The headset does not operate properly.

You cannot operate the headset if it is not worn. Put the headset into your ears to operate.
To operate the headset, tap the touch sensor correctly. Hold the headset between your thumb and middle finger, then
tap the touch sensor with your forefinger.
The headset cannot be operated when the touch sensor or your fingers are wet. Wipe off any perspiration or water
with a soft dry cloth before operation.
The headset cannot be operated with gloved fingers. Operate the headset with bare hands.
The headset cannot be operated when the touch sensor is covered by your hair. Clear the touch sensor so that you
can tap the touch sensor directly.
Be precise in tapping the very center of the touch sensor. If the rim of the touch sensor is touched, the headset may
not operate.
Tap the touch sensor with the ball of your finger. If you tap with your nail or fingertip, the headset may not operate.
Tap the touch sensor while holding the headset between your thumb and middle finger. If the headset moves when
you tap the touch sensor, the headset may not operate.
When you change the assignment of the functions to the touch sensors with the "Sony | Headphones Connect" app,
confirm on the app that the correct function is assigned to the touch sensor.
Reset the headset. This operation does not delete pairing information.
If the headset does not operate properly even if you reset the headset, initialize the headset.
