Hi. Was looking for any good deals on the KZ ZSN iem which were just released a few months ago. Got in contact with gearbest rep here who sent me this deal. Only 20 pcs, one per account.
Three colours, although purple seems to have the better cable.
Don't have any first hand experience but reviews seem very good.

Can be modded into wireless with Bluetooth cable, though am not sure which is best.
Why do these look like something Robocop would wear
