The headphones make a good visual impression. But in my opinion are not original. The headphones that came with the grade 3 had to fix this slider to adjust the lines upwards together. Acoustically these in my opinion are also at a disadvantage here. The originals have a richer bass and better dynamics and sound balanced.
That although many vendors weighed so that me does not happen just that here as well, this product is no real original goods.
