I developed a problem this year and everyone wanted me to get a hearing aid for my bad ear. I said no, because i knew that it was from something that happened quickly not over time. I finally got to see a specialist and they had it almost fixed after performing minor surgery in the office.
Hearing aids are wonderful if you need them and can't avoid it. I'd have no issues wearing one if that was the only option. My mother had a tiny one that was inserted into the ear. It was the size of a pea and prone to getting lost. Changing batteries was impossible for her.
The bigger type that you show would be my choice. My mum used to forget that she was wearing hers and would leave it on all night, draining the batteries.
