I just purchased a set of pioneer hdj 1000's of eBay and when they arrived they were fakes. They are American audio hp-700
with the pioneer logo on them. A very similar look but a few minor differences. The sound quality isn't bad but the lows are horrible. They make a weird noise. They came from China and they were only $50. You can tell a fake from a real by the swivel joints, the fakes are black the reals are silver. Also there is no stereo/mono switch on the fakes. If the headphones are extremely cheap, come from china, and have a stock photo ask for a real photo of them or there probably fakes. I hope you found this review helpful.
