If you are on an airplane, we recommend that you turn on the NC Optimizer function at the stable flight condition.
The condition optimized with the NC Optimizer function is retained until the NC Optimizer function is used again. It is
recommended that you turn on the NC Optimizer function once again after getting off the airplane and so on.
The NC Optimizer can also be operated from the “Sony | Headphones Connect” app.
Note
Put on the headset under the actual usage conditions when running the NC Optimizer. It is recommended that you do not touch
the headset while the NC Optimizer is running.
If the headset receives another operation while performing the NC Optimizer, the optimizing is canceled.
If the CUSTOM button is set as the Google Assistant button, the NC Optimizer function cannot be operated from the headset.
If the CUSTOM button is set as the Amazon Alexa button, the NC Optimizer function cannot be operated from the headset.
