Not sure, it could be VSonic's mistake. The box was so light, I could feel something was wrong even before I opened it, GR07 bass edition and carry case will add some weight even though they are small.
when first shipment was lost in transit, response from lendmeurears.com was quick. Even though there was two weeks delay, they sent one more package, but end up having no headphone in it.
waiting for their replay, I may get GR07 eventually, but Amazon or local warehouse would be quicker and much safer.
