have be listen to my ipod with the include headphone for so long , I figure that all in-ear headphone sound pretty crappy and could not pick up bass . when those break I buy these and WOW , there a huge difference ! everything sound much cleaner and it pick up a much higher range of sound that could not even be hear before . also , the shape of they be a much better design than the standard ipod headphone , they be more comfortable and be very secure , they will not fall out when you go run . I wish I would have upgrade a long time ago , . these be a lot better than I expect for the price . Might not be for the hardcore audiophile , but for around $ 20 it be definitely worth it to upgrade you ipod headphone to something that do not sound like garbage .
