The sound of the headphones is good. I tested the headphones with different styles of music and I felt it so that he does not slip up.
Music listeners who are looking for a headset heavy bass music can properly represent sick here is more than find. This is really brutal!
Also, I can test it on different devices and have to say that he has been consistently good belongs.
Conclusion: good product at a fair price! The only thing that irritates me that no German-language instructions included was there.
