Focus Camera via Newegg offers the Sennheiser HD600 Headphones, model no. 4465, for the in-cart price of $254.99 with free shipping. That's the lowest total price we could find by $44, although we saw them for $5 less two weeks ago. They feature a Kevlar reinforced 3-meter cable, 300-ohm impedance, and a 12Hz to 39 kHz frequency response. Deal ends February 12.
