Rexton hearing aids use Bluetooth Low Energy to connect with mobile devices and to support audio streaming.
On Apple® devices, Rexton uses the Made for iPhone (MFi) protocol for direct streaming.
On Android devices, Rexton uses ASHA (Audio Streaming for Hearing Aids) if supported by the phone manufacturer.
Please note that not all Android phones support ASHA. Whether a device works with ASHA depends on if the manufacturer has implemented it.
To see which Android phones are compatible with ASHA and have been tested by Rexton, please visit the Device Compatibility page.
Bluetooth-enabled Rexton Reach hearing aids that have the appropriate firmware are compatible with LE Audio, which uses the LC3 codec for streaming.
LE Audio offers benefits such as improved sound quality and reduced battery consumption.
To find out whether your specific hearing aid model supports LE Audio and the LC3 codec, contact your Hearing Care Professional, or refer to your hearing aids' model firmware version.
You can use the TV Sound, Smart Mic, and Smart Transmitter 2.4 to stream audio to your Rexton hearing aids. These accessories provide a reliable way to stream audio from TVs, mobile devices that don't support the MFi, ASHA, or LE Audio protocols, and other external sources directly into your hearing aids.
Rexton hearing aids may be discoverable by some third-party devices because they use Bluetooth Low Energy for app control, which these devices might detect. However, audio will not stream unless the device supports one of the specific protocols Rexton hearing aids use for audio transmission: MFi (Made for iPhone), ASHA (Audio Streaming for Hearing Aids), or LE Audio (only supported by some hearing aid models).
Bluetooth-enabled Rexton hearing aids with the correct firmware may also pair with select Apple computers that support the MFi protocol. For more information on compatible macOS devices, check Apple’s support documentation.
If a third-party device supports the LE Audio protocol and can pair with Rexton hearing aids that have firmware that supports LE Audio, streaming may work. This depends on both the hearing aid model and the capabilities of the device.
The most effective way to stream audio from your TV to your Rexton hearing aids is by using the TV Sound accessory.
When your Rexton hearing aids are connected via Settings > Accessibility > Hearing Devices on an iPhone, you’ll see a variety of options to customize how they interact with your phone:
- Play Ringtones: Choose whether your iPhone ringtones play through your hearing aids
- Play System Sounds: Control if system sounds (like alerts, key clicks, or lock sounds) stream to your hearing aids when the phone is not in Silent Mode
- Audio Routing: Set whether call and media audio automatically route to your hearing aids or stay on the phone
- Control Nearby Devices: Allows other iOS devices using the same Apple ID to control your hearing aids. For the best experience, we recommend turning this off to avoid interference
- Audio Handoff: Allows one Apple device take over the streaming connection from another automatically. To prevent interruptions, it's best to keep this off
- Hearing Aid Compatibility: Only relevant if you're using the phone traditionally (held to the ear). This setting doesn’t apply if audio is being streamed or on speaker
When you tap on your hearing aids listed under MFI Hearing Devices with a Connected status, additional settings appear:
- Stream to right/left device: Turn audio streaming on or off for either hearing aid
- Adjust Independently: Allows you to control the microphone levels for each hearing aid separately
- Microphone Level Sliders: Adjusts how much environmental sound is amplified (e.g. face-to-face conversations)
- Presets: Displays the hearing programs your Hearing Care Professional has added
- Start Live Listen: Use your iPhone’s microphone as a remote mic. Great for conversations in noisy places. Volume can be adjusted using your phone's side buttons
- Forget This Device: Unpair your hearing aids from the phone
Yes, you can have more than one iOS device paired to your Rexton hearing aids. If the devices share the same Apple ID, the pairing may even sync automatically through iCloud.However, streaming can only happen from one device at a time.
To switch:
- First, turn off Bluetooth on the device currently connected for streaming
- Then, turn on Bluetooth on the second device
- The hearing aids should automatically connect to the new device if previously paired or synced
- Follow the same steps whenever you want to switch between devices (i.e. disconnect from active device and then connect on the second device)
How to pair your hearing aids
First, check that your hearing aids aren’t blocked by earwax or debris. This could stop streamed audio from coming through, even if the hearing aids amplify environmental sound normally.
If needed, follow the unpairing and repairing instructions provided in the appropriate section above.
If you're using Reach R Plus hearing aids and audio is only reaching one ear (e.g. just the right hearing aid), make sure both hearing aids are in wearing position. Correct alignment between the hearing aids is important for stereo streaming. If one hearing aid is tilted or not sitting level, it can prevent audio from being heard in both ears.
- Try force closing the Rexton App:
- On iPhone: Use the app switcher gesture to swipe up and close the app. If you're unsure how, see Apple’s step-by-step guide here: https://support.apple.com/en-us/109359
- On Android: Tap on the 3 lines in the top left of the app and go to Settings > Stop the app > Stop app. Alternatively, you can go to the phone's Settings > Apps > Rexton App > Force stop
- Reopen the app and check whether the Bluetooth connection reestablishes. If not, restart the phone and try again.
