I'm no audiophile but these sound wayyy better than the previous earbuds that came with the iPods and iPhones. The bass is so nice that you can hear it. You couldn't hear much bass from the old earbuds. I have a pair or ultimate ears superfi 5 pros that sound amazing as well, and would say that these new earbuds are on a scale of 7 out of 10 with the ultimate ears being a 10. Also digging the new design, very clean and minimalistic! Less is definitely more! Way to go Apple.
