Does not sync

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.
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 use a pair of these in my office and the link system is absolutely amazing. Stereo sound from 2 independent, powerful speakers. Pairing is simple and switching channels is as well. I've now had the Studio 2, 4 and 8 speakers and they have all been fantastic. I still use all of them.
I like this speaker. Great audio, well balanced between the low frequency, mids and high tones. I like how it is also powered by a cord and not rechargeable battery. Also a plus that this speaker can take calls or be used as an audio source for virtual meetings.
Bought one sounded great got another to stereo link worked a couple times but now they won't link. Still working on it. It shouldn't be this difficult.
