Summary: Great sound for the price, I prefer them to my Grado SR80. Somehow iGrado sounds a little louder and brighter then SR80 (after i made some penny size holes into cussions even bass is heavier). Still SR80 seems to have more depth and the sound is more relaxed and more enjoyable. Now the bad: they may look like portable but they are open back and leak sound heavily. Also very unconfortable for my ears.
