I got a bluetooth headphone (RockNgroove) gifted by my son. I have already paired with my cell phone. I want to use this also for hearing TV (samsung smarat tv) through this BT headphone (not simultaneously with my cell phone) . My TV is NOT BT enabled. what should I get 1) Bluetooth receiver , which I already have,2)BT transmitter or 3) 2 in 1 bluetooth receiver and transmitter. My tv has audio out jack and also toslink. The solution should be easy as I am old. Normally I am the only person to view and hear TV and no other person.
