Input: Great quality and performance. They sound great and I find that I don't need to turn the volume up very loud because of how well the isolation works. I even put them through the washer and dryer and they came out fine. My only issue is that after using them for about 20 minutes they start to hurt my ears and i have to remove them for a few. I'm not sure why this is but I guess it has something to do with how long the foam tips are... any solutions?
