Howdo I distinguish between left and right?

The right earplug is red, and the left earplug is blue. You can differentiate them
by the color of the initials on the product. Please note this when collecting ear impressions. (However, for aviation, we make them in left ear and right ear models.)

There is no distinction between left and right eartips
