Etymotic Research er-22 Guida Utente

White eartip insertion
• For best results, moisten the eartip before insertion.
• Insert the eartip by pulling the ear outward and 

upward. The eartip should seal deeply and 
comfortably in the ear canal.

• Adjust the gooseneck so that the microphone 

is within 1/2" of your mouth.

• Once properly inserted the microphone (boom) 

should not move.

Foam eartip insertion
• Use a foam eartip if a good seal cannot be obtained with a 

white eartip.

• Compress the foam at the end of the earphone by rolling 

it between your thumb and forefinger before inserting it.
Hold the earphone in place for about 5 seconds while the 
foam expands to create a tight seal.

Remove the eartip slowly with a twisting motion to break the seal.
