Yeah . I got the originals. I know that much from the sound quality . .
Also because the same guy was selling the cheap ones for 150!
As far as sennheiser is concerned i went for the cheapest model (in ear type) which was around 500 bucks.
The other neckband types were amazing but were all above 1.5k.
As for n73 everywhere in national market it is out for 22k. Ofcourse in grey.
P.S. Also the e50 arrived yesterday. Very slim and sleek phone. Priced at 15k
