Auracast for public areas, offices or homes
Broadcast audio in various settings such as churches, concerts, museums, airports, buses, stores, TVs at the gym or home, or even transform your old Bluetooth phone into a broadcaster.
Note for TV users: Many TVs have USB ports that only support external storage, not USB audio output. Please confirm whether your TV supports USB audio output. If not, check if it can pair directly with a Bluetooth headset — in that case, you can set the FMA120 to relay mode to enjoy Auracast (see our support page for setup instructions). Alternatively, you may choose the FMA121, which features a 3.5 mm analog input for easier TV connection.
*For hearing aids that don’t natively support Auracast: You can load the Auracast receiver mode firmware onto a second FMA120 and use it with your mobile phone to enable Auracast reception.
Online chat or meetings
Your headset or earbuds' operations are transferred to standard USB HID input for your host, ensuring compatibility with VoIP Apps including Microsoft Teams.
Note for hearing aid users: For the best compatibility, please update the dongle's firmware to the latest version as indicated in the FlooCast app. Confirmed compatible models include GN ReSound Nexia/Vivia/Savi, Jabra Enhance Pro 20/30, Oticon Intent, Philips HearLink 9050, Rexton Reach, Signia 5IX/7IX, Starkey Edge/Omega AI, and TruHearing 7.
*Phonak and Kirkland models that use classic Bluetooth can also be supported through classic Bluetooth with the mSBC/WBS codec.
Four-step quick start. Full user guide details are on the back of the package.
Device Firmware Upgrade
Keep your device running at its best by updating to the latest firmware.
Option "Prefer using LE audio"
Enable "Prefer using LE audio for dual-mode devices" before pairing your LE Audio earbuds, headphones, or hearing aids. The FlooGoo FMA120 supports LE Audio hearing aids with the LC3 codec. Please do not confuse this with legacy MFi or ASHA models. Confirmed LE Audio-compatible hearing aids include:
- Jabra Enhance Pro 20/30
- Oticon Intent
- Philips Hearlink 9050
- ReSound Enzo IA, Nexia, Vivia, Savi
- Rexton Reach
- Signia 5/7IX
- Starkey Edge/Omega AI (note: the Starkey Genesis line does not support LE Audio)
- TruHearing 7 Advanced / TH 7 Premium
Additional new models may also be compatible even if not listed here.
Disable Competing Bluetooth Connections
When pairing LE Audio devices like hearing aids, make sure other Bluetooth connections are disabled — for instance, switch off Bluetooth on your phone or TV streamer.
- When your hearing aids are powered on, they automatically reconnect to their paired phone. This can prevent another device (such as the dongle) from pairing and connecting. To ensure successful pairing, please first turn off or disconnect your hearing aids from the phone.
Put Devices into Pairing Mode
Hearing aids typically enter pairing mode when placed in their charger and then removed after a few seconds.
- For Oticon Intent and Philips HearLink 9050, please ensure they are within 20 cm of the FMA120 during pairing.
- Note: Most LE Audio hearing aids currently do not support multiple simultaneous connections. This means you cannot connect both your PC (via this dongle) and your mobile phone at the same time. However, this is a limitation of the hearing aids, not the dongle. In fact, when paired with Starkey Edge AI, the FMA120 dongle supports smooth switching of audio and calls between PC and mobile. For the best experience, please encourage your hearing aid vendor to improve and update their technology, rather than assuming the dongle is limited.
Desktop App "FlooCast" to configure mode and show which Codec is in use - Bitrate and RSSI for Adaptive/Lossless Audio, aptX Lite in Gaming
You can also use it with both iPhone and Android devices with a USB-A to USB-C adapter.
Our FlooGoo FMA120 offers versatile working modes to cater to various Bluetooth audio needs. Whether you require high-quality lossless Bluetooth audio for your aptX adaptive-enabled headset/earbuds, the latest LE audio connection utilizing the LC3 codec, low-latency audio and voice connections for gaming, or transforming your Raspberry Pi into an Auracast broadcaster, achieving these functionalities is just a few simple clicks away.
