Etymotic The BEAN® Quiet Sound Amplifier® - Manual (Page 9)

INSERTION & REMOVAL
Insertion
• Make sure the eartip is clean.
• Pull the ear up and out while inserting.
• Twist and push gently until the eartip seals
in the ear canal.
• When using 3-flange eartips, moistening may
ease insertion.
• When using foam eartips: Roll down or compress
the foam eartip before inserting. Hold the eartip
in place for about 5 seconds while foam expands
to create a tight seal in the ear canal.
• When using glider eartips no compression is needed;
simply push into your ear.
Removal
• Remove QSAs with a slow twisting motion.
• After removal, place your device(s)
in a protective case.
