About hearing aids

admin

There are many masters in the forum, please ask me about hearing aids.
My family members have poor hearing and it seems to be quite serious. I bought cheap hearing aids on Taobao before, but they could only hear slightly, but when I turned up the volume, it made a loud screeching noise which was inconvenient.
I've been studying for several days now and I'm still unsure how to buy a good one online, the expensive ones worry that they won't work properly and waste time, going to the store worries being cheated, my ears are very soft so I'll easily fall into others' traps if they say something.
