Apple AirPods Pro and AirPods Pro 2 will receive a free upgrade this autumn.
The latest beta build includes a "customisable adaptive audio mode" for manual adjustment of noise cancellation.
The mode allows users to adjust the level of cancellation and transparency themselves.
Options to "remove more noise" and "remove less noise" have been spotted....
.....and could appear in a full firmware release later this year.
The new mode is part of Apple's full public release, expected to be accessible through the AirPods Pro menu in settings.
Other new features include voice isolation and new gesture controls.
