Product Review
The Koss Pro-4AA stereo headphones were built with studio and broadcast use in mind. Closed-ear cushions provide excellent isolation and bass, while high and low sounds come in clear due to its 10 to 25,000 Hz frequency response.
The Pro-4AA includes microphone mount hardware, 0.25-inch plug, and a coiled, single-entry 10-foot cord.
