Conclusion: For this price you get here is a very good operating Bluetooth headset for hands free phone calls .. For listening to music, the headset is less suitable. The sound in music can then only a very limited rise joy.
Of course the price goes into my evaluation, the headset z. B. would cost 30 or 50 euros, I would rate it with 3 to 4 stars.
On the other hand, I had already had experiences with similar headsets in absolute low-price segment, ie around or below 10 euros. None of them was able to convince me. Of this headset is far away.
