Balanced wiring for Sennhesier 800 S

I've used Forza Audio Works and Norne Cables with great results. Both should have many options for different cable options, termination choices, maybe even colors, so you can find something to fit your budget.

Sennheiser makes a high quality balanced cable for the 800s.  I have one and use it with the 800.  It's a good cable.  Works on the 800 and 800s.  

The Ayre QX-5 Twenty uses two connectors for balanced. Lavricables is trying to learn the Ayre wiring scheme.

Gotcha. The Cardas Clear cable is very nice. I have one with dual XLR for my LCD-4.  I think it's the best build of any headphone cable I have.  They use two cables and you can just order dual XLR with the right connectors for Sennheiser 800 / 800s.  Nothing to "try to learn".  Check out Moon Audio.
