I use these headphones for running, specifically at the gym, and after years of frustrating runs where I'm fixing the buds every few minutes I have found a pair that DOES NOT MOVE!
Pros:
- Fins prevent movement of ear buds while running and fit wonderfully right out of the box. I didn't find them awkward or uncomfortable.
- Drowns out all outside noises - great for the gym
- Above average sound quality, wish there was a bit more bass (ipod adjustments made no difference)
- Volume control buttons on wire allows for easy access while running
Cons:
- Not suitable for outdoor running, at least on busy streets, because you won't be able to hear what's going on around you
- Wish the bass was better
Overall, the headphones are great and the best I've ever had. I'd definitely recommend them to all runners. The only reason I subtracted a star was because of the bass. Long runs need killer bass.

This is the only headset that I have found where the ear pieces stay in your ear, thanks to the unique components that lets you configure a size that fits your ears uniquely. You can combine the ear plug sizes with different sizes of the ear flang to find a unique fit. The audio quality of the microphone is excellent according to my friends too. This is the best sports headset I have found for the iPhone.
