You generally don't want something bass heavy for monitoring. DT770s are technically "studio" headphones, but a lot of pros aren't going to use them because they have a lot of bass but are lacking in the mids. KRKs aren't going to have thumping bass, but they are going to be the best for actual monitoring. Comfort may be a bit of an issue. I feel like they are akin to the Sony MDR series. Not very comfortable, but they are not meant to be. They are workhorses.
One question I do have that could affect these recommendations is why are you driving the headphones from your laptop? I understand that you are making electronic music, but are you just doing that in garage band or a similar program? Or do you have a separate keyboard/synth setup? Do you have actual studio equipment?
If you are just making music for yourself and your friends to listen to, then you honestly probably don't want a monitoring headphone, because they aren't much fun to listen to. If you are producing music to sell or something, thats one thing, but if not I think you might find that a traditional bass-heavy, non-studio can may be a lot better for you. You can still make the music you want, but when you play it back it will be a lot more enjoyable. Just a thought! If you want other suggestions, let us know!
When you're talking about comfort are you talking about the Shures or KRKs? I understand that studio monitors are more-or-less used only as a reference, and you're supposed to do monitoring on actual monitor speakers. But since I don't have any (yet) I need headphones that I'll be able to use the whole day.
And now to the question: I don't have any studio equipment, so I had to start somewhere and figured that first I'll need to buy gear that effects to sound first (cans, speakers, audio interfaces) and those fun things after (MIDI controllers, keyboards, launchpads). Right now I am just making music for myself and friends, but I think it's kinda training for me, I still don't know that much about sound design, I make dubstep so I need to learn about FM synthesis to make growls and other crazy ****. I go to guitar lessons and a part of that are music theory lessons once a week so that helps me with writing melodies and chord progressions (but I'm still awful at the chords). I want to produce and sell music for sure when I get older (I'm 14). And BTW, how old do you have to be to sell music? I live in Slovakia (Europe) if that helps.
Real thanks for the help so far guys!
