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.
