Input:
This is the second pair of Koss ear phones that I have bought.  They do not bother my ears as many other ear phones do, especially the Apple earphones.  These are like memory foam and they form to your ears.  They are very comfortable.  I wear them at least 6 hours a day while working.  There are times that I have them in my ears and have no music going.  I use them to drowned out office noise.  I believe the sound quality is good as well.
