these sound pretty good for $ 15 dollar headphone but beware of one thing ... the power output of you device and here 's why . to make decent sound headphone at a lower cost , they must sacrifice the magnet quality . when you have a less efficient magnet , it require more power from the device to move the magnet , and thus the speaker driver . these sound ok with my creative zen and I could not seem to get the sound loud enough to drown out outside noise . then I try my studio , higher quality headphone with be 3x the size with a 50mm driver and it be significantly louder with the same device , which it could only do because of the magnet quality . I try they with a ipod , and because they have a high power output , I could get the volume I need from these , but it may be different for any non ipod device . so if you be use these with a ipod , do not fret and go for it , they sound great , especially at this price . however , beware that they may not potentially meet you need if it be not a ipod or smaller device .
