Cool, but not AMAZING.
I compared them to my skull candy buds, and the bass is pretty much the same. Less vibratey than the skull candy, and you know that annoying sound skull candy's cords make when your walking around and they carry the sound of the cords to your ears? These headphones make the same noise, but not as bad as skull candy. I think these headphones are pretty cool though. I loveeee the colors and they do have a noise canceling effect when you put them in.
