- For the first time you wear the hearing aid, you'll fell uncomfortable as you never wear it before, but you will become acclimated later.
- How to get used to wearing it? Wear it a bit longer day by day, adjust the volume from low to loud, wear it in quiet environment first and then noise environment
- How to avoid squealing? First turn volume to the position of "1"; Second, plug hearing aid into your ear firmly and then turn volume to the clearest position. If the hearing aid can't fit your ear firmly, choose another earbud and try again, do not leak out air
- Note: Do not keep things close to your aid while wearing; Keep your ear clean to avoid uncomfortable sound.
