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.

The UR20 features a closed-back design with large leatherette ear cushions that surround the ears for passive noise reduction — perfect for minimizing distractions in shared learning spaces.

Its 8-foot straight cord gives students flexibility at their desks without pulling or snagging, making it easy to move between devices or stations.

With a standard 3.5mm plug, the UR20 works seamlessly with desktops, laptops, media carts, and most school audio equipment. Whether you're outfitting a computer lab, supporting student creativity with music and video editing, or building out a remote learning station, these headphones deliver reliable performance at a student-friendly price point.
