JBL Elite 750NC not working via bluetooth
I can't get to play audio via bluetooth on my wireless JBL Elite 750NC headset.
I can do the pairing (not without some headaches) and the device successfully shows up in the bluetooth devices menu, but then I can't select it as sound output. When I click on the device in the sound tab, it is endlessly stuck on the loading icon. It seems that the macbook also is forcing the headset to switch on and off because it would continue to turn on and off itself without me doing anything about it.
I've been rebooting the macbook and resetting the headphones and forgetting existing pairing multiple times without success. The headset works with my android phone and other devices.
