Found this one after my last headphones/headset started cutting out in one ear. I found the price via a StaticIce search and it seems like it's the legit product and not just an adapter or replacement part. I was thinking of going a decent headset from Audio-Technica, Sennheiser or something in that range, but for $12 I've ordered a couple of pairs (one for backup?) and will see if they get delivered.
They retail for $89 at PC Case Gear and $99 at JB Hi Fi
