Focus Camera offers the refurbished Audio-Technica ATH-T200 Closed-Back Dynamic Monitor Headphones for $14.99 with free shipping. That's $14 under the lowest total price we could find for a new pair. They feature 40mm neodymium drivers, adjustable double headband, gold-plated plug, and 20Hz to 22kHz frequency response.

A 1-year warranty is provided, but it's unclear who backs it.
