Adorama offers the Sennheiser HD600 Stereo Headphones, model no. 4465, for $239 with free shipping. That's $6 below last week's mention (although that was bundled with a $25 gift card), a current low by $21, and tied with the lowest outright price we've seen. They feature a Kevlar reinforced 10-foot cable, 300-ohm impedance, and 12Hz to 39kHz frequency response.
