Our Verdict
Harman/Kardon Onyx Studio 6
Harman/Kardon Onyx Studio 8
The Harman/Kardon Onyx Studio 8 is a step up from the Harman/Kardon Onyx Studio 6 in many ways, though it lacks its predecessor's IPX7 rating for water resistance. The new generation has a more balanced default sound profile, a longer continuous battery life and it can playback stereo content without downmixing to mono. It also has better controls, allowing you to accept and decline calls, as well as pair with another Onyx Studio 8 to create a true wireless pair. However, the Onyx Studio 6 has lower latency with iOS and Android devices, making it a good choice if you watch a lot of videos or movies.
