right, this is my first pair of IEMs.
i can also hear these hissing noises when i plug x3i into my laptop. i checked, they're called sibilance. i didn't notice beforehand (had been burning in right now totaling < 50 hrs). otherwise they're working quite well/ improving i must say.

i don't have a portable rig (i don't listen to music on the go + can't afford 'em, what's the point?) so i can't test these on other devices to tell if there's any difference. is this normal occurrence for IEMs? is there a way to reduce the level of sibilance when i listen to the songs? it does get *very* annoying for certain songs i listen to.

also about the tips, are the tips walabies/ yuheng selling to fit the mylars of superior quality than the ones which came w/ the package?

nah, i ripped them in flac format, and most tracks i downloaded are at least 192kbps.
i bumped the volume up to the max w/o any music playing and there's definitely hissing noises on the background. i wonder if it could be my laptop.
when i listen to ambient stuff the noises really get in the way

thanks for that. there's nothing i can tweak i suppose...
i guess i'll have to live w/ it for the time being, argh...
