The Shorty model will give you all of the bass you need without distorting your music. Hear the difference when you put these headsets on as you will go beyond sound and actually feel your music. Order one for everyone you know! Our Shorty MP3 model is designed for users who are looking for some "pumped-up bass!". Shorty is a hybrid of our SB-X and Mavericks models...a small, light-weight sport model with a fabric, tangle-free cord.*** PLEASE NOTE - the cord length is only nineteen inches (21") which is substantially shorter than our regular cord length. This length is specific to this model ONLY and is perfect for those who run or exercise with an iPod or other music player that is attached to a hat, neck strap, or around the head to reduce cord slack.
