  3. Adjust the fit of the headset units to your ears.

    Twist the headset unit to slide the earbud tip deep into your ear canal.


  • When you put the headset unit into your ear or adjust the positioning of the headset unit, see the illustration in step 3 for how to hold the headset unit.

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 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.


  • 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.
  • By using “INZONE Hub” or the “Sony | Headphones Connect” app, you can change settings such as the setting for the headset to turn off automatically.

When attaching and removing the headset

In the factory settings, the built-in IR sensors detect if the headset units are inserted or removed from your ears to 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 notification or voice guidance corresponding to the operation and status.

When the headset is removed

  • When the headset units are not worn for about 15 minutes after being removed from the charging case, the headset turns off automatically to save battery. Turn the headset on by tapping the touch sensor or by putting the headset units into your ears.
  • As a means of preventing the headset from reacting incorrectly, it is not possible to play back music, make or receive calls, or perform other operations by tapping the touch sensors of the headset units when they are removed from your ears.


  • You can also play music, make and receive calls, etc. when only one headset unit is worn in your ear.
