Sharkoon Cosmic 5,1 revision 2

I would like to add myself a Sharkoon Cosmic 5,1 revision 2.
Can one determine somehow at the packing whether it concerns the revision 2?
If, where it stands? Or can one recognize it only on the basis the serial number?
If, on which I must respect there whether it is the revision 2. Starting from which Serienenummer go does Revision2 loosely?
On the homepage http://www.sharkoon.de/gerhtml/multimedia.htm#cosmic stands:
AGAIN: Specially padded Earpads for still better stretcher comfort
AGAIN: New microphone mounting plate for point-exact adjustment

But since I no comparison have, I thus cannot determine it.
Does someone have one taps?
