the sound quality on these headphone be pretty much what you would expect from Sony for this price , i.e. , not spectacular but good treble , slightly less good bass . to be honest , if you be jogging , you would hardly notice unless you be use to awesome sound all the time . my only problem with these be the problem with all stiff-headband headphone ; if you have a small electronic device -lrb- md or mp3 player -rrb- the headphone can not be cram wherever you put the device -lrb- unless you be willing to break you new headphone , which I negligently have do -rrb- . so , good for the sound , not as portable as the playing device of the 21st century .
