broadcast audio is becoming more widely supported across major hearing-aid brands, and until Nov 2025, our testing has confirmed reliable Auracast reception with models from Jabra, GN ReSound, Beltone, Philips, Oticon, Starkey, Cochlear, and more.

Auracast vs LE Audio (Unicast)

  • Auracast = one-way broadcast audio (no microphone return).

  • / Unicast = two-way audio capability (mic + voice), but implementation varies by brand, and compatibility is not yet consistent across the industry.

Many hearing-aid users are finding that Auracast works similarly across brands, while LE Audio / Unicast behavior differs greatly—sometimes even between models within the same brand. Your reports will help clarify what currently works, what doesn’t, and what needs improvement.

Why We’re Doing This

Our goal is simple:
to gather real-world feedback so this technology can better serve hearing-aid users as it evolves.

Any honest experience—good or bad—is helpful. We welcome your:

  • Hearing-aid model

  • Which Avantree transmitter you used

  • Auracast vs Unicast results

  • Stability, delay, range

  • Tips, issues, or feature requests

Avantree Auracast Ecosystem25

Our ecosystem now includes a wide range of Auracast transmitters, receivers, loops, earbuds, speakers, and accessories, all designed to work together as the standard matures.

My first C82 LEA worked fine 3 weeks long, then I upgraded FW to 10.7.5 it failed once, then the 2nd was success. I reset the C82 LEA. After that always pairing issues with intent FW 1.2.1. I reverted back to 10.6.9. same issues.

Either the device hardware failed on FW update or something else failed. I also had weird color codes on C82, blue and green which shouldn’t happen.

The problem was constant green light with no sound, or only 1 sided ear sound.

I returned the C82 LEA to amazon and got a replacement. This is on 10.6.8. and it works perfectly for 2 days now. I’m afraid to FW the C82 again, it simply works and did work with the first unit until I FW updated it and reset it, which was recommended.

Hi Gerhard, thanks for the detailed report — very helpful.

We now have FW 10.7.6 available for the version.
It’s true that 10.7.5 still has some issues, and what you experienced aligns with what we’ve been fixing.

To help you properly, could you let us know which hearing aids you’re using?
If you email our support team, we can send you 10.7.6 to try, which should resolve the pairing and color-code problems you saw.

Thank you for your patience, and we appreciate you sharing your experience.

which hearing aids you’re using?

Intent 1, with FW 1.2.1, like I said. I have no issues with the shipped 10.6.8. I’m going to stay on the old one it seems to work very well. It looks like the new ones frimwares try too much to work with all brands and brake something.

Are you sure your firmware updates can not brake the pair key when they fail? should the hearing aids be on during firmware update and reset afterwards?

Does Avantree have a device which will allow me to pipe my MacBook Air M1 audio into my Rexton Reach hearing aids? I bought the Floogoo but the configuration instructions are too complicated for me at age 89 and it seems to require access to a Windows computer which I don’t have.

I have Intent 1s and would like to from my LG TV.

I have a LG soundbar connected using HDMI ARC.

Whilst the TV has an optical audio output, it requires selecting optical ( either alone or plus TV speakers) and disconnects the HDMI ARC output.

Avantree has the HAX06 that connects between the TV HDMI ARC output and Soundbar HDMI input. In bypass mode provides sound (& supports CECC) to the soundbar and to an optical output on the HAX06.

This avoids having to change the TV sound output settings.

The HAX06 is quite expensive and requires an additional Auracast transmitter to achieve what I need.

I would like Avantree to produce a variant of the HAX06 that includes an Auracast transmitter.

Is this being considered?

Edited

I am aware of the FMA120 and discounted it

I need the functionality of the HAX06, ideally with the transmitter built in, not just a standalone Auracast transmitter.

Also, I thought this thread was started by Avantree to gather feedback on the use of their products.

Thank you @PhoebeY for the update.

I think an HAX06 with a built in transmitter will be a fantastic device.

Many thanks for the free offer…much appreciated.

We’re currently looking for users of hearing aids that support but are not yet enabled for to participate in testing our C82 LEA transmitter. The C82 LEA works seamlessly with LE Audio hearing aids to stream audio with low latency and high-quality sound using the codec.

If you have hearing aids such as:

  • Starkey Livio series

  • Phonak Paradise

  • ReSound ONE and LiNX Quattro

  • Signia Pure Charge&Go AX

  • Eargo or similar LE Audio-compatible devices

We’d love for you to try the C82 LEA and share your feedback with us! The C82 LEA will allow you to stream audio directly from devices like a MacBook Air, smartphone, or TV to your hearing aids without needing complicated configurations or a Windows computer.

What we’re looking for:

  • LE Audio-enabled hearing aids (with or without Auracast support)

  • Feedback on ease of use, audio quality, and connectivity

  • Experiences with low latency, sound quality, and device compatibility

If you’re interested in testing, please reply to this post or send me a direct message! We’re excited to hear your thoughts and improve the product based on your feedback.

Thank you for your time and support!

What would be really nice is an alternative to the Phonak wireless microphone system (Roger Select, Roger Table Mic, Roger On) to work with any brand of at an affordable price. Perhaps incorporating to make conversations seamless. Though, this requires latency to be sufficiently low as to be unnoticeable; otherwise, the user speaking will hear their own echo (delayed sound coming back to their hearing aids) which would make the mic system unusable.

The firmware update in July 2025 provided on some of their 2025 TVs

I have a 2023 TV and it doesn’t have Auracast. It has the most up-to-date firmware (Dec 2025) and Auracast is not shown in any of the system settings.

I suspect the necessary Auracast hardware isn’t fitted to pre 2025 TVs…that’s why there’s no Auracast on older TVs.

I have no plans to replace an excellent TV that’s only 2 years old.
