the price is a good start. around $60 with shipping for headphones that normally go for $150 without shipping.

number 2. - the color of them is off, where the rotate-able joints are, they are clearly the wrong color, they should be silver not black

number 3. - the headband is off, there is to much plastic where more cushion should be

number 4. - there is no stereo/mono switch

number 5. - there is no screw on adaptor for 1/8th to 1/4

if you go on here http://www.pioneerprodj.com/gear_hdj1000.html and compare the real to the fake ones on ebay.

dont be fooled. i wouldnt pay more than $30 plus shipping for theses fakes. i have even seen some of these fakes go for $100.

the fakes are replicas of the american audio hp700's
