Part impractical, ugly and damn good.

I have the headphones for a few years in use. I had bought this mainly for use while jogging. It takes quite until you have bent the bow in the right position. And even if you have found a good position, the headphones pain after 2 hours. But for this you have great advantages:

++ Very good, full sound. Even low-end are well displayed.
+ You get ambient noise very well with (for the environment but also what is being played).
++ Keep forever (!).

- Ugly.
- Support structure used to (although competitors have nothing better to offer).

I had some competitor products in use and keep coming back to the KSC75.
