Thank you for purchasing a Panasonic product.
I'll offer a few tips to address your question, and follower with a disqualifier.
Check the Bluetooth profiles your television supports in the Specifications Section of instructions that came with your Panasonic Smart Television. The television must support one of these two Bluetooth profiles: A2DP or HSP. If your TV supports one of these two profiles, find the BT menu on the television, put the television is search mode, make certain you headphones are on, When the television asks; May I pair with Headphones" click yes.
