You can skip ahead to the sections of this article that explain these carrier waves in more detail by clicking the links in this paragraph. The carrier waves used to transmit wireless headphone signals are either in the radio frequency range or the infrared frequency range.

This modulating signal is encoded into a carrier wave that is transmitted wirelessly to the receiver. The intended audio signal is referred to as the modulating signal. Transmitters effectively encode the audio signal into a wireless format (the carrier wave) and propagate the wireless signal through the air. This “wireless signal” is appropriately called the carrier wave. Wireless headphones have built-in receivers designed to accept the wireless waves that carry the audio signal intended to drive the headphone drivers.

Connecting Wireless Headphones To A TV, Radio, Or Other DeviceĪs the name suggests, wireless headphones receive their audio signals wirelessly rather than via headphone cables (often referred to as “hardwired” headphones).
