Then your nearly smegged, same issue with any imports...
SIEA serial numbers will not be repaired by SIEE... Thats the issue with importing...
US CS won't ship out side US as there shipping deal is not valid for foreign countries ...
Youll have to risk Ebay and see if a seller has stepped on there headset and has a dongle that has been whiped of pairing details... (not sure they have worked out how yet this model may not be not old enough)
Theres a Fraud action which physical retail have been trying to fight with but have failed badly ..
Called switching items...
You by another from a physical store and then switch the Items... and refund... the only problem is many other people have been sending theres back since the headset released so the "NEW" one from retail could also be a switched duff unit resealed that the store is trying to flog off...
