i personally have gone round this issue a zillion times without finding a good solution whereby mixes done translate well to any listening environment...but maybe i'm just a dummie...lol.
so i resign myself to the fact i just can only do the best i can...
and if i fail...so be it.
This is basically where I have landed, at least at the moment. Since I have neither the funds nor the physical space to get the perfect solutions, I've decided to do the best I can with the imperfect situation, and remember that this is a hobby that's supposed to make me happy, not miserable and frustrated. I just posted my latest song, which was of course mixed with headphones only
(User Showcase thread) . I'm sure all the mixing problems are clear (and perhaps horrifying) to the real audiophiles around here. But I remember what it sounded like at the beginning of the process, so I'm thrilled with the final result.
