What is Radio Frequency? Radio Frequency transmission works by sending our
radio frequency signals from the transmitter to the headphones. Radio
frequency signals allow high fidelity sound reproduction and have a large
reception range that does not require keeping the headphones within line of
sight of the transmission. Radio frequency signal quality can deteriorate
due to external noise and interference in some settings.
Sound Neodymium magnets give you a high fidelity, FM stereo sound
reproduction.
Design Comfortable fit with adjustable headband and complete coverage of
the ear.
Battery Supplied rechargeable nickel-metal hydride battery automatically
charge by placing the headphones on the transmitter base station;
headphones charge via electromagnetic induction charging.
