I have just ended up with (purchased them thinking they were the real deal) what appears to be an identical set of fakes. Just a couple of extra points regarding them. The lead is long (claims to be 1.2m, but it is more like 6 feet, or 1.8m, just by comparing it to my height). The box has no audio-technica contact details on it, and no warranty details either (nor in the box). The head band feels squishy, and if you look carefully on the side of the chrome (where it is brushed metal on the real units), you will see some moulding marks (which makes me think it is a plastic casing). Sound quality, a lot less bass, and the highs were harsh and distorted (compared to an authentic set of ath-es7's, but this was from listening to the authentic item with only one side working, and me not being the worlds most critical listener, just know what I like).
As for where it was purchased from, it was ebay (I really should have known better).
