Question
Does increasing db level damage the hardware?? What level everyone set for their 'headset' phone??
I tried the levels: 4 db (5fff) and 6 db (7fff). Both are pretty good; 4 db is loud enough to overlap traffic noise, not sure about train & subway; 6 db is EXTREMELY loud, my ear still ringing, for train and subway. I did not try 12 db but I m sure with the 12 db .. even a deaf can hear again.
