They're not perfect but they do the job considering Oakley OEM parts are hard to come by these days. no problems, but the earplugs were another issue. They're a little less flexible and harder to put on, probably because they're a bit thicker than the original earbuds. Be prepared to put a lot of effort into getting them to the end of the temple, but once you do they feel pretty solid and will likely last longer than the original ones. These earbuds also feel a little "stickier" (by which I mean less slippery), which is a good thing.
