Selecting an Eartip
The eartip that is most comfortable is the likely choice, but it must
seal well for maximum protection. Important: Sound quality, full
bass response and noise isolation all depend on a good eartip seal
in the ear canal.
All Etymotic eartips are designed to be safely inserted into normal,
healthy ear canals. Do not insert anything into your ear canal if you
have discomfort or foreign material in your ears.
