https://wccftech.com/apple-releases-airpods-pro-firmware-2d15/ > AirPods Pro owners should receive a brand new 2D15 firmware update right about now. Hopefully, the new update fixes the active noise cancelling bug. > Apple released the 2C54 firmware update a while back and needless to say that it wasn't one which users were hoping for. It broke noise cancelling to some extent in favor of more bass and frequency response. Hopefully, the new firmware update, dubbed 2D15, fixes all that.
