Is the quality of headphones important?

My friend and I have been using the Advanced focus 10 track, he is using 150$ Bose headphones,and I'm just using the ones that came along with my mp3 player. Should I upgrade, or does it really matter what kind of headphones you use as long as they are stereo?

As long as the headphones are in the 15 - 24.000 Hz frequencyrange and there is no noise canceling technology in them, it all boils down to comfort. Whatever brand, as long as you stay inside these frames should do the trick.
