The Koss UR40 is an ultra-lightweight, full-size over-ear headphone that delivers heavyweight sound intensity in a portable, travel-friendly design. Featuring a unique hybrid construction, the UR40 combines the immersive bass response of closed-back headphones with the natural, open soundstage of open-back models.
