aptX Low Latency supported transmitter - no lip sync delay , Optical Input, LED indicators.

  • WIRELESS AUDIO STREAMING: Use the Audikast to Bluetooth-enable your TV, AV Receiver, PC/Laptop or other audio source to wirelessly stream music to your favorite Bluetooth headphones. (NO built-in BATTERY - power using a TV/PC USB port or a USB charger with 5V/0.5-2A output via included cable.)
  • WORLD’S FIRST DUAL-LINK aptX LOW LATENCY Bluetooth Transmitter: The Audikast uses aptX Low Latency to reduce audio lag to undetectable levels (<40ms) making it ideal for watching TV/movies. Dual link feature also enables simultaneous streaming to 2 HEADPHONES NOTE: 1) For best results ensure your headphones also support aptX-LL. 2) Conditions in which Dual Link may not work as well - 2 speakers, 1 headphone + 1 speaker, 2 true wireless earbuds, 2 different brands/models of headphones.
  • 100FT / 30M LONG RANGE: Using Class 1 Bluetooth technology and an optimized antenna, the Audikast can reach up to 100ft! NOTE: Operation range is affected by physical obstructions (walls, people), wireless interference (Wi-Fi routers, Wireless TV adapters) and also depends on receiving device (e.g. TWS earbuds and devices with small internal antennae may have shorter range).
  • OPTICAL / AUX / 3.5mm / RCA AUDIO OUTPUT SUPPORTED: Wide support for multiple audio output standards - optical audio, Aux or RCA, and even computer digital USB audio without the need for additional cables. (NOTE: Audikast does NOT decode Dolby/DTS - only PCM)
  • USER-FRIENDLY INTERFACE: Clearly visible status indicators allow you to see when device is in pairing mode, when it’s connected and what type of codec is in use. Independent buttons for handling 2 device connections allows for easy and intuitive control.
