If you like to watch TV late at night and are worried about waking up a spouse or child, headphones are an obvious solution. Many TVs come with a headphone jack, so hooking up a pair of headphones is easy and convenient. If you do any moving around while you're watching TV, or if you simply don't want wires intruding on your space, wireless headphones are a great alternative.
Set up the transmitter. Wireless headphones rely on a transmitter that sends audio via infrared or radio waves to your headset. Use the digital audio output (coaxial or optical), RCA outputs (red and white) or headphone jack on your TV to connect the transmitter. The connection will depend upon which outputs are available on your TV and/or the transmitter.
Use an RCA-to-headphone adapter. If you don't have a headphone jack on your TV and the transmitter includes only a headphone connection, connect an RCA-to-female headphone connector. This will allow you to plug the wireless transmitter into the female headphone end and then hook the RCA ends into your television's audio outputs. You may also need a 3.5 mm (mini jack)-to-1/4-inch adapter if the headphone plug on the transmitter doesn't match the television jack.
Set the transmitter on top of, or next to, the television. For infrared transmitters, you'll need a direct path between the headphones and the transmitter. Placing the transmitter on or near the TV will allow you to take advantage of the clear path you already have.
Plug in the transmitter and turn it on. Charge the headphones if necessary.
Turn on the headphones. Adjust the volume and settings and you're ready to watch TV.
Wireless headphones that utilize radio frequencies often have a wide range but may suffer from interference from devices like cordless phones and microwaves.
