Summary $20>Better than stock apple headphones. Way better. To me it's worth the cheap price. They fit fine in my ears, they also go in fairly far. Sound blocking works but only gets noticeable when you have the music turn up a little. **Cheap upgrade from apple headphones, worth the $20 to me) I previously had skull candy $50 ear buds, these compare moderately.**
Pros Cheap, comfortable, decent sound if you aren't terribly picky
Cons Not the best sound quality in the world.
Summary I have very small ears so it's difficult to find earbuds that fit comfortably and don't fall out, or feel crammed in. I've tried sever brands including models with removable pads. These feel amazing. The sound quality is good enough for listening to your ipod. I was surprised at the noise isolating that they provided. I can listen to music much lower and hear great. At $10 I would buy these over and over. Great set of earbuds for a casual listener.
Pros Cord doesn't tangle too much
Cons Tinny sound, screeching sss, no sliding loop (for easier storage).
Summary Spend the extra couple of bucks for Skull Candy.
