These are pretty good earbuds, especially for the sound. They have a couple of issues however in my day to day use. I prefer to use my beats headphones for noise cancelling and sheer comfort while working. They are wired. At a push I can use the skullcandy and they start to feel a little uncomfortable at the hour mark. So thats the first thing. For the gym and running that’s probably not going to affect you.
Skullcandy XTFree Bluetooth Wireless In Ear Sport Earbuds with Mic are a solid buy. The dropouts are not enough to worry about and they really do hold in the ear excellently not falling out the sound is great and they look good too.
