How to use

Remove the worn eartip from the headset by gently pulling it off the earbud stem. Align a replacement medium eartip over the stem and push until it seats securely. Verify that the eartip is fully attached and that the headset audio port is unobstructed. For the best acoustic seal, position the headset in the ear and adjust the eartip orientation until comfort and sound isolation are achieved. Replace eartips regularly or when signs of wear, deformation, or reduced audio quality appear.

Recommendations

Keep a supply of replacement eartips on hand in multi‑user or high‑usage settings to maintain hygiene and consistent audio performance. Clean the headset and eartip mounting area periodically with a dry, lint‑free cloth and avoid contact with oils or solvents that could degrade the silicone. Choose the medium size if previous eartips provided a balanced seal; evaluate small or large sizes if you experience fitting issues.
