They fit everyone but me, again. Let me tell what my problems with it are, someone out there will likely have a similar problem. They look small in the picture, and, in fact they are small. The part you don't see, with the tip, is small indeed. So small, I find it difficult to get a seal in the ear canal, and the round outer chamber doesn't allow you to push it in any more. Wide tips help some, Complys help some, still not completely comfortable for me (I'm in a minority here for sure, but, could be someone else who feels the same). They are nice when a good seal is acheived (lots of comments on that in the thread). I may have to go back to Ety's...along with the Tenores, the easiest fit for me. (found them unreliable, though, just died on me...also hate the filters).
