Hello there, thanks for the response.
<p style=”text-align: left;”>Yeah, I followed the instruction via the manual. Exactly the same issue as in this thread: after pairing, the H90 wasn’t available in H90 control as a device. When selecting ‘Add Device’ it was blank under ‘Select Port’, so connection couldn’t be completed.</p>
I tried deleting the app, unpairing and pairing again. I tried to connect via usb and then back to Bluetooth. The only thing I didnt do was restore the H90. I eventually got it to work. The only thing I did differently was plug the i-Pad into mains supply, even though it had a 75% charge. I disconnected and reconnected today on the battery, to check if that was the problem, but it connected with no issue at all. It was obviously just a glitch.

Cheers, Justin
