these headphone have good noise cancelation and sound , but the thin padding on the actual earphone make my ear hurt after a hour or so . I do not have any problem with the folding design and weight of the headphone , like many other reviewer appear to have . if you want good noise cancelation for a affordable price , get these ! to make they more comfortable , simply cut out two earphone-shaped piece of foam or other soft material , take off the muff , put the foam in they , and put the muff back on . after this modification , the headphone do not hurt my ear .
