Ending today, Groupon offers the Monster Beats by Dr. Dre Studio Noise-Canceling Over Ear Headphones in Orange for $184.99 with free shipping. That's the lowest total price we could find by $15, although we saw them for $5 less last week (since expired). They feature active noise cancelling (powered by two AAA batteries, included), a detachable cord, audio adapter, carrying case, and in-line remote and mic.