* When a new firmware version is available, the FlooCast app will provide a download link. Please download and unzip the firmware into a folder with a full path containing only English characters to ensure a smooth upgrade process.
* For pairing and use with aptX Lossless-enabled headsets or earbuds: Please disable the "Prefer using LE audio for dual-mode devices" setting.
* For gamers: Start by pairing your headphones or earbuds in “High Quality” mode, then switch to “Gaming” mode for lower latency. The FMA120 supports not only devices with Qualcomm chipsets, but also many popular models — including Samsung Buds 2, Buds 3, Buds 3 Pro; Sony LinkBuds S, Inzone Buds, WF-1000XM5, WH-1000XM6; Technics EAH-AZ100; and Xiaomi Redmi Buds 6 Pro.
*For hearing aids: Ensure the FMA120 firmware is the latest version 1.1.2+ and enable 'Prefer using LE audio for dual-mode devices' for optimal hearing aid compatibility. Set the FMA120 to 'High Quality' mode and pair it with your hearing aids for seamless music streaming and smooth online chatting or meeting experiences. The FMA120 is compatible with a variety of hearing aids, including GN ReSound Enzo IA/Nexia/Vivia/Savi (firmware9.68.1+), Jabra Enhance Pro 20 (9.68.1+), Oticon Intent (1.1.0+), Philips HearLink 9050 (1.1.0+), Rexton Reach (25.5.972.3+), Signia 5IX (25.5.972.3+), Signia 7IX (25.5.1039.3+), Starkey Edge AI (10.0.0+), TruHearing 7 Advanced (25.5.972.3+) and TruHearing TH 7 Premium (25.5.1039.3+) delivering crystal-clear audio for calls, meetings, or gaming. Some older hearing aids, like the Kirkland Signature KS10, can also be supported via classic Bluetooth using the "mSBC/WBS" codec. Most hearing aids do not support multiple connections. To pair the hearing aids with the FMA120, simply turn off Bluetooth on the paired phone and any connected TV adapter, if applicable. Alternatively, if using a USB-A to USB-C adapter with the FMA120 for calls and music on your phone, consider removing the pairing from the phone. This ensures seamless switching between PC and phone—just plug the FMA120 into the desired source for effortless connectivity.
*For Oticon Intent and Philips HearLink 9050: Please ensure the hearing aids are updated to firmware version 1.1.0 or later. If needed, contact your audiologist for assistance. Place the hearing aids within 20 cm of the FMA120 during pairing. This requirement is based on Philips' online help documentation and is not a limitation of the FMA120.
* When using Auracast with hearing aids, please disable the 'Broadcast High-Quality Music' option, as most hearing aids do not support 48kHz sample rate music streaming.
* For hearing aids that don’t natively support Auracast: You can load the Auracast receiver mode firmware onto a second FMA120 and use it with your mobile phone to enable Auracast reception. Please refer to our online manual for detailed instructions.
* Note for TV users: Many TVs have USB ports that only support reading external storage, not USB audio output. Please check whether your TV supports USB audio output. If it doesn’t, see if your TV can pair directly with a Bluetooth headset — in that case, you can set the FMA120 in relay mode to enjoy Auracast. Alternatively, you may want to wait a few months for our upcoming model, which will feature a 3.5?mm analog input for easier connection to TVs.
* The FMA120 is an officially Bluetooth SIG-qualified Auracast product. It has been confirmed to work with the following devices (not an exhaustive list): Creative Aurvana Ace 2, Jabra Enhance Pro 20, ReSound Nexia hearing aids, Samsung Buds 2 Pro, Sennheiser MOMENTUM True Wireless 4, Sony Linkbuds S, and Starkey hearing aids.
*For Auracast setup with hearing aids on an Android 14 device, such as the Samsung Galaxy S23, you may need to toggle Bluetooth, Airplane mode, and the LE Audio switch multiple times due to a known bug (expected to be resolved in Android 15).
*The FMA120 can set up Auracast directly with paired LE audio devices, eliminating the need for a phone.
* Refer to the online manual via the link on the package for detailed guidelines or contact support through the email provided.
