Wonderful Sounding Speaker

Great sound coming out of the onyx 8. So impressed with the sound I bought a second one and now paired them together to make a stereo.

Amazing product

The Harman Kardon Onyx 8 is wonderful and I love it. If I could, I would buy multiple. I have one issue: why does a device made in 2022 not have any EQ app? I live in an apartment where I love listening to music, but it gets too loud and I don’t want to disturb my neighbors. Not being able to adjust the bass is my only problem. Other than that, the sound is clear and great.
I would recommend this to a friend!

Does not sync
on December 6, 2025
Posted by: Gwest
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. If you need further assistance, please contact us.

Possible lemon but bad battery for sure

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!

Great Sound and good for large rooms!!

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!!!
