Sonic Electronix via Rakuten Shopping offers the refurbished Sennheiser Momentum Over-Ear Headphones in Black or Brown for $134.95. Coupon code "MOMENTUM" cuts the price to $119.99. With free shipping, that's $30 under last month's mention of a new unit and the lowest total price we've seen. (It's also $47 below the best price we could find for a new unit today.) Features include 110db sensitivity, 16Hz to 22kHz frequency response, 18-ohm impedance, and iPhone-compatible cable with remote and microphone.

Note: A 2-year warranty applies, but it's unclear who backs it.
