Bought Xiaomi Piston 2 from Geekbuying, not sure if they are original (pics attached) topic

Hello,

I bought Xiaomi Piston 2 from Geekbuying. Received them today and I'm not sure if they are original.
The inner part of the cone that connects the wire to the earphones has the letter L or R in embossed black (not orange/brown like mentioned in some forums).
The outer part of the cone has embossed "mi" logo.

They sound OK.

Are they original?

Thanks
