Massdrop offers the AKG Pro Studio Headphones, model no. K553, for $119.99 with free shipping. That's $20 below our mention from last week and the lowest total price we've seen. (It's a current low by $79. Other merchants are only offering preorders at this time and don't expect to ship the headphones until May; these are estimated to ship in mid April.) They feature a frequency response of 12Hz to 28kHz, closed-back design, foam ear pads, and 10-foot straight cable. Deal ends April 4.
