the sonys pack a little more punch and have a little deeper amount of bass. but the downside is that they are kinda bulky.
if your skiin wit just a beanie, go wit the sonys
if you skiin wit a beanie and a helmet, go wit the icons or the smokin buds.
the icons and the smokin buds are the ONLY sklullcandy headphones i would reccomend.
whenever im riding with a helmet i just put my smokin buds or my full metal jackets in. if i dont have my helmet on, ive got my icons over the strap. sometimes, but not very often i ride with my loriders, but those have to be under the strap, and then it looks goofy imho. so i save the loriders for just wearing around, and school and stuff.
hope that helped a lil bit.
