Common questions about Signia Pure 312 AX hearing aids
Bluetooth / ConnectivityDisposable BatteriesControls/AppsMiscellaneous
Choose questions category:
Can this hearing aid be paired directly to my Bluetooth TV?
No. Streaming audio from the TV requires the StreamLine TV accessory.
Is this hearing aid Bluetooth compatible?
Signia hearing aids are Made for iPhone, which means they can directly stream audio like phone calls and music. You can now also stream directly to many Android devices running on Android 11 and higher. If you don't have a compatible iPhone or Android phone, you can still stream audio to your hearing aids, but it requires buying the StreamLine Mic accessory, which creates a Bluetooth connection between your hearing aids and phone.
Does this hearing aid allow for hands-free phone calls?
If you have an iPhone 11 or newer, running on iOS 15.1 or newer, and the 3, 5, or 7 AX model, you're able to talk on the phone hands-free. With all other phones, hands-free phone calls will only work via the StreamLine Mic accessory. When talking on the phone, you'll hear the caller through the hearing aids, but in order for them to hear you (and for you to use the phone truly hands-free), you'd need to use the StreamLine Mic accessory, which has a microphone on it that will pack up your voice so the caller can hear you.
How will I know when it's time to change the battery?
About 20 minutes to an hour before your battery quits, the hearing aid will play a low battery notification of steady beeps or a melodic tune. Your hearing provider can demonstrate this sound for you in the fitting software so you know what to expect.
How long do the batteries last?
Battery life varies depending on numerous factors, but you should expect 4-6 days from a battery.
Are the batteries hard to change?
For most people, no, the 312 battery is not hard to change. If you're concerned about this, you may want to check out one of Signia's rechargeable models, so you don't have to change the battery.
How can I control this hearing aid, and which settings can I control?
Using the onboard pushbutton, or the miniPocket remote, you can control the volume and program. Using the Signia app, you can control volume, program, base and treble, and on 5 and 7 models, you can control the directionality of the microphones, helping to reduce background noise in a challenging listening environment.
How do I turn this hearing aid on and off?
To turn the hearing aid on, simply close the battery door. Opening the battery door will turn the hearing aid off.
Does the app have a “Find My Hearing Aid” feature?
It does not.
Is this hearing aid CROS compatible?
Yes, all models and technology levels are compatible with the CROS Pure 312 AX.
Can I get this hearing aid with a telecoil?
No. If you want a 312 battery RIC from Signia that is tcoil compatible you'd have to get the previous generation 312 X model.
Is this model compatible with color changing kits?
Yes. If you're unsure of the color you want to order, or would simply like to change colors, your hearing provider can order color changing kits from Signia. They can then quickly change the color of the hearing aid.

Plug it into the back of your TV or soundbar and the audio will be streamed directly to your hearing aids. Others can keep the TV at their preferred volume level, while you set your own volume via the app or on the hearing aids themselves.

StreamLine MIC has two features. First, it's most commonly used as a Bluetooth streamer that allows you to stream audio from your phone to your hearing aids. If you have an Android phone or any non-Apple smartphone, you'll need this device if you wish to stream audio from your phone to your hearing aids. If you have an iPhone, you won't need this device, because Signia Pure 312 AX hearing aids are directly compatible with iPhones. Even if you have an iPhone, it still may make sense to get this, because it does allow for hands free phone calls. Wear it around your neck and the microphone picks up your voice for the person on the other end of the call to hear, so you don't have to hold you the phone to your mouth when speaking. The second feature of StreamLine MIC is its ability to work as a remote microphone. If you have a hard time hearing in noise this accessory is a lifesaver. Attach the StreamLine MIC to a companion's shirt and their voice will stream directly to your hearing aids. Their voice will come through much stronger than all the competing noise in the environment.

You probably don't need this. Most people use the app to control their hearing aids, but if that doesn't suit you, this remote is a simple way to control the volume and program.
