First: the price they are definitely worth (!).
- The presentation is nice and stylish packaging. The beiligende pocket accommodates from now my player (Sony NWZ A818) including the new headphones.
- The cable is long enough and pleasantly thick, which is hopefully synonymous with hard-wearing. In the upper part it is divided symmetrically. I think that's better than the asymmetric division, where you have to run around the back of the head a cable ever.
- The plug is gold plated and slightly bent - thus the cable end is not so strained by the typical Rumwickeln to the player.
- The ear pieces are available in three sizes this: S / M / L. I have always had M, but here I was initially disappointed with the sound (especially bass), also they were not really fixed. Then I switched because of size L and see: Great sound, good bass and it stuck. So: Only with proper seat they also develop good sound!
In this respect, I do not know why you should advise the product. The value can be described as very good.
