Query: Volume problem

I should have believed the other reviewers who reported problems with volume. This headset just isn't loud enough (and I have normal hearing). With the phone volume set to maximum, and the headset volume control set to maximum, it was just barely loud enough--actually, slightly less than loud enough. I liked other aspects of the item, but a telephone headset you can't hear is useless. Maybe it will work with other phones (mine is a Panasonic cordless), but it certainly didn't work for me.
