I'll post some impressions on the excellent Sennheiser HD650s here if anyone is interested as they break in a bit.
In the mean time, for the price, I am impressed with the quality packaging/box, the 1/4 to 3.5mm quality adapter that comes with them and Sennheiser's overall dedication to authenticity and quality.
Evidently there are quite a few FAKE headphones out there these days. I don't know which brands are targets for this disgusting practice but if you buy a pair of Sennheiser headphones, you can go to
http://qr-sennheiser.com and check their authenticity. There is a holographic sticker on the box with a unique code. By inputting the ID of your purchased headphones, the Sennheiser site matches the ID with what is supposed to be on that hologram. Of course having purchased through Amazon, I was not in the least bit worried and of course the Sennheiser website confirmed it is an authentic pair.
I also purchased a Quadira Headphones stand from Amazon for $22.98. Looks good, matches my walnut Salamander rack.
