Racks4Server via Rakuten offers the refurbished Monster Beats by Dr. Dre Tour Noise-Isolating In-Ear Headphones in Black for $49.99 with free shipping. That's the lowest total price we could find for a refurb and $9 under our March mention of a new pair in a different color. (It's also a current price low for a new pair by $67.)
