Jabra ENC010 and Insignia ns-pu37h-bk adapter conflict. With adapter attached the headset has no audio.

SOURCE: Not sure if Jabra bluetooth headset or charger that not working

I had the same problem, called support, they told me battery is defective or too old and doesn't accept the charge. Battery in a headset is hardwired and can't be replaced, so the whole thing is trash :(
