Do the REAL BLUE (2020) / BLUE NC (2020) headphones have aptX?

The REAL BLUE and REAL BLUE NC have an (undocumented) function - a key lock, i.e. the touchpad is locked after activation.

To deactivate, briefly press the on/off button together with the Bluetooth button again, an announcement "Secure mode disabled" or, in the case of the REAL BLUE, an acoustic confirmation tone. The on/off button and the Bluetooth button are also deactivated during the key lock.
REAL BLUE/BLUE NC (2020): The touchpad no longer responds
