Learn About Wireless Headphones and Transmission Types
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.
Cell phone, iPhone, and portable player wireless systems also use a number of different RF transmission methods. Bluetooth wireless is very common in cellphone headsets and is good quality and essentially noiseless as it uses a digital signal scheme; however, current Bluetooth implementations do not transmit CD quality signals. There are a few wireless products that use the KLEER™ full CD resolution digital transmission scheme and can sound quite good.
Reviews Of The Best Wireless Headphones For Home
A long time favorite 900 MHz analog wireless system is the Sennheiser RS180, which utilizes a sealed headphone and numerous features to improve your movie and music listening. The less expensive Sennheiser RS160 are also good price performers with fewer features. The best sounding wireless headphone system we've heard is the Sony MDR-DS6000, which uses a digital transmission scheme and has a number of sweet features like digital audio inputs, Dolby Digital and Pro Logic decoding, and audio compression for better speech intelligibility.
