I bought these to replace the Westone cable that came with my ES60.
In terms of ergonomics this cable is better in virtually every way. The shape/size of the connectors is better, and the cable itself is more supple. This has eliminated 90% of the microphonics issue I was having with the stock cable. The cable feels more premium.
I've always been skeptical about cables making a big difference in sound quality, but I believe this cable has led to higher volume levels at the same point on the pot.
