The LG OLED55G59LS is not directly compatible with Oticon Intent hearing aids via Bluetooth, as is the case with normal Bluetooth headphones. Oticon hearing aids use a special 2.4 GHz radio protocol and not classic Bluetooth audio. To transmit the TV sound directly to the hearing aids, the Oticon TV Adapter 3.0 is required. This is connected to the TV (e.g. via the optical audio output) and streams the sound wirelessly to the hearing aids. The Bluetooth function of the LG TV alone is not sufficient for this.
