Big bro, I’m still learning myself, but one thing I’m starting to understand is that knowing your headphones is probably more important than just having expensive headphones. I would listen to a LOT of professionally mixed and mastered reference tracks that you already know sound good. Learn how the low end, vocals, high end, width and overall balance sound through your headphones. That gives you something to compare your own mixes against. I’d also constantly check the mix on other systems you have access to; car, speakers, earbuds, phone, etc. If you notice the same problem every time you leave your headphones, go back and figure out what your headphones may be hiding or exaggerating. And I wouldn’t try to compensate just because the headphones sound weak somewhere. For example, if they don’t reproduce sub-bass very well, boosting the hell out of the low end until you can hear it could actually make the mix way too bass-heavy everywhere else. 😂 Eventually I’d definitely invest in a good pair of monitoring headphones when you can, but until then, references, learning your headphones, ear training and checking translation can take you a long way. Keep working with what you have, big bro. 🎧🔥
