Depending on what you're sensitive to, you might try to use an EQ to adjust the treble down a bit. Not sure if the HyperX comes with software that includes an EQ, many headsets do though and while it isn't necessary can come with extra features (many of which can be total garbage to the final audio output).
I prefer to use
EqualizerAPO +
PeaceUI and a 32-band EQ that I tune, works pretty damn well. You can just edit the EQ text file for EQAPO and not use a GUI, or use a different GUI solution for the EQ. There are other options, this one I have used for years because it just works, is very easy to manage/maintain and is lightweight.
Also if you go the EQAPO route, select the correct audio output devices, you don't have to reboot.
Rather, start up CMD as administrator and run the commands:
net stop audiosrv
net start audiosrv
That'll restart the audio service, which should let EQAPO to modify the sound ouptut of your audio devices. By taking the time to tune the EQ, you can make some noticable changes to the overall sound. I usually use it to emphasize bass for music and movies, and emphasize mid/lower treble for games (if I'm playing anything competitively which is rare anymore). But even with an EQ you won't make a bad pair of headphones or headset sound good, but you might make it more tolerable.