If the issue continues, reset the app:
- Open the Rexton App
- Tap the three-line menu icon (top left)
- Go to Settings > App settings > Set up the app
- Tap OK when prompted (this won’t affect your hearing aid settings)
- Choose the Bluetooth setup option and follow the on-screen instructions
If the app still can’t find your hearing aids, unpair and re-pair them in your phone’s Bluetooth menu (see pairing instructions in the appropriate section above), then return to the app to retry the setup.
For Reach R Plus hearing aids, you only have to unpair/forget the items with the "LE_" prefix.
Afterwards, return to the app and retry the setup. The line item for the streaming connection (i.e. the one without the "LE_" prefix) does not need to be unpaired/forgotten.
Still not working? Uninstall and reinstall the app. After reinstalling, reopen it, accept permissions and terms, and go through the Bluetooth setup again.
If you've turned your phone's streaming volume to 100% using the volume buttons on the side of the phone and the audio is still not loud enough, start by making sure your hearing aid domes or tips are clean. Clogged tips (e.g. from earwax) can weaken or even mute both streaming and environmental sound output from the hearing aids.
If everything looks fine and sound is still too low, consult your Hearing Care Professional. They can increase the default streaming gain in the hearing aid settings, so you won’t need to rely solely on your phone's volume. They can also fine-tune frequencies to improve streaming clarity.
iPhone:
For non-Bluetooth Classic hearing aids (i.e. MFi hearing aids):
- Go to Settings > Sounds & Haptics and increase the Ringer and Alerts slider. Also, go to Settings > Accessibility > Hearing Devices > make sure the Play Ringtones option is enabled.
For Bluetooth Classic hearing aids:
- If iPhone is on Silent mode, go to Settings > Sounds & Haptics and increase the Ringer and Alerts slider
- If iPhone is on Ringer mode, the ringtone volume is tied to the in-call volume (how loud you hear the caller). During a streamed call, use the volume buttons on the side of the phone to raise the in-call streaming volume. This will boost the ringtone for future incoming calls.
Android:
For hearing aids using ASHA:
- Go to Settings > Sounds and vibration > Volume
- Make sure both the Media and Ringtone sliders are raised
- If the phone is on Sound mode, the ringtone will stream to the hearing aids and through the phone.
- If on Vibrate, the ringtone won't stream
- If on Mute, ringtone volume is controlled by the Media slider and will only stream through the hearing aids. On some Android phone models, Mute mode will prevent the ringtone from streaming to the hearing aids. If this is the case, switch the phone to Sound mode.
For hearing aids using LE Audio or Bluetooth Classic:
- The ringtone volume is tied to the in-call volume (how loud you hear the caller). During a streamed call, use the volume buttons on the side of the phone to raise the in-call volume. This will boost the streamed ringtone volume for future calls.
- Also make sure the Ringtone slider in the Volume settings isn’t set too low, as this could make the ringtone stream inaudible.
Let’s check the call audio routing settings on your iPhone to ensure calls are directed to your hearing aids:
- Go to Settings > Accessibility > Touch > Call Audio Routing
- Select Bluetooth Headset
Now try receiving a call and see if it automatically plays through your Reach R Plus hearing aids. If the call still isn't going to the hearing aids, on the call screen, see if the Audio button is available. If it is, tap on it to see if the hearing aids are listed as an option. If the Audio button isn't available and/or the hearing aids aren't listed as an option after tapping on Audio, the hearing aids are either disconnected/unpaired, or call streaming is disabled in the hearing aids. If you can stream regular media audio (e.g. music), it's most likely the latter. See your Hearing Care Professional to enable call streaming.
Rexton Reach R Plus hearing aids are Auracast ready. This means that a future firmware update will make them Auracast compatible. Rexton will continue to monitor Auracast development in the industry and public infrastructure to ensure that when we release the firmware update, it will contain the optimal specifications for a smooth experience.
You can change the audio routing using your phone’s native settings:
- iPhone: Open the Control Center (e.g. swipe down from the top right corner of the phone), tap the AirPlay icon in the media controls (may look like an ear icon, a triangle with lines coming out, or a Bluetooth icon), then select iPhone to switch the audio to the phone’s speakers. When you are done sharing audio, use the same gestures to direct the streaming destination back to the hearing aids.
- Android: Swipe down to open Quick Settings, then tap Media Output (if available) to select a different audio destination. If not shown, use the media app's notification to change the output. On some Android phones, the Media Output option can be accessed by pressing the volume up or down button on the side of the phone. In the system volume level slider that appears, there should be 3 dots or a graphic at the bottom indicating that media is playing. Tap on that icon at the bottom to access the Media Output option.
- To return audio to your hearing aids, follow the same steps and reselect them as the output.
Try using the Balance slider in the Rexton App while streaming. Move it toward Sharp to enhance treble, or Soft to reduce it. For more detailed sound adjustments, contact your Hearing Care Professional.
If you’re streaming via LE Audio or Bluetooth Classic, system-level audio settings or EQ apps on your phone may also influence sound quality.
Yes, certain Rexton hearing aids allow you to answer or end calls by pressing a button or using a tapping gesture on the hearing aids. This depends on the phone and hearing aid compatibility.
