Excellent sound, very clear, and not aggressive. I use them with Cowon J3, and I'm so glad I bought two. These are the best headphones that I could find, taking into account comfort. These headphones are very comfortable, not like most of the ITE, where we feel like corks stuck in the ear canals. They are open headphones, so that do not compensate a noisy environment; against by this feature gives the air to the sound; we did not like listening in a sealed jar. They come with a fairly large rectangular bag, which allows not to nitpick to wrap them before storing it.
