Designed for immersive listening and built to handle the rigors of daily student use, the Koss UR20 Full-Size DJ Style Headphones are a dependable choice for classrooms, media labs, and distance learning. These over-ear headphones offer exceptional sound isolation, a durable build, and the comfort needed for extended lessons or test sessions.
