Common Questions

Oasis Aura FAQ

Which devices can receive Oasis Aura?

Compatible Auracast-enabled hearing aids, headphones, earbuds, receivers, and speakers can join the broadcast. Support and joining steps depend on the receiving device.

Does it work with regular Bluetooth headphones?

Not directly. Oasis Aura broadcasts Auracast audio. Regular Bluetooth headphones require a compatible Auracast receiver adapter, such as Aura C.

Which audio sources can I connect?

Oasis Aura accepts Optical, 3.5mm AUX, and Bluetooth audio from TVs, media players, phones, computers, mixers, and PA systems. Because mixer and PA outputs vary, use our Cable Finder to identify the correct connection for your equipment.

Find the right cable for Oasis Aura →

What is the operating range?

The rated receiver range is up to 100m / 328ft line of sight. Walls, interference, and venue layout can reduce usable coverage.

Can visitors join by scanning a QR code?

Yes. A QR code can be generated for the Auracast broadcast. Visitors with compatible phones or hearing-aid apps can scan it to join. Venues can print and display the QR code at entrances or listening areas. Device and app support may vary.

See compatible devices and QR Code details →

Can I create separate listening groups with multiple transmitters?

Yes. Each group needs its own transmitter and compatible receiving devices: AuraClip, Auralink, Harmony A1/A2 speakers, AuraCoil, AuraBand, or Eon Aura headphones—with more to come. Connect each group’s devices to its transmitter to listen to different audio simultaneously.
