I ordered two of the satin soft earpieces - one for each ear - from Avery Sound less than one year ago. They are great! The quality is outstanding, the fit is perfect, and the noise reduction-like capability makes it easier to hear radio/landline calls. I highly recommend ditching the usual pink earpiece that comes standard with your headset for a custom model.
Is the isolation good/bad? I've used custom molded earbuds for live sound/music, where they are designed to block out outside sounds, but I'm not sure this is good/bad in ATC? Does anyone suggest the ones like the cops have where it allowed ambient noise in addition to the radio? Just curious on everyone's opinion.
You only wear it in one ear, so you still hear everything normally around you, it just makes the sound coming through the headset much clearer. I had one for years and it broke and i can't stand using the little pink buds now. A good mold will never pop out, and it's so comfortable you forget it's in sometimes. I have to crank the vol up with the bud, with a mold i routinely kept volume turned nearly as low as it would go and heard fine.
I've had a few different molded earpieces and this is the best one I've had. It was easy to do the molding, and I did it by myself even though it says to have someone help. The turnaround was fast, and the earpiece itself is nice. It has the feel of a thick gummy bear.
