I can hear it up to 19KHz for sure with the 80s but I do have to turn it up.

The only way you can know whether or not your hearing sucks is by going for a test. So do yourself a favour and go for one so that you're not forever wondering in high anxiety. The 80s and a test CD are not the way to test your hearing.
