Planar magnetic drivers are a type of headphone technology that uses a thin diaphragm suspended between two sets of magnets. When an audio signal passes through the diaphragm, it moves in response to the magnetic field, producing sound. This design allows for a more uniform sound distribution and can result in clearer audio reproduction. These drivers are known for their ability to deliver a wide frequency range and low distortion. Unlike traditional dynamic drivers, which rely on a moving coil, planar magnetic drivers provide a more consistent performance across different volumes. This makes them popular among audiophiles and professionals in the music industry.
