Recommendations
The user who uses the hearing aid for the first time selects the low-frequency mode in the first week or two and adjusts it to the most appropriate volume to adapt to the habit of wearing the hearing aid.
Don't wear it too long a day. Take it off and rest every 30 minutes.
After the adaptation period, try to switch modes or wear the device when talking to people, and continue to try in different scenes until you find the most comfortable experience.
After three weeks, we believe you will be very satisfied with the product. Have a nice day!
