I didn't know, but my grandmother had a pair of hearing aids that cost 3 million won each. (I think a relative gave them to her, but I don't remember the brand.)
And then it broke and I took it in for repairs, but since he doesn't have a hearing aid, he keeps talking and seems to be able to converse, but occasionally says, "I can't hear you well." It's been three weeks since I took it in for repairs, and my father just told me to wait since he already had it fixed.
My grandmother was really uncomfortable, so she told me to 'look into getting some cheap hearing aids'.
If there is anyone around you who has been fitted with a hearing aid, could you please recommend one?
I saw this Osstem(?) near my house, but I'm not sure if it's really that cheap.
