You can trust lendmeurears, I got my GR02 Bass Edition from them in 3 weeks shipped from SG to US.
However, I do have a few issues with them.
1) They list their prices in SGD so when you check out with Paypal, YOU WILL BE PAYING MORE. Not sure if it's the same if you buy from their Ebay store. To be honest I felt ripped off paying 2 dollars more since I ordered through their website.
2) Their return policy could better considering how much some of the IEMs cost and they're made in China. Better in the sense that at least the IEMs should be tested before shipping to ensure they work. Since shipping them back from (wherever) to SG is going to be costly and will take a long time.
That said, will I buy more Vsonic from them? Yes. But if I can find a reputable seller in US through Amazon or Ebay I'd rather not deal with having IEMs shipped to me from SG.
