I bought the OK3 a while back, and I've been enjoying them for the most part but I can't seem to get a good fit. The rubber(?) covers are the worse...the only way I can make them fit is by using the soft covers. But after a little use these seem to lose their ability to fit as well.
I recently bought the JVC Gummys as a cheap pair to leave at work, and they are a lot more comfortable. I think the OK3 might be a little big, but I'm not entirely sure since I don't have a lot of experience with earbuds.
Anyone else have any similar issues?
