Adorama offers the Beyerdynamic DT770 Pro Over-Ear Headphones for $145. A $25 mail-in rebate cuts the price to $120. With free shipping, that's $10 below last month's mention and the lowest total price we could find by $60. These semi-open studio headphones feature 250-ohm impedance, a 5Hz to 35kHz frequency response, single sided cable, and gold-plated jack. Deal ends March 28.
