I have used these earphones for a little under 2 years. I have small ear canals so getting a good seal has been tricky. However, with some practice I managed to get a pretty good sound. These are great sounding phones for the audio savy. I can really hear my music come to life on my Ipod and Zune HD. Most people think I am crazy for paying a lot for earphones but I am an audiophile at heart.
