I have exams to study for tomorrow -> thus the perfect time to check the web. Electronic Musician's Studio Buyer's Guide deals strictly with studio recording, but they have a couple a lengthy articles on headphones and reference moniters. what I got out of it that should help me mix in my bedroom: higher frequencies sound much brighter through headphones (I kinda knew this already). But they also said this increase in brightness tires the ears faster; again why it is good to break often during final mixing. the article on moniters is cool, discusses the history and the technology, but for those of us who can't afford moniters and use plain stereo speakers: try to equalize your stereo as best as possible so that when given a sound equally covering all frequecies, the speaker outputs all frequencies at the same level. uh i guess you can do this by recording your speaker with a microphone (if you know how to eq your mic settings). otherwise it is just important to know that most home stereos boost hi & low end frequencies, meaning your mids get covered.
