I bought these after I went through a set of comply foam tips. I hoped they would be as good or better but I was not impressed at all. They are so slick and do not compress well. I still haven't used the last set. Switched to westone instead.
Poor quality. Just putting these tips on an iem left a crumbly residue on my fingers. Not sure how long these will last. Will update score if these last longer than expected.
