The Microsoft Store offers the Beats by Dr. Dre Executive Over-Ear Headphones in Silver, model no. 900-00047-01, for $169 with free shipping. Outside of the mention below, that's the lowest total price we could find by $30, although we saw them for $10 less two weeks ago. They feature active noise cancellation (powered by two included AAA batteries), a 4.5-foot detachable cord, 1/4" audio adapter, and carrying case.

A close price: Newegg offers them for $169.99 with free shipping via coupon code "EMCWHPA35".
