Among devices equipped with the connector, it is more commonly located at the bottom (charging port side) than on the top of the device.
Simplified graphical depiction of active noise reduction. To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control.A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds.
