Get different headphones? Headphones present an unrealistic sound to your ears from their proximity. If you mix with headphones, you have to learn how to adjust so that the mix sounds good elsewhere. No matter your monitor situation, you need to learn how to make it sound good on any system. Mix, burn a CD< then listen to it on every different system you can - home stereo, friend;s stereo, car system. Make notes on what needs to be adjusted, remix, do it again. Eventually you will intuit what the sound needs to be like in your headphones to sound good elsewhere. There are endless debates in other sections of this forum on the headphone vs monitor thing.
