Professional in the road, I have to be reachable at any time, this headset is so perfectly work without unwanted disconnections without background noise. By cons, mitigation microphone in noisy sound environment is a little too effective, because at times you can not hear me at all, copy to see that side. Listening side, this headset is really high quality sound reproduction. By against the part entering the ear is a little big and gives a gene printing after one hour. We are obliged to take the headset and thus risk losing. It's a shame, because the rest is of the highest quality.
