These headphones are AMAZING. If you're like me, regular earbuds refuse to stay in your head. Any time you move, they fall out. Not a problem with these. The cord is designed to loop over the back of your ears, so the earbuds themselves nest perfectly inside the ear. They weren't going ANYWHERE.
They're a bit pricey, retailing for $39.95 (I got mine on eBay for about $10 less, and amazon is selling them even cheaper), but I found them to be well worth the expense.
