Best-in-Class
A no compromise, high-performance noise-isolating headset + earphones that delivers best-in-class benefits and superior value, perfectly matched to the latest product innovations from Apple®.
Selecting an Eartip
The eartip that is most comfortable is the likely choice, but it MUST SEAL well in your ear. If you can easily hear others when the volume is off, you don’t have a good seal. Twist it in deeper, or choose another eartip.
When changing eartips make sure the eartip fits securely on the stem of the earphone.
Proper Insertion

tab Important: Sound quality, full bass response and noise isolation all depend on a good eartip seal in the ear canal. View Earphone Insertion Video
- Carefully insert the earphone while pulling up and out on the back of the ear.
- Twist the earphone up into the ear canal while inserting, until outside noise is blocked out.
- 3-flange eartip: Moistening eases insertion.
- Foam eartip: Roll down or compress foam eartip before inserting. Hold the eartip in place for about 5 seconds while the foam expands to create a tight seal in the ear canal.
- Glider eartip: Simply push into ear canal.
Removal
Remove earphones slowly with a twisting motion to gradually break the seal. Do not pull on the cable to remove the earphones.

- Clean or replace eartips prior to use by others.
Cleaning and Replacing Eartips
Over time eartips may lose their elasticity. For best performance and retention, replace 3-flange eartips every 3-6 months. Replace foam and glider eartips regularly.
To clean the 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.
About the Filters
hf3 headset + earphones have special filters that smooth the frequency response and prevent earwax from entering the earphones. A filter is located at the end of the earphone and is visible when the eartip is removed. If a filter becomes clogged, it should be replaced. A dirty filter will reduce earphone output. A filter should be changed if the loudness decreases or the sound quality declines.
