http://lendmeurears.com/product_info.php?currency=USD&cPath=13&products_id=143 is an authorized seller of Vsonic. That's the real bass version, so you don't have to worry.
edit: Also, I saw that in another thread you were worrying about the plug - it comes with J-plug unless Vsonic changed the plug in the last batches.
Thanks for the quick reply.
Yeah, it seems there have been some revision of the model in June from J to L-plug. Well well, a J-plug would certainly have been much better.
