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 being worn properly in your ears, tap operations may not work correctly, or you may not obtain the correct sound qualities, noise canceling effects, or call performance.

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

  • Change the earbud tips to ones that fit more snugly in your ears. 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.
  • INZONE Hub” or the “Sony | Headphones Connect” app will help you to determine which earbud tips suit you best to achieve the optimal noise canceling effect, sound quality, etc.
  • 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 function that determines the optimal earbud tips for you measures the air-tightness of the earbud tips and determines whether or not the headset units are being worn in your ears correctly. Select a size that fits comfortably.

  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.
