Harman Audio offers the factory-refurbished Harman Kardon NI Sophisticated Earphones in Black/Silver, model no. HARKAR-NI, for $69.99. Coupon code "15HKNI" cuts it to $15. (The discount may apply automatically without the need for a coupon code.) With free shipping, that's tied with last month's mention and the lowest total price we could find for a refurb by $22. They feature three pairs of silicone sleeves, inline controls, a 3' 8" cable, and carry case. A 1-year Harman Kardon warranty applies. Deal ends March 22.

Update: The price now falls to $13.50 after coupon.
