I have Bose Bluetooth headphones which I have been able to connect wirelessly with my LG tv. My problem is with volume control. I can only adjust the volume using the the remote. The buttons on the headphones do nothing. The tv remote adjusts both the headphones and internal tv speakers simultaneously so that a comfortable level on the tv is too quiet and a louder volume on the headphones is too loud for the tv. Is there a way to adjust the volume on the two devices independently of one another?
