Focus Camera offers the Beyerdynamic DT 1350 Closed Supra-Aural Dynamic On-Ear Headphones for $89.99 with free shipping. That's tied with our July mention as the lowest price we've seen. (It's the best deal for these headphones now by $60.) They feature an 80-ohm impedance, 5Hz to 30kHz frequency response, swivel ear cups, and gold-plated jack.
