The REAL BLUE and REAL BLUE NC have an (undocumented) function - a key lock, i.e. the touchpad is locked after activation.
To activate, please press the on/off button together with the Bluetooth button briefly - in the case of the REAL BLUE NC, an announcement "Secure-Mode enabled" follows, in the case of the REAL BLUE, there is an acoustic confirmation by sound.
To deactivate, please press the on/off button together with the Bluetooth button again briefly, an announcement "Secure-Mode disabled" will be made or, in the case of REAL BLUE, an acoustic confirmation by sound.
During the key lock, the power button and the Bluetooth button are also disabled.
How can I tell which version of the REAL BLUE/BLUE NC I have?
The older models REAL BLUE (2020) as well as REAL BLUE NC (2020) have a red fabric cover inside the earphones. The new REAL BLUE/BLUC NC models (on sale from Nov. 2021), on the other hand, are equipped exclusively with a black fabric cover.
The red fabric inside the earphones = REAL BLUE (2020) and REAL BLUE NC (2020).
