Your hearing aids offer flexible sound controls so you can customize your listening experience. Here's how to use them.
Using the Physical Controls
Most models include one or more buttons on the device itself:
Single press: Increase volume
Double press: Decrease volume (or cycle to next program, depending on model)
Long press (3 seconds): Switch between listening programs (e.g., All-Around, Noisy Environment, TV Streaming)
Refer to the quick-start guide included in your box for the exact button layout for your model.
Using the Companion App
The companion app provides full control over your hearing aids:
Download the app from the App Store (iPhone) or Google Play (Android). Search for "iHear" or "Matrix" depending on your model.
Open the app and ensure your hearing aids are paired via Bluetooth.
From the app dashboard, you can:
Adjust overall volume
Independently adjust left and right volume levels
Change listening programs (presets designed for different environments)
Adjust bass and treble (some models)
Set automatic program switching based on your environment
Recommended Starting Settings
If you're new to hearing aids, start conservatively:
Keep volume at 60–70% of maximum for the first week.
Use the All-Around or Standard program in most environments.
Gradually increase as your ears and brain adapt to amplification.
Programs Explained
Program | Best For |
All-Around / Standard | General use, quiet environments |

Tip: If sounds feel too sharp or harsh, slightly reduce the treble/high-frequency setting in the app. If voices are hard to understand, slightly boost the mid-frequency range.
