Summary: I use the earbuds on my dog walks and they are very comfortable and stay in your ears now matter how fast you want to run. It drowns out enough of the ambient noise to enjoy the music you're listening to. Although it isn't completely tangle proof, it is much much better than the stock apple earbuds.
Summary: These are great headphones for a runner or probably any athlete. I use them for long distance running. They look a little bulky but their comfort is amazing. They never fall out and they do not hurt your ear or cause any ear fatigue which is rare in my opinion. Sound quality is decent. They are a little pricer than I normally pay for headphones but they were definitely worth the money.
Summary: Great for running. They really never fall out. Sound quality is good without totally isolating you from ambient/environmental sounds (safety issue when running). Pause/play/skip function works but not the volume control.
Pros: stay in ears when running
Cons: volume control does not work with my Samsung Galaxy 3
