Fair price, good audio quality, fit is not optimal

I use this headset really only in the car, if I want to call without handsfree / needs.
Without problems Installation (pairing) with the smartphone was possible. The device is also recharged quickly. Battery life is very good for my needs, but I do not very often on the phone with them.
The price was really the decisive factor. The audio quality is good, I could understand everything well, and my opponent understands me well when driving.
Only the fit, or even the "stopper" for the ears is not really optimal. I wear glasses, it is true - but is already uncomfortable. The plastic, which comes into the ear would have better can be resolved - another material or a different shape, so I of mobile headsets seen better.
Therefore, 3 of 5 stars.
