Let’s get you
listening.
Keep this guide nearby the first time. Start somewhere quiet with both phones in front of you.
1 Share a connection.
The two phones talk to each other directly. Choose how they connect.
On each iPhone, open Settings → Wi‑Fi. Connect both to the same network. Your home Wi‑Fi is a good place to start.
Some guest or public networks prevent devices from finding one another. If you cannot connect there, try a Personal Hotspot.
- On the phone you will listen with, open Settings → Personal Hotspot and turn on Allow Others to Join.
- On the microphone phone, open Settings → Wi‑Fi. Select the listening phone’s name and enter the hotspot password shown on that phone.
- Return to Huh? on both phones. Keep them within range of the hotspot.
Personal Hotspot availability depends on your carrier and plan. Other activity on a connected phone may use cellular data.
2 Get Huh? on both iPhones.
On each iPhone, open gethuh.com/get and follow its two taps: get TestFlight, then Open Huh? in TestFlight and Install. No code is needed; if TestFlight asks for one, go back to that page and tap the blue button. Both phones need iOS 17 or later.
Allow Local Network access when Huh? asks. The phone acting as a microphone also needs Microphone permission.
3 Connect what you listen with.
On the listening iPhone, connect your hearing aids, AirPods or earbuds the way you normally do. AirPods and earbuds use Settings → Bluetooth. Made-for-iPhone hearing aids use Settings → Accessibility → Hearing Devices.
Huh? plays through whatever that iPhone is using for sound. Play a moment of music first to check it reaches your ears.
4 Choose who does what.
On your listening phone, tap I want to HEAR. A six-digit number appears.
On the phone near the person speaking, tap I want to BE HEARD. Let everyone nearby know this phone will send live audio, then enter the six-digit number. The sixth digit starts the connection.
5 Check the sound together.
Place the microphone phone near the person speaking and keep it visible. Speak normally and make sure the listener hears the live sound. Begin at a comfortable volume and adjust with the listening iPhone’s volume buttons.
If a phone speaker feeds back into the microphone, lower the volume, move the phones apart, or use earbuds or hearing aids instead. If you hear an echo or doubled voice, try a different placement.
6 Take a break when you want.
The listener can tap Pause, then Resume to listen again without entering a new code. Pause silences listening; it does not necessarily turn off the other phone’s microphone.
The microphone phone has Mute and Unmute. Mute stops that phone from sending microphone audio while keeping the connection. The microphone may remain active, and iOS may still show its microphone indicator. A listener’s Pause and a speaker’s Mute are separate choices.
Tap Stop to end the audio stream. Keep the microphone phone in Huh? and visible while you use it.
+ Only one phone? Just this phone.
Coming in version 1.4. Connect your earbuds or headphones first, open Huh?, and tap Just this phone. Set the phone down near whoever is talking. There is no code and no network.
Sound only plays through earbuds, headphones or hearing devices, never the phone’s speaker, so it waits until they are connected. Bluetooth reaches about 30 feet (10 m) in the open and less through people and walls, so sit near the front. For more distance, use two phones. Hearing devices with this mode are still being tested; if yours connect but Huh? still asks you to connect first, use two phones for now and tell us your model.
Something not working?
Start with the connection and audio checks. A phone call or audio route change can interrupt a session; check both screens after it ends.
