We still need to remind you that noise will be inevitable when using the hearing aid for the first time.<br> <br> Hearing aids have an adaptation period of 2--4 weeks when they are just worn. The time ranges from short to long, and the environment changes from quiet to noisy. Gradually adapt. <br> <br> And do not wear it continuously for too long a day, take it off and rest every 30 minutes.<br> <br> After the adaptation period, try switching modes or wearing the device when talking to people and keep on trying in different scenes until you find the most comfortable experience. After getting used to it, you can wear it for a long time every day<br>
