IMPORTANT SAFETY INFORMATION
WARNING
If you are younger than 18, do not use LIZN Hearpieces®.
Attempt to use the device for improving speech comprehension in quiet surroundings.
Attempt to infer anything about a user’s hearing ability from the change in perception experienced when using the device.
WARNING
When to see a doctor?
If you have any of the problems below, please see a doctor, preferably an ear-nose-throat doctor (ENT).
• Your ear has a birth defect or an unusual shape. Your ear was injured or deformed in an accident.
• You saw blood, pus, or fluid coming out of your ear in the past 6 months.
• Your ear feels painful or uncomfortable.
• You have a lot of earwax, or you think something could be in your ear.
• You get really dizzy or have a feeling of spinning or swaying (called vertigo).
• Your hearing changed suddenly in the past 6 months.
• Your hearing changes: it gets worse, then gets better again.
• You have worse hearing in one ear.
• You hear ringing or buzzing in only one ear.
WARNING: This hearing aid should not cause pain when inserting it.
Remove this device from your ear if it causes pain or discomfort when you insert or place it. To try again, make sure to follow the instructions. If you feel pain or discomfort again, contact the manufacturer. If your pain or discomfort doesn’t go away, contact your hearing healthcare professional. You can also report this to the FDA as an adverse event according to the instructions that appear later.
Caution: This is not hearing protection.
You should remove this device if you experience overly loud sounds, whether short or long-lasting. If you’re in a loud place, you should use the right kind of hearing protection instead of wearing this device. In general, if you would use ear plugs in a loud place, you should remove this device and use ear plugs.
Caution: The sound output should not be uncomfortable or painful.
You should turn down the volume or remove the device if the sound output is uncomfortably loud or painful. If you consistently need to turn the volume down, you may need to further adjust your device.
Caution: You might need medical help if a piece gets stuck in your ear.
If any part of your hearing aid, like the eartip, gets stuck in your ears, and you can’t easily remove it with your fingers, get medical help as soon as you can. You should not try to use tweezers or cotton swabs because they can push the part farther into your ear, injuring your eardrum or ear canal, possibly seriously.
Note: If you remain concerned, consult a professional.
If you try this device and continue to struggle with or remain concerned about your hearing, you should consult with a hearing healthcare professional.
Note: What you might expect when you start using a hearing aid.
A hearing aid can benefit many people with hearing loss. However, you should know it will not restore normal hearing, and you may still have some difficulty hearing over noise. Further, a hearing aid will not prevent or improve a medical condition that causes hearing loss.
People who start using hearing aids sometimes need a few weeks to get used to them. Similarly, many people find that training or counseling can help them get more out of their devices.
If you have hearing loss in both ears, you might get more out of using hearing aids in both ears, especially in situations that make you tired from listening – for example, noisy environments.
Note: Report any injuries, malfunctions, or other adverse events to the FDA.
To report a problem involving your hearing aid, you should submit information to FDA as soon as possible after the problem. FDA calls them “adverse events,” and they might include: skin irritation in your ear, injury from the device (like cuts or scratches, or burns from an overheated battery), pieces of the device getting stuck in your ear, suddenly worsening hearing loss from using the device, etc.
Instructions for reporting are available at https://www.fda.gov/Safety/MedWatch, or call 1-800-FDA-1088. You can also download a form to mail to FDA.
WARNING
Failure to follow these safety instructions could result in serious physical injury or damage.
Do not listen at high volume levels for long periods of time as this can lead to serious and permanent hearing loss.
