Wireless Noise Canceling Stereo Headset
WF-1000XM4
There is a difference in volume between the left and right units, insufficient low-
frequency sound.
If the size of the earbud tips does not match the size of your ear canals or the headset is not properly worn on your
ears, tap operations or the speech detection of Speak-to-Chat may not be successful, 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.
