Just bought a pair of TH-X00's, and I love them, but the sibilance is a bit much at loud volumes. 
 
Any way to EQ this down? I don't know a whole lot about EQ'ing.

Perhaps. Sibilance occurs in frequencies from 4 to 10 KHz. Different people can be more or less sensitive to particular frequencies. Ideally you would want a parametric EQ, but a graphic EQ could work if you can't get parametric with your software or player. Try cutting around 8KHz, then experiment with the frequency and amplitude to find what works for you.
 
An alternative option to an EQ is a de-esser plugin. A de-esser is a dynamic compressor which acts on the sibilant frequencies, limiting the sibilant energy. Unlike an EQ, it leaves the sound signature of your headphone intact when there is no sibilance. You may need VST plugin support to use it though.

I literally know nothing about EQ'ing, so I don't know what to use and I don't know how to "cut 8KHz."
 
And I tried looking up de-essing plugins, but it's for stuff like Audacity, right? How is that going to help if I'm listening to music through Google Play or something?
 
Sorry for my naiveness, lol.

The first thing to do would be to just get an EQ working, and experiment with it to see how it works. Are you using a Windows PC? On Windows you can use EqualizerAPO to apply EQ to all of you audio. It's not the most intuitive thing so if there is an EQ built into Google Play or another software that you use, you could try that first.
 
Yes, de-essers normally come as VST plugins meant for audio workstations. You can get VST plugins working on some players like foobar, or by routing your audio through a VST wrapper, but that gets complicated and you probably don't want to do that. Just stick with an EQ for now.

A simple trick that can work for some people/headphone combos - a sheet or two of toilet paper or a coffee filter in the ear-cups:

Easy mod and it does take the edge off the super bright bits, 1 or 2 cut squares of TP works wonders.
