I can not say after 1 day on the durability of the headset.
If treated properly, but they are probably their service very well equipped.
The comfort is very good for my taste. Here there is no slippage, pressure pain after extended wear (retrospectively approx. 2 hours in
Bus + train for service), the earpieces are thanks to their ball-like attachment (in all directions movable), close to the ear cups.
One thing I had to learn, however, today morning on the train: A passenger (s) sitting opposite me, behaved strangely, probably heard
some of my music (I'm not a "sound listeners"). However, another test with my colleagues revealed no for them annoying, audible music history
noises (just a little hiss).
Conclusion: Clearly, there is room for improvement everywhere, but on the whole I can say to me: "These headphones are for this application (MP3, cell phone, etc.) fully managed".
