Help with EQ'ing harsh/treble-y vocals

I’ve been messing with EQ for hours in Ableton, Garageband, and Audacity. I’m hoping someone can help guide me with smoothing out some harsh / treble-heavy vocals that hurt to listen to right now. Basically I’m looking for a rule of thumb as to which of the high Hz I should cut out, and how far I should cut them, when using the Graphic EQ tool, to get vocals that sound more like something off your everyday pop song.

Much appreciative. T

The trouble with that sample is that is has already been heavily processed. Almost all the low frequencies have been removed, the very high frequencies have been boosted, and a delay has been added.
In a case like this the Plot Spectrum tool is your friend. For comparison, the spectrum of a normal voice and the spectrum of your sample.

You can see that everything below 400 Hz has been heavily cut, and there is a boost above 4000 Hz. So cutting the high frequencies alone won’t help.

Try this as a starting point. You’ll never make it sound like a voice in an everyday pop song, but after this EQ it is somewhat less grating.
