Welcome! You came to a helpful place. I asked the same question when I got my first pair. My AuD, whom was also female and we knew each other, said: It’s like a woman with lopsided breast wearing a single sided bra. It’s a bit crude, but it was a helpful analogy. The balance is just not the same.
When I first got HAs 12 years ago, I spent a ton of time taking them in and out to see if they helped and judge the difference. I finally decided to just leave them in and enjoy better overall hearing. I agree with whatdidyousay - you can likely manage without, but if there is any improvement and you can afford it, it could be worth it. There is also the aspect of continuing to stimulate the less responsive nerves to keep your neurons in the brain responding to sound in the worse frequencies…or something to that effect. My AuD said that is important. I have no idea about that science, so I likely stated that poorly. Good luck.
