Dealzmodo: Trade In Old Crusty Headphones, Get $$$ for New Sennheisers

Are your headphones "broken, crusty or damaged" or just plain suck? Swap 'em for a pair of new Sennheisers. They'll take your old set in pretty much any condition, and will give you $5 toward earbuds, $10 for classic, $15 for in-ear and 25 bucks for noise-canceling headphones in exchange. You've just gotta mail in the linked form before Aug. 31. It's not a bad deal, I really liked their PX-100s for the price, and that was without an extra 10 bucks off. [Sennheiser (PDF) via Gearlog]
