On bluetooth, when I select : "Speakers (HK Onyx Studio 4 stereo)" > the pairing is faulty, always on and off. When I select "Headset Earphone (HK Hands-Free) > pairing is correct for minutes and disconnect. Speaker removed and reconnect many times

Asked by: Chebby
Hi, please try to see if pairing the HK Onyx studio 4 to other phones/ tablets does the same thing. If it does, please try to reset the Onyx Studio 4 by pressing and holding the Vol + and the Phone button at the same time until the unit powers off. Don't forget to remove the device from your phones's bluetooth list before you pair again. If it still occurs, please submit a case request and so we can assist you:​ https://www.harmankardon.com/support-contact.html

Can you use HK Remote App with this speaker? I have it hooked up to my record player and I want to be able to remotely control my volume.

Asked by: Aaaa4322
Unfortunately the HK Remote app doesn't work with the Onyx Studio 4 as the app only works with certain HK receivers. Thank you.
