Amps i’m using the beyer dt990s. they’re open back and comfortable, so as long as i’m careful with the levels, i can put 4-5 hours in with no fatigue issues. one wall of my studio is glass and there’s a window too, so there’s absolutely no point in getting proper monitors. i have a good hifi set up with a sub and i use that to check the mix.
it’s just a matter of learning how things sound. i know that if i can hear the bass, but it doesn’t stand out, i’m close. when i check it with the sub, i know if i’ve over-baked it or not. that and reference tracks if i’m not sure and a 2nd set of ears when i send it for mastering really help. the feedback from wayne who does all my masters has been invaluable, it’s helped me learn so much quicker and to train my ears properly.
