$37.99 for Opus BT-C3100 V2.1 with OP3100 ( clearance) & $38.99 for Opus2.2 without using the coupon @GearBest

Apparently its a 3100 v. 2.1, with exclusive numbering for one supplier. So apart from the number, nothing. Theres a post here somewhere reagarding it, but Henry Xu was contacted, as yet I havent seen an official response from him regarding the 3400, nor can I find any official mention of a 3400.

Edit: Difference between Opus BT-C3400 & BT-C3100 v2.1?
