Eartip Maintenance
Visually inspect your eartips before each use for signs of
discoloration (soiling) and note any changes in flexibility. Eartips
that display any of these signs or other significant wear should be
replaced. 3-flange eartips should be replaced every 3 to 6 months
with average use. For heavy use (8-16 hours/daily) they may need
replacement in 3-6 weeks.
Foam eartips typically need to be changed more frequently than
3-flange eartips. Individual experience will vary, depending on total
use time and environmental conditions.
• Examine eartips after each use.
• Do not immerse earphones in water.
• Do not clean with harsh chemicals. Alcohol is not recommended.
• 3-flange eartips can be removed and cleaned in mild detergent
before reattaching. Dry eartips thoroughly.
• Do not expose to extreme heat or moisture.
• Avoid dropping or hitting on a hard surface.
• Use only accessories from Etymotic Research, Inc. to ensure
continued performance to specification.

Insertion
Make sure the eartip is clean.
• When using foam eartips:
Roll down or compress foam
before inserting (Fig. 1).
• Pull the ear up and out while
inserting (Fig. 2).
• Twist and push gently until the
eartip seals in the ear canal.
• Hold the eartip in place for about 5
seconds while foam expands to create a
tight seal in the ear canal.
• When using 3-flange eartips:
Moistening may ease insertion.
Removal
• Remove earphones with a slow twisting motion.
Do not pull on the cables to remove the earphones from the ears.
Storage
• Always store earphones in a clean, protective case.
• Do not store other objects in the earphone case.
