a mistake made on many of the micro's is its poor headphone jack quality. i'd recommend contacting creative customer support, and they'll send you a new one.
Hello all , I have recently purchased a zen micro 2 months ago or so. Never dropped it or anything but I just noticed a problem that's annoying the hell out of me. Something is up with the headset port. When I shake it in my hand for example it cuts out , music comes out of one headphone ear etc. Also when I turn the headset knob thingy it does the same thing. I've tested it with 3 diff. pairs of headphones so i'm sure it's not the headphones thats messed up. Do I need to upgrade firmware ? Clean the headphone hole or something ? Keep in mind i haven't really used it much, never dropped etc.
