As one of its daily deals, Newegg offers the Beyerdynamic Custom i On-Ear Headphones for $49.99. Coupon code "EMCSRGRK4" cuts it to $29.99. With free shipping, that ties last month's mention and is the lowest price we've seen for this model. (It's also $50 under the best price we could find elsewhere, and a great deal for headphones of this type.) They feature a 5Hz to 35KHz frequency response, built-in microphone, and 16 design rings.
