Beware the Sony MDR-7506HD and 7509HDs on Ebay from China at a very low price: suspecting that these were fakes, I bought a pair for a ridiculously low price from some chap in China and although they arrived promptly and were in a convincing box, once unpacked, it became rapidly apparent that these were indeed knock-offs. Terrible sound, left and right reversed, strange coiled cable, slightly out of kilter labels, no carrying bag, no warranty card and, once opened to correct the L/R swap, wrong drivers (genuine Sony drivers have three solder pads, these had two, poorly soldered, with the common wire floating around and insulated with a piece of masking tape.) After a short argument and opening a dispute with the vendor, I got a full refund, but the guy has so far failed to provide a return address, so I still have them. I suspect that people are buying these and then selling them on in the UK and the USA as genuine, so follow the old adage, if it looks too good to be true, then it almost certainly is.
