Product Highlights
  • FOR Auracast And Classic Bluetooth Users – Two modes: Auracast for Auracast headphones, speakers, and only the hearing aids shown in the images. Classic Bluetooth for headphones or speakers (only one device at a time). For hearing aids, we recommend Audikast 4 HA.
  • Watch TV At Your Own Volume – Connect to your TV via optical or AUX output for private listening through headphones or hearing devices. Some TVs without optical or AUX output are not supported.
  • Stable And Future-Ready Connection – Built on Bluetooth 5.4 with Auracast support and USB-C firmware updates, designed to stay compatible as Auracast devices continue to evolve.
  • NOT FOR Non-Auracast Hearing Aids – Auracast works only with Auracast-enabled hearing aids. Please check the compatible hearing aid models shown in the images before purchase.
  • IMPORTANT NOTE – Classic Bluetooth Limitation – In classic Bluetooth mode, only one headphone or speaker can be connected at a time. Multi-listener audio sharing is available only in Auracast mode.
