5 Stars for noise isolation. 5 Stars for fitment. 5 for style. 5 for overall sound. I don't like a lot of bass anyway. I'd rather be able to pick out the instruments and not have them drowned out by the low notes. Some music I listen to has booming bass passages (think Tommy by The Who) and I need them to boom. They don't. I'd rather cut the bass with my ipod EQ than not have enough. With that said, I'd give them 5 stars for my tastes because they are just about perfect. I only gave them 4 Stars so others will know.
