Harmful to health - Return shipping after a day

Lowlights:
- Status tones are harmful loud (despite very low volume levels)
- Noise suppression or reduction No
- Own voice is (at different times) when making calls replayed via headset
- Comfort there is not

Neutral:
- Satisfactory, you can classify the music playback

Conclusion:
Since the status tones (answer, play, stop, etc.) are much too loud, I can NOT recommend this Haedsrt. I advise everyone from before buying! Apart from wearing is a torment.
