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 compared to traditional dynamic drivers. These drivers are known for their low distortion and wide frequency response, making them popular among audiophiles. Brands like Audeze and HIFIMAN are well-known for their high-quality planar magnetic headphones, which often provide a more immersive listening experience.
