The wireless headphones can be used on both screens. The sound to the headphones is transferred from the screen via infrared signals (IR) to the headphones in two channel stereo format. The headphones are powered by an internal battery.

The headphones are switched on using a button on the side and the volume, in each earpiece, can be adjusted using a knob. The headphones also have a channel selector which controls the audio channel received by the headphones. The sound from the left-hand screen is always sent on channel A and the sound from the right-hand screen is always sent on channel B. A LED is lit when the headphones are switched on.
