I almost always use my phones with wired headsets. This lets me get things done while I'm on the phone, and avoids having a crick in my neck after hours on the phone.
Problem is, they've never worked well. People are always asking me to speak up so they can hear me, even when I have the volume cranked. The latest one has dropped below usability. I don't have to yell, but I do have to use what I'd call a loud singing voice. OTOH, if I pull the headset and just use the phone, I can speak normally and they have no problem hearing me.
I can't believe that everyone who uses these things has this problem? Am I missing something about them? Is there some spec that has to match between phone and headset? Does anybody make an amplifier for them?
