Comments about Skullcandy Asym iPhone Headphones:
These really good for use with a helmet. I often ride my bike to work and for a long time had pain-in the-butt ear buds that would keep falling out. An over-the-head set would not work because of my helmet. As these wrap around my ears they stay on well while riding. These headphones do however block out most ambient noise so I'll most likely get hit by a car. I think it's probably worth it.
