why does everyone always mention their cable being made out of silver?
silver is only like 8% more conductive than copper, and considering how freakin' expensive it is, I doubt the cables are 100% silver. which means even if the cable is 50% silver, which i really doubt, that means it's only 4% more conductive than copper for a HUGE price premium.
the only things I can think of that a cable could improve, is to add shielding from noise, and keep capacitance down. but silver as the conductor? snake-oil!
but back on the subject: are there any non-gimmick regular cables for the hd650 out there that aren't 10ft long like the ones it comes with? I'm tired of having ten miles of cable on my desk.
You could check in on Ebay, contact this seller, he is a member here, and tell him what you want, and he may make it for you. http://www.ebay.com/sch/wjernst/m.html?item=111278048908&rt=nc&_trksid=p2047675.l2562 This is the one I bought from him August of last year and love it. Custom Sennheiser HD-580, HD-600 and HD-650 7 Foot Cable (#111149853321) never gets caught under foot, and the connector and cable look great..and for $49 dollars was simpler and quicker than a diy cable.
