Replacement ear pads are cushion-like accessories designed to fit over the ear cups of headphones, enhancing comfort and often improving sound quality. Typically made from materials like memory foam, leatherette, genuine leather, or velour, they provide a soft barrier between the hard structure of the headphones and your ears. Memory foam ear pads, for instance, mold to the shape of your ears, offering a snug fit that also helps with noise isolation. Leatherette ear pads tend to offer a sleek look and are easy to clean, while velour pads are breathable, making them ideal for extended use.
