ELI5, what's the difference between using headphones for producing (versus listening)?
When you're listening to music for pleasure, you generally don't care about how the song will sound when you're listening to it on speakers or on your apple earbuds. You also usually want the bass and treble to be extra-pronounced and clean, because they're the most "interesting" sound ranges.
When you're listening to music because you're producing or mastering, you want all the frequencies to be as equal as possible. The bass should be at the exact same actual volume as the highs, and the entire frequency range (even slightly below human hearing) should be audible, in case there's a really low bass sound that's messing up your mix. If the bass is really loud or really quiet on your headphones, they will sound the opposite on a balanced pair of speakers or headphones, or even louder on something even more pronounced.
p sure that's right
