CLEANING AND REPLACING EARTIPS
IMPORTANT
Over time eartips may lose their elasticity. For best performance and
retention, replace 3-flange eartips every 60-90 days. Replace foam
and glider eartips frequently.
To clean 3-flange eartips:
1. Remove the eartip from the earphone.
2. Clean with water and mild soap.
3. Dry the eartip before placing it back on the earphone.
• Do not expose the earphones to extreme temperatures.
• Avoid dropping and strong impact.
• Leave eartips on the earphones for shock protection.
• Do not pull on the cord to remove the earphone from the audio
device or the ear.
• Clean or replace eartips prior to use by others.
• For best performance and retention in the ear, replace 3-flange eartips
every 60-90 days.
• Replace foam eartips frequently.
