Ok, so I am a Nano fan. The headphones supplied with iPods are all kinds of horrible though. I did however take the plunge and spent the $30 on sony's in ear headphones. Which turned out to be a horrible mistake made twice. Excellent sound quality horrible engineering in terms of product tolerance. Just from being in my pocket, both pairs of the sony MDR-EX71SL/WK white wire covering striped off and then the left earphone stopped playing sound. So after having this happen twice I dove in deeper to regain the quality of sound that the Nano harnesses: I went mac yet again, with their in ear headphones, and I am loving it. The engineering behind the tolerance on these is still to be determined, but I do love the way the headphones fit the ear better.
