Equalizers

Well, you can open up iTunes and look at the equalizer presets; those all are available on the iPod, and if one of 'em suits you, it's an easy solution. The 'custom' setting (one slider per octave) is available for adjustment on your computer, but maybe you can download a custom setting to the iPod, too (mine is an old IOS version, don't know what the new ones support).

iTunes is downloadable for Mac, PC, but not supported on Linux.

I tried the iTunes presets and they don't really fit my hearing loss. At least they don't seem to make the music sound any better. Eric

They won't. You like what you are used to. That is how we work.

You need an accurate readout of what you are hearing now before any meaningful adjustments can be made.

Maybe increase the higher frequency volumes on the equalizer first?

There's a neat little chart on hearing loss as a function of age and frequency here:
