Two pins are used for the mono headphone signal and two pins for the unbalanced microphone signal. The 4-pin XLR connector is also commonly used on amateur radio microphones, but transferring unbalanced audio instead, and using the 4th pin (with the common ground) for a push-to-talk (PTT) circuit activated by a button on the microphone.
Simplified graphical depiction of active noise reduction. To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control or ANC.A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds.
