Replacing the earbud tips

M-sized earbud tips come attached to the left and right headset units at the time of purchase.

If the size of the earbud tips does not match the size of your ear canals or the headset is not worn properly in your ears, you may not obtain the correct sound qualities or call performance.

If any of this is the case, try the following.

  • When changing the earbud tips, try the earbud tip sizes in order from the larger ones to the smaller ones. The most suitable size of the earbud tips for left and right ears may be different.
  • Check that you are wearing the headset properly in your ears. Wear the headset so that the earbud tip is comfortably situated as deep in the ear canal as possible.

The size of the earbud tips can be determined based on the number of dotted lines inside the bottom of the earbud tips.

LL size: 5 lines

  1. Remove the earbud tip.

    Hold the headset unit and twist the earbud tip while rotating it to pull it out.

    Do not pinch the end of the earbud tip when removing it.

  2. Attach the earbud tip.

    Push the earbud tip firmly onto the sound conduit (sound output tube) on the headset so that the earbud tip covers the inner end of the sound conduit. Do not attach the earbud tip in a loose or skewed manner.

    If the earbud tip is not completely attached, the earbud tip may be removed from the headset, reducing the sound quality and wearability.
