Planar magnetic technology is a type of headphone design that uses a thin diaphragm suspended between two sets of magnets. This diaphragm is typically made of a lightweight material, allowing it to move freely and produce sound when an electrical signal is applied. The even distribution of magnetic force helps create a more accurate and detailed sound reproduction compared to traditional dynamic drivers. These headphones are known for their wide soundstage and low distortion, making them popular among audiophiles. Brands like Audeze and HiFiMAN are well-known for their planar magnetic headphones, which often provide a rich listening experience across various music genres.
