Buyer's Note: Causes of howling/noise: In order to make the hearing aid into a mini size, the internal amplifier is close to the microphone, and the sound is constantly received and amplified, so there is a certain possibility of howling after turning on. At present, low-power hearing aids and high-power hearing aids on the market are almost unable to avoid howling, and only full-digital hearing aids can avoid howling.
Ways to avoid howling/noise:
1. When the power is high (the amplified sound is loud), it is more likely to produce howling, so gradually increasing the volume from a small volume can effectively avoid howling.
2. When the ear canal is completely sealed, no howling sound will be produced. Therefore, please use the hearing aid after cleaning the ear canal, and try the earplugs from large to small to find the most suitable earplugs.
3. After the hearing aid enters the ear canal, it is recommended to push the hearing aid with your fingers and hold for 1-2 seconds, and then release to fully extend the earplug.
In addition: If you don't know how to use it, or there is a problem with your hearing aid, please don't rush to leave a negative comment and contact us. Thank you.
Features
1. Peak gain (dB): 30dB, suitable for mild to moderate hearing loss (refer to hearing loss chart)
2. Ultra-mini size: The earplugs extend from the ear in a size of only 0.659 * 0.0.4 * 0.23 inches, weighing only 1g, and can be well hidden in your ears.
3. Bionic design: Designed for the hearing-impaired, it fits the ear canal better. You won't feel pain even if you wear it for a long time.
4. Long working time: One A10 battery can last for about 60 hours. Convenient and practical.
5. If the earmuffs do not completely fill the ear canal or there is air leakage at the earmuffs, it will cause annoying whistling sounds. We provide 3 different sizes of earplugs to reduce whistling and noise.
6. Gift included: We will provide a hearing aid box for carrying. Each set contains matching batteries, earplugs and cleaning brushes, etc. It will be a great gift for friends or family.
