If your Synvix is whistling or producing feedback, try these steps.
- Volume set too high: lower the volume, then increase it slowly.
- Microphone obstructed: keep your hands away from the microphone once the device is secure in your ear.
- Domes not inserted properly: reinsert the hearing aid so the dome sits snugly in the ear canal. Don’t force it deeper if it’s uncomfortable; contact us instead.
- Incorrect dome size: try different dome sizes for each ear.
- Earwax causing feedback: clean the microphones, hearing aids, eartips, and case; replace eartips if needed.
