These headphones have amazing sound quality. It's very comfortable, and the choice of three sizes for the buds let me use a size that actually fits in my ear. My problem with them though is that the wire is of a strange material that has an odd flexibility and the parts around the volume control (which is amazing by the way) breaks easily. Also, when the wire hits things, or when I move around too much and it rubs against my clothes, the sound travels and I can hear it in the headphones which can get annoying. It's not enough to make me change them for something else though.
