To make calls, the headset, at least from my experience, not to use.
My interlocutors complain all that they hear themselves. I'll be happy to be asked if I'd actually call from Timbuktu. In addition, the sensitivity of the microphone is obviously very poorly coordinated. By unavoidable ambient noise in the moving car to an understanding with the other party is also practically impossible.
Unfortunately, I had once bought the headset is not in the online trading, but with a dealer. A return was rejected for hygienic reasons.
Conclusion: Stay away! If I could, I would have awarded 0 stars.
