These are hands down the greatest ear buds you'll ever buy. Those one's you get with the Ipods are crap compared to these.
You know when your in a crowded place listening to music and all the noise filters through your regular earbuds (not those giant headphones but ear buds)? Yeah it sucks, but you'll never experience that again as these cancel all noise. Their amazing, all you hear is your music, and in the best possible sound quality too.
My one Complaint is that they take a little while to get used to, look at the picture, you need to stick it all the way in your ear and that can be uncomfortable. But you'll get used to it as it comes with 3 different size endpieces.
