I use my iPod a lot. The earbuds that came with it were comfortable to me. I like the kind that rest just on the outside of the ear canal. No in-ear earbuds for me. I don't know if it is because I use them so much, or because of quality issues, but the earbuds that came with the iPod lost sound on one side rather quickly. I purchased two or three sets that had the same problem, until I discovered the JVC Gumy brand of headphones.
These were less expensive than the others I had purchased, so I half expected them to have short lived usefulness as well. But so far, I have been pleasantly surprised. I liked the first pair I bought so well, I decided to get another pair so that I didn't need to tranfer them back and forth between my Zune and my iPod.
The fun thing about these headphones is that they come in bright colors. So mine are lime green, and peach pink. The wires are a convenient 3.3 feet long.
the next time you need earbuds to listen to your electronic gadgets, take a look at the JVC Gumy brand. I did, and now I am a fan.
