Selling a pair of Sony MDR-XB300's. This was the smallest size in Sony's now discontinued and missed "Extra Bass" family of headphones. 30mm bass driver, hence the 300 name. Produces amazingly clear, deep, tight bass for something so small. Plush real leather covered cups, although they are not really cups as they sit on your ear, rather than around your ear. I have had these for several years and have kept them in immaculate condition. No original packaging included, just the headphones. Asking $40.
