Avantree Audikast 4 — Bluetooth 5.4 TV Transmitter with Auracast Support, Works with Headphones & Auracast Hearing Aids

Built to support Auracast-enabled hearing aids such as GN Danalogic Extend, Jabra Enhance Pro 20, and ReSound Nexia, the Avantree Audikast 4 enables direct broadcast to modern assistive devices. Note: pairing requires a compatible source device (for example, Galaxy S20+) or the official hearing aid apps for initial setup. Turn your TV into a private listening system by connecting the Audikast 4 to TV audio (Optical/AUX) and streaming to Bluetooth headphones from brands like AirPods or Bose. It also lets multiple people listen simultaneously, making it ideal for family TV time, group listening sessions, or small venue audio sharing. Connectivity and range: in standard Bluetooth mode the transmitter achieves up to 165ft (50m) line-of-sight. When using Auracast mode, range can extend up to 330ft (100m) in open-air conditions, depending on the receiving device and the environment. Future-ready firmware updates are delivered over USB-C (DFU) so the unit can stay compatible with evolving Bluetooth and Auracast standards. A clear front display shows pairing and status information at a glance, and the tactile volume knob provides direct, easy control of output levels.
