The Timekettle M3 real-time translator headphones are mainly designed for translating languages in real time, listening to music and making phone calls, but they are not specifically designed to connect to TVs or streaming services such as Netflix.

You can connect the headphones to your smartphone via Bluetooth and use translations there, but they do not offer direct support for translating audio content from TVs or streaming services. Such applications would require more specialised solutions or devices designed to translate audio from media sources.
