The size refers to the length of the headband extension to the cups. If you can find a picture of an SA5K it uses the same system, but its not permanent; it slides. On the Qualia, this can be adjusted with great care and a jewelers screwdriver (phillips), but its really not that important. Mine are set at 7, and my heads probably a 4. Hope this helps.
