Hey, they’re available from reputable vendors everywhere, as genuine. I like Buy.com, and the price is currently at about $37 with free shipping, just about an identical net price, and you can exchange them in a case of a problematic pair. The eBay link shows troublesome details, in my opinion.
Stick with a reputable vendor, and you’ll have a much happier (and safer) experience.
