Tanga offers the refurbished Beats by Dr. Dre Studio Noise-Canceling Over-Ear Headphones in four colors for $108.99. Coupon code "BEATS" yields free shipping. That's $70 under the lowest total price we could find for a new unit, although we saw them new in April for just $5 more. They feature active noise cancelling (powered by two AAA batteries, not included), a detachable cord, collapsible design, and in-line controls. Deal ends today.

A 30-day warranty applies, although it's unclear who supports it.
