These headphones are too poor even for Chinese quality standards!
Cheapest plastic, poor quality!
After unpacking it rattled until the right speaker mussel loose, not verklebt-!
1 day later it rattled in the left speaker mussel loose, not clever verklebt-!
Then, when someone says "for this money you can not expect more ... wrong.
Had better already for 10 euros in the media market, held 2 Jahre.Klang better. So it is yet.
In addition: If you can not produce at such a price clever, you have to let it stop! Logical or?
A pig who sold something. Final inspection? Quality Control? None !!!
Want my money back, the scrap !!! you can pick up with me. I do not schick`s back costs else again my money.
With best regards
