Koss UR21 Headphones are ideal for listeners seeking headphones that have a big sound but are also comfortable and travel light. With their high quality sound performance and enhanced bass, these headphones provide great audio.

And as for comfort, an adjustable headband ensures the headphones fit any head size or shape. Plus the ear pads are cushioned enough to make even long listening sessions a pleasure, while they seal lightly around the ears to improve bass response, block outside noise and prevent sound leakage.
