Hello,
Yes, the GQ43QN90DATXZG has multiple audio output. To do this, you need to connect your Bluetooth headphones to the TV.
Then activate the "Multiple audio output" function in the menu: 123 button > Settings > All settings > General & privacy > Accessibility.
In this function, the volume of the headphones must be adjusted on the headphones themselves. The remote control then only regulates the sound of the TV speakers.
Best regards from Eschborn

Hello,

You would like to know the difference between the national and international editions.
The country of use and the language are preset accordingly. There are no differences in the functions.

Kind regards
Your FRITZ! team

The TV can output the sound via the TV speakers and Bluetooth headphones simultaneously. The volume of the Bluetooth headphones and the TV speakers can be adjusted independently of each other. The volume of the headphones is controlled via the headphones themselves, while the volume of the TV speakers is adjusted via the remote control. This function is activated via the "Multiple audio output" setting, which you can find under Settings > General > Accessibility.
