Bluetooth Connectivity Guide for Hearing Aids
A short companion video will be added here.
This comprehensive guide demystifies Bluetooth connectivity for hearing aids. You'll learn how different Bluetooth protocols work with iPhone and Android devices, master pairing and troubleshooting procedures, discover streaming options for TV and accessories, and understand emerging technologies like Bluetooth LE Audio and Auracast that are transforming wireless connectivity for people with hearing loss.
You've just unboxed your new Bluetooth-enabled hearing aids, and the possibilities seem endless. Your audiologist mentioned something about streaming phone calls and music directly to your ears, watching TV at your own volume, and even using special apps to adjust settings. You open your phone's Bluetooth menu and see a dizzying array of options. Should you pair through Settings, or download an app first?
You manage to connect one hearing aid, but the other won't pair. Or maybe both connected initially, but now they keep dropping the connection during phone calls. Your neighbor raves about streaming their favorite podcasts, while you're still trying to figure out why the TV audio only comes through one ear. The technology promises so much, but right now it feels more frustrating than freeing.
This confusion is incredibly common, and here's the reassuring truth: Bluetooth connectivity in hearing aids is genuinely transformative once you understand how it works. The challenge isn't your technical ability—it's that hearing aid Bluetooth operates differently than the Bluetooth in your car or wireless headphones.
Understanding Bluetooth in Hearing Aids
Bluetooth hearing aids don't work like typical Bluetooth devices. Standard Bluetooth would deplete hearing aid batteries in just a few hours. Hearing aids need to maintain wireless connections all day while preserving battery life for amplification and signal processing.
The three main Bluetooth protocols
- Made for iPhone (MFi): Apple's protocol allows direct streaming from iPhone and iPad. MFi uses Bluetooth Low Energy and integrates directly into iOS accessibility settings.
- Audio Streaming for Hearing Aids (ASHA): Google's Android equivalent to MFi. ASHA-compatible hearing aids can stream directly from Android phones (Android 10+).
- Bluetooth Classic: Some hearing aids use standard Bluetooth Classic, offering wider compatibility but often requiring a companion device (streamer) to bridge the connection.
Your hearing aid manual will specify which Bluetooth protocol your devices use. Many modern hearing aids support multiple protocols—for example, both MFi and ASHA.
Pairing: iPhone and Android
Pairing procedures differ significantly between iPhone and Android devices. Once successfully paired, they'll typically reconnect automatically.
Pairing Made for iPhone (MFi)
- Prepare aids: Restart hearing aids to enter pairing mode.
- iOS menu: Go to Settings → Accessibility → Hearing Devices. (NOT the standard Bluetooth menu).
- Select: Tap your hearing aids when they appear.
- Confirm: Tap "Pair" on the request (twice for two aids).
Pairing ASHA to Android
- Verify: Ensure Android 10+ and Bluetooth 5.0+.
- App: Use your manufacturer's app (e.g., myPhonak) for the smoothest experience.
- Prepare aids: Restart aids to enter pairing mode.
- Pair: Follow app instructions or go to Settings → Accessibility → Hearing Aids.
Unlike iPhones, Android phone compatibility with ASHA varies by manufacturer. Samsung and Pixel flagships typically support it, but budget models may not.
Streaming TV and Accessories
Most Bluetooth hearing aids don't connect directly to TVs because TVs use standard Bluetooth Classic. TV streamers solve this by bridging the gap.
Why you need a TV streamer
TV streamers connect to your TV's audio output and transmit audio to your hearing aids using the correct low-energy protocol. This provides crystal-clear sound directly into your aids at your preferred volume.
Troubleshooting Problems
Most connectivity problems stem from a few common issues. Try these steps before contacting support.
- The universal reset: Toggle phone Bluetooth off/on. Restart hearing aids.
- Check batteries: Low power affects connectivity.
- The "forget and repair" solution: If issues persist, "Forget This Device" in settings, delete the app, restart your phone, and re-pair from scratch.
The Future: LE Audio and Auracast
Two emerging technologies are transforming wireless connectivity: Bluetooth LE Audio and Auracast.
Auracast: Public broadcasting
Auracast enables public audio broadcasting. Imagine hearing airport announcements or museum tours directly in your hearing aids without special equipment.
Bluetooth connectivity transforms hearing aids into sophisticated wireless headsets. While protocols like MFi and ASHA can be confusing, the result—streaming calls, music, and TV directly to your ears—is transformative. Don't let technical hurdles stop you; once set up, it becomes seamless.
Frequently Asked Questions
Can I use my hearing aids with both iPhone and Android?
Yes, but typically not simultaneously. You may need to re-pair when switching between devices unless your aids support Bluetooth Classic multipoint connections.
Will my hearing aids automatically connect every time?
Yes. After initial pairing, they should reconnect automatically within 10-20 seconds of being turned on near your phone.
Why can't I connect directly to my TV's Bluetooth?
TVs use standard Bluetooth Classic, while hearing aids use low-energy protocols (MFi/ASHA). They speak different "languages," requiring a TV streamer.
