these headphone sound pretty good , but it be difficult to analyze they very extensively before you head start throb from the impressive , but painful amount of pressure . I think maybe I just have a massive , sensitive head until I notice this be mention in many other review . the advice to stretch they out on a couch arm or basketball be good if you be already stick with they and have to make it work , but I would think the average consumer would want to avoid this if there be lower maintenance headphone option .
