1. The sound of the headphones is unique, ups and downs are reproduced well, no noticeable distortion
(That one for 20, - can not expect a perfect sound experience to an opera, should those who have given negative reviews are clearly such people to please 200, -. Spend on a headset if it's worth it to them the sound. This headset is definitely spotless)
2. The microphone transmits the voice clear and undistorted, optimally both for Skype's as well as games. It can also turn off unnoticed by switch, thus it will be no sound in conversation.
3. The seat is comfortable, you can therefore also work longer. In the beginning it's like some shoes: If it bears very long (> 5 hours), press the earpieces if it is new, maybe one or the other a little bit, but if it is only registered, you realize nothing. Believe me, I've already the second. ;-)
4. Unlike other headsets, the ear cups attenuate ambient noise, but you get something from the outside world with. It's not like with some other headsets, whose damping is downright, indeed, "sick" is, I'll call it.
5. The price / performance ratio: This much headset for so little money, even if that headset again holds "only" 2 years, it was worth every penny and is probably my next headset again this or any successor thereof.
