Sorry for the thread revive, got a question, Would you recommend buying from this place? I'm looking at the Sony MDR-XB90EX's:

That seller looks alright, sold 9 of them so far, I asked him about warranty and he said its only valid in Japan, accessory jack says i'd have to post it back to them in the event of a issue.
Edit2: I emailed Accessory Jack asking about the condition of the item and warranty.
"Thank you very much for your inquiry. yes, everything we are selling is genuine and 100% brand new. So no worries. Warranty is 1 year effective in Hong Kong. So if there are any problem, you can simply send it back to us and we will pass to Sony for official warranty here. Please also keep the box with you as the official warranty sticker is there."
I think i'll get it from them, the ebay seller said the warranty is only valid in Japan, didn't say I could return it to him in the event i have a problem.
