The sound of the headphones is I find excellent for the price. They also sit with me (with the smallest essays) perfectly in the ear. If that would only remain so ... In my first couple went to 1-2 months of a headset no longer (only when I pushed the plug into my iPod in a particular direction). After Exchange unfortunately exactly the same. After 1-2 months of (time) other headphones no longer went. I often hear a've ichs first so left .. Strangely, the other works now no more (without interference) / he does not work with any device. I would so like to correct ineradicable headphones. Because of the break: I use the headphones as normal, but they often have at school in my shirt, what should endure headset but. Even so favorable.
