I have own three pair of these earbud for my iPhone . the first last for almost a year until the left earbud -lrb- microphone side -rrb- no longer produce sound . think that a year be a decent amount of time for such inexpensive earbud with a mic , I order another pair as replacement . that pair last 4 week before the mic stop work and produce bad static when use the phone -lrb- they still work with the ipod function for some reason -rrb- . Amazon be kind enough to send I a new pair ... unforunately those last only 2 day before the same thing happen . I 'll go with a different brand this time .
