2 attempts disappointing

On the second day did not work the headset. I was barely audible, loud crack and noise on the line. I went, after so many good reviews here, from a rare product defects and exchanged to. The second headset allowed after less than four weeks before any more talks go on. And, although I really care so Bypass and it did not often used. Even at home, I had to make calls without a headset - it sounds as if I were behind sheet per knistere with paper. Very bad!
