Thanks for your reply! I am about to call you guys to get this sorted out. The molds by themselves seal quite well (although I can work them out of my ears by wiggling them. However, when I add the earpieces, there is a definite issue with the right one. The hole is at such a poor angle on that one, that the earpiece can't sit flush in my ears, it pulls the mold out of my ear (breaking the seal) and sounds like it may even be blocking the end of the nozzle. Oh, and if the seal on the foam tips is a "10" I would say these are an "8".
Also, why was I told on the phone that there is only one material for these when in fact there are two (and I didn't get what I was told I would)?
Hopefully we can get this straightened out on the phone. Thanks for your assistance.
