This video shows you the molding stage of making your own ZenPlugs Molded Stethoscope Earpieces. Because they are individually molded to your ears they are far more comfortable than standard eartips. They won't split and fall off and they are even antibacterial, reducing the risk of stethoscope-associated otitis externa. Buy yours today from http://www.zenplugs.com/stethoscope-earpieces-littmann.
