Hopefully, this is helpful: Yes, the LG B4 OLED TV does support Auracast. LG has confirmed that Auracast is available in their 2025 OLED TVs, including the B4 series. This feature allows for one-to-many audio broadcasting, enabling multiple users to connect headphones or hearing aids simultaneously for shared listening.

If your hearing aid has volume controls, to adjust the volume with the volume button on your Bluetooth device, set Settings > All Settings > General > Accessibility > Listen Together with Hearing Aid to Bluetooth Device. For Bluetooth devices that do not have volume buttons, you can adjust the volume of the device in the detailed settings screen of Bluetooth Device + TV Speaker. If Settings > All Settings > General > Accessibility > Listen Together with Hearing Aid is set to Bluetooth Device, only one Bluetooth device can be connected, and depending on the type of your Bluetooth device, you may not be able to connect two devices. You can adjust the volume of the internal speakers and hearing aid separately when you connect the transmitter of the hearing aid to the HDMI (eARC/ARC) port. Go to Settings > All Settings > General > Accessibility > Listen Together with Hearing Aid and choose HDMI(ARC) Device. The TV's optical digital output and HDMI eARC will be deactivated when streaming audio to Bluetooth headphones or speaker...^Ivan.
