Many moons ago developers and researchers discovered that radio waves could in fact be leveraged for more than just radios. RF technology thrived during the 40's and 50's due to World War II and the industry grew at a fast rate because of continued military application. It took several decades for the RF technologies to really take root in the market place. It wasn't until the later part of the 1980's that wireless markets finally took root.

Truth be told, this technology has been in use for a long time in the medical and industrial markets, and will play increasingly essential roles in industries like automotive engineering. This stuff has been around for a while now and finally, it has made its way to our homes with sweet wireless TV headphones.

RF (Radio Frequency) wireless TV headphones usually operate in the 800-900 MHz band. With Radio Frequency technology you have the ability to keep your headphones and move from room to room if you want and only need to use a single source for your audio output. This is possible because radio frequencies can travel through walls.

RF however loses quality during the transmission. The frequency needs to be modulated into one frequency and then demodulated at the headphones to create the stereo sound effect. The modulation process obviously messes with quality by adding extra steps to the process.

You need to remember that any wireless technology will be prone to interference and even complete signal loss. Interference can be cause by any number of other devices or frequencies in proximity. From wireless phones to wireless internet to gaming devices; any of these can cause interference and static especially if they' re on the same frequency.

Signal loss on the other hand is caused by a weak or lost transmission. This too results in static, poor audio quality, or loss of sound altogether. Signal loss is due to one of two factors. Either the distance from the transmitter to the receiver is too far for a clear strong signal to be received by the headphones, or the signal is being "blocked" in some manner by obstacles.

The two main culprits of RF blocking are water and metal. Radio frequencies cant penetrate metal and you'll often find protective metal firewalls in buildings and sometimes in homes. Water usually isn't an issue since most people do not have walls of water... however people are made up of a lot of water so if ,for instance, some stands in-between you and the transmitter you may experience some interference.
