Adorama offers the Beyerdynamic DT990 Professional Over-Ear Headphones, model no. AMS-DT-990-PRO-250, for $155. This $35 mail-in rebate drops it to $120. With free shipping, that's tied with last month's mention as the lowest total price we've seen. (It's a current price low by $67.) Features include a 5Hz to 35kHz frequency response, 250 ohms impedance, 3.5mm gold-plated jack, and 1/4" adapter. Rebate ends March 24.
