Fiddly, but works. With my Samsung Galaxy S9, got the hang of it. The instructions are minimal, but I got stereo working on my two Harmon Kardon Onyx 4 speakers (the app only works for Onyx 4). Connect both speakers via the phone's Bluetooth, then open the app. Press the link button on both speakers at the same time, then tap the same icon in the app and choose stereo. You're all set.

Can't see my speakers to connect them in stereo, even if my phone connects with no problems separately. Useless app... Edit: I have tried 2 types of omni and 3 versions of onyx studio which work separately, but nothing in this app.

Terrible app or speaker won't connect to my onyx studio 6. I can play music but the app will not connect. Can't update the software on the speaker. The speaker is buggy
