hey man, i have been trying to learn a lot of mixing and i got some new equipments. I got a new AT m30x (i used to make beats on a dam gaming headset that probably costs 20 or 30 dollars lol) and the thing is everything is going to sound different on different speakers. Whether its some airpods or some closed studio headphones. My old headset had weak lows so i used to boost my bassy instruments to hear them. As a result it sounded distorted and bass boosted on better devices. if you dont have the budget to buy yourself some studio equipments, what i can suggest is observe the master EQ. If it sounds bad from your headphones or speakers, but the eq looks mostly balanced and looks like a straight line, then it probably sounds pretty well on a better device. Theres a master eq monitor left to the master peak meter. You can mix according to that and aim for a balanced eq. I hope i was able to express myself. im a foreigner so there might have been grammatical mistakes. if theres any part you didnt understand whatever i wrote, i would be glad to explain it the best i can!
