These have seen everyday use for about a week now and I haven't had a problem with them at all. They come with 3 sets of rubber black inserts. The size I have shown is the smallest of that variety. They also come with 1 set of triangular rubber inserts which look a lot like those shooting earplugs you see at sporting good stores. I really like the earphones. I can't say that the sound quality is absolutely prefect, but it's a solidly built and fairly ergonomic seat of earbuds. If spending the $$$ isnt holding you back, I would recommend these. Edit: also, Hitman. You gotta tell me the details of that hat I constantly see in your pics.
