Is unstable at small ears

I have quite small ears (height: 1.70 m), and this headset does not sit firmly at me. As I turn it and turn, I do not get out that the headset rests without wobbling or slipping even. The rubber strap is too big and too flexible. He can not be ascertained, and when I almost put him to the ear, it goes by itself back to a looser position.

About all other aspects I can not say anything bad. The voice quality is fine, the operation simple, the weight is very low, the price as well.

Presumably one would the headset no longer notice after a while, if it were as tight. But this is unfortunately not the case. In the end, I can move my head very carefully, because otherwise the headset in place. Relaxed conversations are therefore simply not possible. This instrument will disturb.
