I always test mixes on other systems: car, crappy PC speakers, boombox etc. I never mix with headphones, but always test the mix with them. You need to test for stereo separation, and test in mono, too.

A mixing tip is to test your mix at barely audible levels, to see if you hear all the instruments. If you do, it should be fine when turned up.

Since murf100, the OP, has been making mixes with too much bass, chances are that he/she has too little bass in the mixing room. You could try different placements of the monitors in relation to the room, especially corners, or perhaps add a subwoofer.
