Selecting an eartip:
No two ears are exactly alike. The eartip that is most
comfortable is the best choice, but it must seal well
to prevent feedback (whistling) and provide proper
protection.
When changing eartips make sure the eartip
fits securely on the stem of the device.
Greatest sound reduction is achieved
with deeply-sealed foam eartips
