These Teflon earscopes are designed to direct ozone into the ears.
This earscope has two advantages: it's made of ozone-resistant Teflon and comes with removable ear buds. This makes it easy to share the earscope with others and/or replace theear buds. It comes with two. Additional pairs can be added on with the earscope for less (see Available Options above) or purchased later. Ear buds twist on easily and securely.
