Massdrop again offers the AKG K553 Pro Studio Headphones for $119.99 with free shipping. That's tied with our June mention as the lowest total price we've seen. (It's a current low by $5, although most stores charge $199.) They feature a frequency response of 12Hz to 28kHz, closed-back design, foam ear pads, and 10-foot straight cable. Deal ends August 11.
