Tanga offers the refurbished Bose QuietComfort 15 Noise-Cancelling Headphones, model no. QC-15, for $214.99 plus $4.99 for shipping. That's $49 under the lowest total price we could find for a new set. They feature 35 hours of of playtime via a AAA battery, detachable audio cable, and fold-flat ear cups for storage.

A 30-day warranty is included, but it's unclear who backs it.
