Wow, I love the Onyx 8, but I wish it had little more treble at the top end and a little less bass at the bottom. If it had EQ app or bass and treble controls it would be perfect. For what I paid it is a just great!!!
I bought this 2 weeks ago not too happy with it because there was three occasions where the battery lasted about 2 hours. I gave it a second star because the quality is great but the description States the battery will last 8 hours and that's the downfall.
I would recommend this to a friend!

Thanks for your feedback. We appreciate your input and we'll make sure to forward it to the appropriate team.
I purchased this Onyx Studio 8 only for the purpose of being able to sync it to my other Onyx Studio 8. Unfortunately, I’ve been unable to do so.

Thanks for your feedback. To activate Wireless Stereo Boost on the Harman Kardon Onyx Studio 8, simply turn on both speakers, then press and hold the Bluetooth button on your primary Onyx Studio 8 for 5 seconds, then do the same on the second speaker to pair them together, and ensure that they are within 10 meters of each other.
