BuySonic offers the open-box Sennheiser Amperior On-Ear Headphones in Silver or Blue for $94 plus $2 for shipping. That's $2 below our mention of a refurb from two weeks ago and the lowest total price we've seen for these headphones in any condition. (They're also $25 under the best price we could find for a refurb today and $232 less than buying a new, factory-sealed unit.) Features include a 16Hz to 22kHz frequency response, noise-isolation earcups, and removable remote with in-line microphone.
