Audio interference - Plantronics headset and other bluetooth devices
I was having a few weeks of unresolved audio skipping from my Plantronics Focus headset. Playback and recording were both effected. When I disconnected both of my other bluetooth devices, an Apple Magic Mouse 2 and Apple Trackpad, the problem disappeared.
The solution was to simply go to Bluetooth preferences, delete the headset, and repair. Thirty minutes later, both mouse and trackpad are connected, and perfect audio.
Simple fix that took me more than two weeks to figure out. Tried to reply to other threads with same problem, but the threads were locked. Hope this helps someone else.
