Great question...and one I didn't think to ask. Unfortunately, if you buy the refurbished from Best Buy (Geek Squad Certified or not) you may NOT purchase AppleCare for these (or any other refurbished Apple product for that matter). Best Buy told me originally I could buy Apple Care for these, but had to do it directly from Apple. When I took them to the Apple Store (2 weeks after the purchase) Apple told me they won't sell AppleCare on refurbished products, regardless how new, other than those they sell refurbished directly from Apple. So know, if you buy these headphones refurbished, you are not able to "insure" them through Apple Care.
