- The earcups that could turn are totally distorted by the many touchdown, which means that they no longer sit properly stable on the ears
-The Sound quality has extremely weakened, on the left headphone music was accompanied by a noise.
- The '' package '' of mini boxes are dropped, they must therefore put no shell in the ear, which is quite unpleasant.
These shortcomings have prompted me to purchase other much more stable headphones. Unfortunately, a bad buy.
