Avantree Audikast 4
TV transmitter with optical and 3.5 mm inputs that broadcasts over Auracast to any number of receivers, or switches to classic Bluetooth for a single pair of headphones.
Auracast status
Confirmed by the manufacturer, the Bluetooth SIG product listing, or an independent test. Sends either an Auracast broadcast or a classic Bluetooth stream to one listener, not both at once.
The consumer sibling of the Audikast 4HA, and the transmitter Avantree bundles in its AuraCoil TV set.
