Koss Pro4AATs are a new twist on legendary headphones. Getting their inspiration from the Koss Pro4AA, the Pro4AAT feature dynamic elements for an exceptionally wide frequency response. This fresh take on the long-time industry standard features a 2 mm titanium coating on its diaphragms for increased rigidity, minimized mechanical distortion, and exceedingly accurate sound reproduction. 

The modern look of the Pro4AAT will mean that you will not only hear amazing sound, but look good while listening. These lightweight Koss Pro4AAT headphones were designed for frequent use over extended periods and are perfect for professionals and audiophiles seeking to capture every note for a cleaner, clearer sound.
