The headset comes in a tidy, quality plastic case with side zipper.
If you open this you will find of course the headphones, two cables (very nice:. A wired remote control for mobile devices, as well as a classic headphone audio cable) as well as an adapter from small to large jack.
Processing:
Since there is nothing to complain about, everything makes a very good, stable impression. Fits comfortably, even after prolonged wear not pleasant. Socket sound on the headphones, or wobbles as creaks nothing, switches behave as stable and normal.
Sound:
Probably the most important. From my side no complaints as the previous speakers have said, give the headphones a few hours time.
From sound wise, it is clearly Koss and I like it. Clear, slightly accentuated, pure music. If you want to compare, it is the sound of her rather than at Marshall at Sony (I think) and again here is not about quality but about the sound.
Conclusion:
Outstanding for the price. I'm excited.
