You might be able to hear certain phenomena better through headphones, but you don't know if you're hearing those phenomena better because the headphones are peaking or dipping in certain areas that are unpredictable, so it could be highlighting certain elements in a false way that flat perfect speakers in a perfect room wouldn't reveal in the same way. I'm not a music maker, but I'd imagine you'd want to tailor mixes to the best most reliable reference standard, which I think would be the best speakers you can get a hold of (within your budget & anechoic EQ'd) and in a room that you've treated (within means) and you've measured at your listening position, equilateral triangle, etc. After talking with an amateur music maker, he used headphones to check the bass detail, but used monitors to balance & create everything else......to me that makes sense.
