I got this from INSHOES regarding the fake Piston 2.0. I wonder if the distributor gave him fakes without him knowing it, since many have bought from him and received genuine ones.
"I am shock that you have not contacted us before, then opened this dispute and simultaneously gave us negative comment. We sold this same earphones over 100 pieces on eBay. How comes you guess it is fake? I found you had been selling the similar earphones on ebay. Your feedback is impacting my business but i don't think you will get any benefit. I dare say it is 100% original. Anyway, as we describe on ebay, we accept return if you are not satisfied within 14days. I'll issue you the full refund via PayPal once I receive your parcel. Any damages not reported prior to return will be purchaser's responsibility and may be subtracted from total refund amount. We are not liable for any damages or losses in transit to the return address. i.e. pack it well and send fast & safe." If you have any problem and question, please email me. I will reply your email even in the period of chinese new year. Sorry for my poor english! Regards, CHENG"
