A few things I think are notable:
1. Top notch service - I got one on one attention to make this work for me, so I didn't have to ship the headphones back and forth. Very much appreciated.
2. Quality workmanship - This 4 wire braid is very well done. Completely even start to finish. It looks really sharp
3. The wire itself - I'm not much of a fanatic for wire changing sound qualities. I think it does to some extent, but not to the point where its worth spending $300 on a cable for cans that cost $280. This cable made my K501 sound warmer and smoother overall. They had a sense of "texture" I've never heard from any headphones I've owned. I was quite shocked.
4. Speed - Very fast turnaround time, especially considering this was customized for me.