For iPhone 11 and newer, the feature works with supported Rexton BiCore and Rexton Reach hearing aids updated to the latest firmware.
On Android devices, this function is available when using Rexton Reach with compatible firmware and phones that support LE Audio.
For all phones, if using Rexton Reach R Plus, answering/ending calls via hearing aid controls is available as long as the hearing aids and phone can pair via Bluetooth Classic.
If your hearing aids and phone support it, you’ll be able to manage calls directly without needing to touch your phone. If you are unsure about hearing aid and phone compatibility, check with your Hearing Care Professional.
It depends on whether your hearing aids support HandsFree calling. If they do, your voice will be picked up by the hearing aid microphones, allowing you to keep your phone in your pocket during a call.
If HandsFree is not supported, the phone’s microphone will be used instead. In that case, it’s best to keep the phone in front of you and close to your mouth, similar to using speakerphone, so the other person can hear you clearly.
For iPhone 11 and newer, Rexton BiCore and Rexton Reach on the latest firmware will have HandsFree capabilities.
For Android, Rexton Reach on the latest firmware when used with LE Audio compatible phones will have HandsFree capabilities.
For all phones, if using Rexton Reach R Plus, HandsFree is available as long as the hearing aids and phone can pair via Bluetooth Classic.
If you are unsure about hearing aid and phone compatibility, check with your Hearing Care Professional.
This may happen if your hearing aids are using HandsFree mode and picking up background sounds through their microphones. Here’s how to reduce it:
iPhone:
For hearing aids that use Bluetooth Low Energy (MFi) for streaming calls:
If HandsFree is active, you can disable Mic Input in the MFi menu. Triple-click the Side button to open it, tap on your hearing aids to expand the menu, and toggle Mic Input off. This routes your voice through the iPhone microphone instead, which better filters background noise. Remember to keep the iPhone close to your mouth if Mic Input is off.
You can also enable Voice Isolation during a call (iOS 16.4 or newer). While in a call, open the Control Center, tap the orange mic icon, and choose Voice Isolation to filter out surrounding noise. You can also enable this option by going to Settings > Accessibility > Audio & Visual > Add Voice Isolation > toggle this on. Do note that with MFi hearing aids, Voice Isolation will only be available during calls for iPhone 14 Pro, iPhone 14 Pro Max, or iPhone 15 and newer.
Android:
If you're using a phone that supports LE Audio, switching back to the ASHA protocol may help. This moves voice pickup back to the phone’s mic. Keep the phone near your mouth, similar to speaker mode.To disable LE Audio, go to Bluetooth Settings, tap the gear icon next to your hearing aids, and turn off the LE Audio option.
Reach R Plus hearing aids
iPhone:
Use Voice Isolation during calls (iOS 16.4 or newer). Swipe down during a call, tap the mic icon, and activate Voice Isolation. This filters background noise for clearer calls. You can also enable this option by going to Settings > Accessibility > Audio & Visual > Add Voice Isolation > toggle this on.
Android:
HandsFree mode can’t be disabled. While some phones offer native voice filters, we haven’t found options that work during streaming to Reach R Plus.
If call quality is poor, try switching the call to speaker or the phone's earpiece using the in-call screen.
To stop calls from streaming to your hearing aids entirely, go to Bluetooth Settings, tap the gear icon next to the hearing aid listing without the "LE_" prefix under Paired devices or Media devices, and disable Calls
iPhone (for Bluetooth Low Energy/MFi hearing aids):
- Go to Settings > Accessibility > Hearing Devices > Call Audio Routing
- You can set either Call Audio or Media Audio to Never Hearing Devices. That type of sound won’t route to your hearing aids by default, but can still be selected manually during use. To turn off all streaming in the Hearing Devices menu, tap on the hearing aids listed as Connected. Turn off the Stream to R and Stream to L options in the following menu. This way, you can maintain a Bluetooth connection to the hearing aids for remote control purposes (e.g. Rexton App remote control) but streaming will not be available to the hearing aids.
iPhone (Bluetooth Classic hearing aids):
- For media audio, there is no default setting. To prevent media from routing to the hearing aids, either turn off Bluetooth or disconnect the hearing aids in Settings > Bluetooth. Tap the “i” icon, then Disconnect.
- For calls, you can set routing to Speaker in Settings > Accessibility > Touch > Call Audio Routing.
Android doesn’t let you set a default, but you can switch the audio routing during calls or media using the call screen or pull-down media control panel.
Android (Bluetooth Classic hearing aids):
Go to your phone's Bluetooth menu (e.g. Settings > Connections > Bluetooth) and tap on the device details icon to the right of the hearing aid pairing without the "LE_" prefix (i.e. the gear icon). In the device details menu, use the appropriate toggle to enable/disable Calls or Audio streaming.
No, voice assistants like Siri, Bixby, or Google Assistant can’t be triggered by pressing or tapping the hearing aids. Use your phone’s mic or onboard controls to activate them.
No, playback controls (like pause/play) can only be done directly on your phone or through the app you’re streaming from.
