Wireless Noise Canceling Stereo Headset
WF-1000XM4
Replacing the earbud tips
M-sized earbud tips come attached to the left and right units of the headset 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,
tap operations or Speak-to-Chat speech detection may not work correctly, or you may not obtain proper sound qualities,
noise canceling effects, or call performances.
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 size of the left and right earbud tips may be different. The
“Sony | Headphones Connect” app will help you to determine which earbud tips are most suitable for you to achieve
the optimal noise cancellation effect.
Check if the headset is properly worn on your ears. Wear the headset so that the earbud tip is comfortably situated
as deep in the ear canal as possible.
