VMInnovatios offers the refurbished Sennheiser HD-201 Professional DJ-Styled Headphones for $19.99. Coupon code “SAVE7″ drops it to $12.99. With free shipping, that’s $12 below the lowest total price we could find for a new pair today, although we saw new ones for slightly less in March. These headphones feature circumaural earpads, 3.5mm and 6.3mm connectors, and a 21Hz to 18kHz frequency response.

Note: A 90-day VMInnovations warranty applies.
