What Are Wireless Earphones?
Wireless earphones allow the wearer to listen to music, computer or television without the use of speakers or wires connecting them to the output source. There are three different types of wireless earphones that are available to meet consumer demand. Wireless earphones require a transponder and a receiver in order to process the sound. The most common method of transmitting the sound waves are radio, infra-red and Bluetooth®. All of these technologies perform the same basic function, converting the signal from the output device to anther format and transmitting it to a receiver, embedded in the headphones themselves. The received signal is translated into the sound the listener hears. Radio wave-based wireless earphones are usually over the ear models with a large base that must be plugged into the source of the sound, using an audio plug. The wireless earphones are activated when they are put on over the crown of the head. The signal is transmitted using radio channels. Interference
