I need to be able to listen to the audio from my television normally during the day, and with wireless headphones at night. So far, my plan consists of a receiver with some bookshelf speakers (since anything plugged into the TV prevents the TV from using its own speakers), but I don't know what to use for the headphone step. I'd rather not use an FM transmitter, and the headphones MUST be wireless. I can't use an app like Tunity, since much of the TV being watched is recorded shows, and I've been unable to find any auxiliary to bluetooth broadcasters that I can use with general bluetooth headphones. Any suggestions? Price isn't really an issue.
Be aware that Bluetooth has a range of about 30 ft max.
You will need a set of Bluetooth headphones, and there are many options for that. You will also need a Bluetooth audio transmitter, which gets plugged into the headphone jack of the TV, and paired with the headphones. I have linked to such a device below.
