The sound was good if you do not move. Once movement comes into play - walk or similar - you constantly hear muffled noises with every step - No, not the steps, but some electronic noise on the part of the headphones) -.
But what was even worse, is the processing
Looks at first sight first cool. My first impression was great. However, the bear has ever scratched something on the ear. The problem I had with any of my in-ear headphones. At closer inspection noticed that the welds (guess with plastic is the other - Verklebungsnähte?) Were processed unclean and have this by disrupting incessantly.
Conclusion: For the price I would have expected more. I should return the thing in time. Now it vermordert somewhere in my room and will one day provide as part of my heritage for scratching the ears of my grandchildren yet
Definitely not advise)
