Features:

• 10 - 25,000 Hz frequency response

• 10 foot cord


• .25-inch plug

Koss UR20 Stereophone, Dynamic Element for extended frequency response Closed leatherette ear cushion for maximum isolation and deep bass. Built for maximum durability for DJ and recording use Straight, single entry 8 foot cord - Black - Mini-phone stereo 3.5 mm connector This full-size professional quality stereophone has long been the headphone of choice for broadcast and recording professionals whose careers demand reliable equipment and superior performance. As the first dynamic stereophone to deliver true full frequency, high-fidelity performance, the PRO4AA set the standard when it was introduced in its original form in 1970. In the late 1980s after long service, it was retired and replaced by a newer model. Customers clamored for its return, and by 1988 it was brought back by popular demand. Since then, though we've incorporated performance-enhancing technology and updated its style, the essence of the PRO4AA remains unchanged and it continues to set the standard for performance and reliability today.
