Here at Amazon saw the parts in the pictures really good and (relatively) high, and the (2) Reviews have been positive.
Today they have arrived (ordered yesterday, as always Top Shipping Amazon!) And they also go back today!
1. The packaging of KHS is absolutely cheap and totally fiddly to open.
2. Processing and haptic quality of KHS is about the same level of packaging. Etc. and not even begin with beats, sounds - all of the cheapest hard plastic compare, which also do not have too hohwertig.
3. It is advertised that the KHS "convenient" are. That's an insult! The ear cushions seem not even leatherette earcups and would possibly still so just large enough to enclose the ears when they would sit on the ears ... because pressure is also present in any way, which makes them also sit very loose.
4. sound quality (if one may call it that) is pathetic and about with my 3-ears of Hama compare.
I do not know how other reviewers awarded 5 stars and could talk about a good P / L ratio ... one probably for 10., But not for 50!
PS: As an alternative in this price range, one could even view the "Denon AH-D510R". Qualitatively even not a high flyer, but superior / Haptic sonically far and cheaper in price! Even better sound provides the AH-D1100, but is processed slightly more expensive and as bad, so ...
