A:Answer Hello Nells,
Thank you for considering Sony products!
We appreciate your question and are happy to assist you. The WH-CH520 headphones support the Advanced Audio Distribution Profile (A2DP), which enables wireless audio streaming from compatible devices. To connect your WH-CH520 headphones to your TV wirelessly, please ensure that your TV also supports the A2DP Bluetooth profile. You can verify this by checking your TV's specifications or user manual. If both devices are A2DP-compatible, you should be able to pair them directly for wireless audio playback. For TVs that do not support A2DP, consider using a third-party Bluetooth transmitter connected to your TV's audio output to enable wireless connectivity with your headphones.

Best regards,
