Newegg offers the refurbished Sennheiser HD 25 Amperior DJ Stereo Headset in Silver for $99.99 with free shipping. That's $170 off and the best price we've seen for this headset. Features include a 16Hz to 22kHz frequency response, noise-isolation earcups, and removable remote with in-line microphone. Deal ends April 4.
Note: A 90-day warranty applies, although it's unclear who backs it.
