For the proper sound quality, noise canceling function, and call sound quality to be effective
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.
Referring to step 2, 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.
When attaching and removing the headset
In the factory settings, the built-in IR sensors detect when the headset is attached to or removed from your ears,
enabling the headset to pause or resume music playback, as well as control the touch sensors and voice guidance.
When the headset is worn
You can use the touch sensors to play music, make and receive calls, etc.
You will hear a voice guidance corresponding to the operation and status.
When the headset is removed
When you listen to music while wearing both headset units in your ears, the headset will pause music playback if one
or both headset units are removed. When the headset is worn again, the headset resumes music playback.
When the headset is not worn on your ears for about 15 minutes after being removed from the charging case, the
headset turns off automatically to save the battery. Turn the headset on by tapping the touch sensor or by putting on
the headset into your ears.
In order to prevent the headset from reacting incorrectly, music playback, making and receiving calls, and other
operations cannot be performed when not wearing the headset in your ears, even if you tap the touch sensor.
Hint
You can also play music, make and receive calls, etc. when only one unit of the headset is worn on your ear.
By using the “Sony | Headphones Connect” app, you can change the setting of automatically pausing and resuming the music
playback, or automatically turning off the headset.
