As a reader discovered, BuyDig via eBay offers the Beyerdynamic DT 880 Premium Headphones, model no. 483931, for $139 with free shipping. That's $20 below our November mention (which included a $50 Newegg gift card) and tied as the best outright price we've seen. (It's a low now by $50.) They feature a 5Hz to 35kHz frequency response, 32-ohm impedance, gold-plated 1/8" jack with 1/4" adapter, and carry case.
