The Sony MDR-IF240RK infrared wireless headphones are perfect for many different situations. Unlike conventional wireless radio signals infrared cannot be interrupted by electrical or magnetic interference. However, unlike wireless radio waves, infrared can also not pass through objects and walls. Infrared headphones must operate in open sight with no obstructions between the transmitter and the headphones. The Sony MDR-IF240RK headphones deliver crisp clear audio transmission through infrared transmission; allowing you to move freely about a room without worry of tangling or length. Perfect for listening to television late at night while others are sleeping.
They are also very useful for working out and listening to your favorite music wirelessly. If you have ever tried working out with wired headphones you are likely aware of the complications involved in using them. When you find yourself looking for a good sounding and dependable source of listening to any kind of audio, make sure you remember how nice these Sony MDR-IF240RK infrared wireless headphones are.
