Sony WI-1000XM2 Help Manual page 107

Hint
When you set up the headset to Amazon Alexa, the C (custom) button will be automatically configured for Amazon Alexa. You
can restore the button back to original function by changing it with the "Sony | Headphones Connect" app. Similarly, you can
reconfigure back to Amazon Alexa if you have previously connected to Amazon Alexa, but have changed to other function.
Check or update the software version of the headset with the "Sony | Headphones Connect" app.
When Amazon Alexa is not available for reasons such as not being connected to the network, the voice guidance "Either your
mobile device isn't connected; or you need to open the Alexa App and try again" is heard.
Note
If the C (custom) button is set as the Amazon Alexa button, the noise canceling function, Ambient Sound Mode and NC Optimizer
function cannot be operated from the headset.
If the C (custom) button is set as the Amazon Alexa button, the Google Assistant function cannot be operated from the headset.
Amazon Alexa is not available in all languages and countries/regions. See
