Rf headphones are using a stereo frequency modulation system when transmitting sound from transmitter to the headphones. It is pretty much like having a mini radio station in your house. These kinds of headphones are perfect for TV, computers, games consoles when you don’t want to disturb people around you.  The range of an rf signal can be affected by other sources and some materials used in building construction. The newer headphones are a lot less sensible for interference from example microwaves and other devices then the earlier ones. Radio waves are the best choice if you’re looking for total freedom.

There are also wireless headphones that use light to transmit the sound. This technology is called ir, ir stands for infrared. The disadvantage using ir headphones are that they only work when the light is visible. That means that you have to make sure that it’s always open air between the transmitter and the headphones to get a clear signal.
