Seriously, has everyone forgotten what a "phone" is? I mean I have trouble hearing and don't like to hold long conversations on the phone, but it's still one of the quickest ways to get in touch with someone.
Hadn't heard of that one and had to look it up... but no, my problem is that I had a loud car stereo when I was younger and blew out my hearing in the upper ranges. I can hear better in my right ear, but usually put the phone up to my left. When it's quiet I can understand people just fine, but when there's background noise it makes them a lot harder to understand. If I'm watching videos at my computer I can turn down the bass and turn up the treble, then I understand the dialog just fine, but everyone else in the house complains that it's now too loud.
I've had over 30 years to adjust and I make do, but don't try to talk to me at a concert. :-)
