ETYMOTIC RESEARCH BEAN Brushed Gold Quiet Sound Amplifier (ER135-QSA-BG)
After I finally figured out which ear piece fit, the sound amplifier worked great. But after a short period of time it fell out of my ear and I thought that I'd lost it, only to discover that I ran over it with the car in the driveway, after just a couple of days of use!
