So I received my Cardas cable from "the eBay guy":
Not ready to make impressions yet since I've been busy with work.
One small thing that bothers me is the connectors have no way of locking when you insert them into the headphones. With the stock cables, you can push into the jack and twist so they're secure and won't pull out on accident. You cannot do this with these cables. I've tried twisting every which way and eventually stopped in fear of breaking something.
The connectors for the HD-700 do not twist to lock. There is a flat edge which must be aligned to insert.
I got one and I really hate this cable...
Does yours have this weird stiff coating on the bottom half?
I got one of those cables from ebay and its ok, no weird stiff coating on the bottom half, I've since built my own using Mogami and Canare wires so that I can make what ever length I want, HD-700 connectors are fairly easy to work with, and it becomes much cheaper in the long run.
