Got a zen micro silver 5gb, any questions just ask

I bought my 5Gb Black Zen Micro just over a week ago. I was wondering if you've used any other earphones with it? I've found that the ones that came with it, whilst soudning good and giving really, really good volume are bad at cutting off outside sound and awful at fitting in even large ears like mine.

I've tried using my Sony Fonetopia MDR-EX71SL earphones with it but I find that instead of having to listen to a track at 13 I have to listen to it at 18 or 19. Its a shame because the MDR-EX71SL's are really good at keeping outside noise out.

Which earphones are you using and do you find that you have to increase the volume??

i use d creative 1s. i too find they r big and bad at keeping noise out.i tried using my sony mdr-v250 s but the sound sucks
