Summary

The maker's setup and troubleshooting guide for AuraCoil, a personal Auracast receiver with a built-in neckloop for hearing aids and implants with a telecoil.

Key findings

  • Describes AuraCoil as a receiver with a built-in neckloop that passes public Auracast broadcasts to hearing aids or a compatible cochlear implant in T or MT mode, with no separate receiver or cable; the listener must wear the complete neckloop around the neck.
  • Says the receiver joins a nearby public broadcast automatically, that holding the channel button for 5 seconds switches to another broadcast, and that "Encrypted broadcasts are not supported yet": a future phone app, not yet available, is to let it join them over Bluetooth Low Energy.
  • Gives volume and left/right balance controls, advises starting at a low volume and keeping the whole neckloop around the neck when sound is quiet, uneven or cutting out, and tells listeners who hear nothing to ask venue staff whether the broadcast is active and public.
  • Gives up to 20 hours of listening per charge, using a charging dock; a replacement battery is sold separately.

Limits

A maker's guide for its own product, with no measurements: neither the guide nor the product page (https://avantree.com/products/auracoil-auracast-personal-receiver) gives a field strength, frequency response or latency for the neckloop. The product page, published on 14 May 2026, offered the receiver for pre-order on 10 October 2026 and names Auri, Bettear, Williams AV and Avantree transmitters as compatible in its image captions. The date is the guide footer's printed last-update date, 13 October 2026, also reflected in its HTML version label.
