Sonic Electronix via eBay offers the open-box Sennheiser Momentum Over-Ear Headphones in Black for $119.99 with free shipping. That's tied with our mention of a refurb from four days ago and the lowest total price we've seen for these headphones in any condition. (They're a current low for an open-box unit by $36 and $53 under the best price we could find for a factory-sealed pair.) Features include 110db sensitivity, 16Hz to 22kHz frequency response, 18-ohm impedance, and iPhone-compatible cable with remote and microphone.
