Not suitable for sport

The conclusion anticipate, for those who do not want to read everything:
For high-motion sports (ie everything except chess) not suitable because every touch of the cable is transferred to the headset. So not listening pleasure is possible. The problem now is not JBL specifically, but I had a pair of headphones from Philips (Philips SHQ3200 / 10), who had not the issue. There is no clip to the cable at the T-shirt to attach (if this would fix the problem, is another matter), thus the cable rubs with every movement of the clothes and this frictional movement is 1: 1 to the earplugs. It's frustrating ...

Now in detail:

Accessories:
There are provided two more essays that are supposed to fit each for the left and right ear in size L. For instructions on how to replace exists. There are also good explanation videos on YouTube to it. Just looking.
Plus, there's a small bag with a zipper, where you can stow your headphones well. I prefer here another solution, such as Apple or Bose, where the headphones are well involved, so that they can at rausholen quickly and easily, without having to untie use. Here can still be improved.

Quality and processing of headphones:
In elegant black (there are also in white with light blue and white with pink) do not fall on the headphones feel very valuable. The essays on Twist and Lock function are of a rubbery material, which assumes immediately dust. Probably silicone. Feels not bad, neither in his hand still in my ear. Both headphones have to sit on the drivers magnets that can be used to connect the same and it therefore can hang around your neck sometimes without them falling off when moving. (I put my headphones, model as simple under the T-shirt up and then they can sometimes dangle from the neck opening, goes well)

Sound:
Nothing special, because my upshots from above but still clouded, unless I'm sitting motionless around. Since then I suppose but rather a few high-quality headphones that need not be used for sports.

Packaging (design, material, feel, etc.):
You get the good headphones from the box, no problems here.

Conclusion is already up, my recommendation: Stay away, here you just annoyed. And for those who think that all headphones transmit the cable noise, which is not so. It is definitely better and that even for less money.
