Difficult for small ears

The sound is absolutely great. Just as already mentioned a bit much treble. But otherwise a very clear listening experience. The stopper also seal well, so you can shield the ambient noise well. As commuters by train which is very helpful.
The only drawback: The pegs keep me wrong, because I can set far enough into the ear even with the smallest essays not. I have rather small ears and the plugs for this are simply too thick. In normal ears but it should not be a problem.
