Reply to: at biz4ry@veretekk.com There are two categories of wireless headphones: those for use at home (often used for watching TV); and those you use with portable players and cellphones. In both cases the signal can be transmitted through the air a number of ways. Infra-red systems use invisible red light like a TV remote control; they are limited to one room and to line-of-site, and typically suffer from poor signal quality. Systems that use radio frequency (RF) are usually 900 MHz FM analog transmission and can usually reach throughout a typical home; however, as you get farther away from the base station transmitter you'll hear more "hiss" in the audio. The clearest and best sounding wireless systems use 900 mHz FM digital transmission. When you are in range the audio will be crystal clear, but when you begin to go out of range the signal will begin to turn off and on. Wireless Headphones Click here for more links |
