The sound is compared to the PC-151, which I had, somewhat less precise in the deep bass, but a little clearer in the centers. Broadly neutral, with no significant coloration, so that you do not "fed up listening to."
It is a closed system, you can hear from the outside world and even their own little sound muffled discolored. This may be desired, I find it rather disturbing.
Unfortunately, the pressure on my mind is so brutal that I get pain in the ears after a quarter of an hour. Stretching brought no improvement even after one month. Therefore, the depreciation on a star, it is effectively unusable for me.
Who plays with the idea of it to pick up, it should definitely try before - but a specific head size (not too big the turns), it is no longer acceptable.
