Released May, 2003
The Pros:Looks epic. Manufactured with good material, and seems to be really durable. Good Frequency response, but not the best [10 - 25,000 Hz].
The Cons:Can be heavy to ears. Not good for DJ works that you need flexibility.
The Koss PRO4AA is a full-sized professional-grade stereophone which, according to Koss, is the headphone of choice by broadcast and recording professionals. The stereophone features dynamic elements for a wider-than-average frequency response and a titanium coating on its diaphragms to provide reinforcement, reduce distortion, and improve sound performance.

It is designed with closed leatherette ear cushions that coddle the ears, isolate external noise, and enhance bass as well as a steel and rubber headband with padding and adjustable slide bars for a comfortable fit. The PRO4AA has a heavy duty 8 ft coiled cord with a 6.3 mm gold-plated adapter and comes with a lifetime warranty. Compared to Koss' PRO3AA stereophone, the PRO4AA has a wider frequency response range and higher impedance. It also has a 6.3mm plug compared to the 3.5mm plug + 6.3mm adapter of the PRO3AA and includes microphone mounting hardware which the PRO3AA lacks.
