Basically what everyone else is saying. These headphones are great. They fit perfectly in my Giro Nine.10 helmet. The sound is great, they fit very well.
Just like everyone else says, the Mic1 is a huge pain in the ass. I think its about time Skullcandy come out with Mic3. I bought a pair of Skullcandy in ear Mic3 and they work great at my desk. When will the Cassette's get the same feature? Idk, but I am sure I will buy when they do!
