My parrot chewed thru my standard iPOD headphones so I thought I would purchase this "in-ear" phones as replacement. When I plugged them in I could not believe how poor they sounded. There is no bass, very limited dynamic range (like an AM radio) and they don't fit well (even with different size ear plugs). WARNING!!! DON'T BUY THESES. If you need to replace your ear phones just get the regular ones that come with the iPOD. Also, I contacted apple about this and I can only say that they were very uncooperative. I love Apple (I own a G5 dual 2mhz) but Apple bombed on this one - big time. A message to apple - this is not a product up to your high standards. Don't rune the iPOD's great reputation by risking the possibility of someone hearing an iPOD with these headphones and comming to the wrong conclusion about the iPOD's quality. You need to pull this product or improve it ASAP.
