unlike the Harman/Kardon.
