content: Since I workout and do cardio six days/week, I rely on my music to keep me motivated. These headphone have very little bass which, for me, make for a weak sound. With other headphones (like the ones that came with my iPod) I normally have the volume at about 75%. In order to achieve the same volume with the Senheiser's I had to crank it up to 95-100%. While they did stay in my ears, I was constantly messing with the green cord (trying to straighten it out) which was very long and never lost it's springy, curled-up shape.
