To check it out, head on over to the Settings app, and then touch “Music.” Under that heading is “EQ,” so pick that.
Within there, you’ll see all sorts of audio adjustments you could try, including settings like “Treble Booster,” “Small Speakers,” or “Rock.” Most of these only apply to music you’re listening to, but the one we’re going to turn on—“Late Night”—works on video output, too.
Once you touch “Late Night” and see the small checkmark appear next to it, you’re done! You can go and pull that episode of “Rick & Morty” back up to see if you can hear and understand it more easily. Just remember to turn the EQ setting to another option when you’re wanting to listen to music. I mean, I’m sure someone could tolerate Pink Floyd all compressed and stuff, but heck, that sounds like blasphemy to me.
