BuyDig offers the Audio-Technica ATH-R70x Pro Reference Headphones for $299. In-cart, the price drops to $199. With free shipping, that's $25 under last week's mention, which was bundled with a $25 Newegg gift card (still live), and the lowest total price we could find by $150. These open-back headphones feature 45mm drivers, a detachable 10-foot cable, 470-ohm impedance, and a frequency response of 5Hz to 40kHz.
