Still struggle in distinguishing between 3K and 4K but for 300 and 400 I kinda view it this way: How far is it from middle A (441)? Also, I kinda remember how 300 Hz sounds just from playing a lot haha

You can train with pink noise in the gym. That helped me in getting a better understanding what I have to focus on and how certain frequencies sound. After a lot of repetition you will get more and more precise. But like almost everything in mixing there is no easy or short way, unfortunately. Cheers!

thank you

It work!
