Adorama offers the Sennheiser HD600 Stereo Headphones, model no. 4465, for $229 with free shipping. That's the lowest total price we've seen without a rebate, although we saw it $5 less after a rebate last week. (It's a current low by $43.) They feature a Kevlar reinforced 10-foot cable, 300-ohm impedance, and 12Hz to 39kHz frequency response.
