This is my second Onyx Studio. The last one I purchased nearly ten years ago and still sounds as great as the day I bought it. Thank you for making a high quality product at an affordable price!
I bought this to replace an older model and I wasn't disappointed! What great sound! Bone vibrating bass and a high end that is crisp and clear. There is nothing close to HK quality in this price range from any other company.
I bought 2 of the Onyx Studio 8 speakers. I wanted to connect them to my TV. I can connect 1 but not the other. I read online how to connect the 2 speakers together but it’s only worked 1 time. Unable to find any real documentation from Harmon Kardon on how to connect multiple speakers, however they do advertise the functionality. Very disappointing! Sound from 1 speaker is amazing, I only wish I could reliably connect 2 speakers.
No, I would not recommend this to a friend.

Thanks for your feedback. The wireless connect feature of our HK Onyx Studio speakers is designed primarily for use with mobile devices and tablets. While you can attempt to connect it to your TV, please note that you may experience delays or lip-sync issues due to the inherent latency that a Bluetooth connection encounters.
To connect two Onyx Studio 8 speakers, power them on, connect one speaker to your TV, and then press and hold the Bluetooth buttons on both speakers for 5 seconds. You will hear a notification sound when they are connected. If the connection does not work, try pairing them with your phone or tablet to replicate the issue. If you encounter problems with your phone or tablet as well, please contact us directly for further assistance at this link: https://support.jbl.com/us/en/#contact.
Got for my hubby for Christmas. He had to test it out the moment he opened it. He's so super happy, got it for the garage gym. Super loud with super bass. Definitely happy
Sound is very good! Excellent, deep bass. Real glad I got them. Pairing to a phone or ipad is easy. The only improvement is making pairing to another Studio 8 easier, as it's cumbersome.
