So, a friend of mine apparently has very tiny ears, and the smallest tips that come with KZ Ate (about 4 mm) won't fit. Are there any replacement options with smaller tips, (under 10$ preferably) that would work with these IEMs? Thanks..

Hey. I've always been wary of In-Ear phones as I could never find them comfortable. I've found both earbuds and IEMs to be very uncomfortable. They either always come off, or they hurt the ears. Currently I have Brainwavz HM5 (thanks to this forum!) and I'm loving those. But I now need something...
