Many users have requested an Auracast™ microphone solution. We’ve released an iOS and Android app that lets you broadcast your voice by simply plugging in the FlooGoo FMA120 and tapping a single button.
My Samsung Galaxy S25 fe does that without the need of any other device.
Thank you for sharing— the S25 may have some important differences from the S23 Ultra we tested.
Here are the software versions on our S23 Ultra; they’re current as of today.
It offers an Auracast transmit option, but it appears to work only with the built-in media player; there’s no way to broadcast the microphone.
Samsung also displays the current track title in the broadcast information—visible to all nearby receivers, even when encrypted—which isn’t ideal for privacy.
Compared with a microphone broadcast from an iPhone via the FMA120, the key difference we observed was reliability: with our test hearing aids (ReSound Nexia 9), the Samsung broadcast wasn’t received consistently, whereas the FMA120 was stable. Auracast and LE Audio typically take more time to integrate into a complex mobile platform that must manage coexistence with other radios like Wi-Fi; a dedicated USB dongle such as the FMA120 avoids that complexity and can be more stable.

I really have no need for aurcast, but having LE audio makes my life very comfortable and I have now the S25fe. The sound is great. The only reason I upgraded was I needed the larger screen due to my vision. I don’t listen to music often but I find that streaming from my phone using Amazon prime music is good enough.

That’s completely understandable. LE Audio comfort plus the S25 FE’s larger screen sounds like the right fit for your needs.
For context, we built the mic app after a forum user asked for a standalone Auracast microphone. A true standalone would require new hardware—costly to build and less convenient than a phone with a small FMA120 adapter. With the app, we can add features like voice levelling and fine-tune the mic experience more easily and powerfully.
Thanks for sharing your experience—it helps others decide what they actually need.

How would I use this - can you give me some scenarios that this is used in- some examples?
Also is this iPhone compatible or only Android?
Thank you.
Suppose you’re hosting a house auction and expect some audience members to be wearing hearing aids. Since you can’t rely on having an installed Auracast™ transmitter on site, you can simply use the dongle with your phone. This way, anyone with Auracast-enabled hearing aids—or with a FMA120 set to receiver mode—can easily tune in to your channel and hear you clearly.
The iOS app is already available—see the first post for details—and the Android version will be released soon.

ah! so the dongle becomes the Auracast xmtr to them ?
My problem is that people are complaining about how I sound -muffled, distant, unclear on the phone using Phonak Spheres and iPhone 12Pro . With my HAs, is Android the long term solution? Can anything be done with iPhone? Any work around or accessory? I need to replace a phone in the family and could give them mine if the 17Pro is of any benefit?
How is your 121 coming along - when available?
At the request of a Phonak user, we developed a special firmware that routes calls through the phone’s microphone instead of the hearing aids, which helps improve call quality. For real-world performance, you may reach out to Jack, as we don’t have a sample unit to test ourselves.
The 121 is expected to launch in Australia within the next month, and it should become available on Amazon US about two weeks later.

awesome Ranson! Would this custom firmware work with the 121 ?
Is the 120 ergonomically better fitted to this use?
Is there a lightning adapter to your FMA120 that you recommend.
Any members here using this approach… PLEASE message me or post link to your experience with it. TY!
We’ll also update the special firmware so it works with the FMA121.
The FMA121 requires a small USB-C cable (included in the box) to connect with USB-C phones. For iPhones with a Lightning port, however, the FMA120 may be the better choice, as Lightning-to-USB-C camera adapters are still uncommon and the available Lightning camera adapters tend to be bulky with multiple ports.
In our testing, we used the fourth option shown in the image below, though any of these should work with the FMA120. Just be sure the seller offers returns in case of a faulty unit.
The special firmware lets you use your phone’s microphone for calls, so as long as you speak into the phone as usual, the remote audio quality is guaranteed. The only trade-off is an additional ~0.1 second delay in the audio you hear from the other side, which may make replies feel slightly slower in conversation.
