Koss, a maker of high fidelity stereo headphones, earlier this week unveiled a new full size professional headphone model. The new Pro4AAA Titanium is priced at $149.99 and looks to be available now.

The Koss Pro4AAA Titanium (T), said Koss, features titanium coating on 2 mil mylar diaphragms for a frequency response of 10-25,000 Hz. These headphones have closed ear cushions made of a vinyl like material which reportedly provide improved sound isolation and maximum bass.
