Hi,
Just bought the HD10BT's and love the sound (especially when using Sonarworks) but the issue I have is the constant beeping whenever I do something on the Mac or the iPhone (with or without listening to music at the same time) such as zooming in or out of a website, changing app, turning the volume up or down etc etc. Literally driving me insane to the point I'm thinking of returning them. Read somewhere else on here that its an issue with iOS in general and to turn the phone off and reset the headphones. Tried that and still exactly the same. This doesn't happen on all headphones as I have 2 other bluetooth headphones (AirPods and samsung) and neither do this,
