As one of its daily deals, A4C offers the refurbished Beats by Dr. Dre Tour In-Ear Headphones in Black or White for $39.95 with free shipping. That's $35 under the lowest price we could find for a new pair, although we saw them new for a buck less a month ago. They feature a built-in mic and noise isolation. Deal ends today.

A 90-day A4C warranty applies.
