OK, I’d KILL for your audiogram, seriously! I may have been born with that one? But I don’t know, cuz I was 35 when I got my first PAIR of aids, and by then the audiogram was in the mild-moderate range. Flash forward to now (almost 70) and um, well, er, NOT a lot of margin in those cinderblocks now, 
Only you can decide what works best for you, but with my DECADES of walkin’ the walk, I’d recommend you get a pair of aids and adjust to wearing them. For starters, you’ll find that the quality of sound will be different than what you’re used to: perhaps a bit too harsh, loud, or things that hopefully you can have adjusted. It would be more challenging to have an “aided” ear programmed to sound exactly like the one you don’t wear an aid in, believe me!
Also, the aids talk to each other, so phone calls are stereophonically fed to both ears; ditto any streaming device (phone, TV streamer, etc.,) which is a much better listening experience than sound waves reaching your unaided ear across a room.
With my hearing loss, I’ve opted to invest time and relationship in an audiologist, but I think you could get a working solution from Costco. I wear Phonak Lumity Life aids, 312-battery (not rechargeable!). You also have to think of the lifestyle that a rechargeable will entail: you’ll need to travel with the charging base and make sure you charge up your aids daily. Battery aids give me a lot less clutter and DAYS of use, but not a lot of manufacturers still make them.
These Phonak Lumity Life 312s were released a year ago, and the sound quality is exceptional! I have two pairs now: one in “Precious Pink”, the other coming in this Friday in “Caribbean Pirate”, cuz let’s face it, that’s ME! HAVE FUN with your aids! Flaunt them!
Keep us posted as you embark on this journey. Does not matter how old a person is when they get aids! If you need them, GET THEM. Over time, you’ll be better able to discriminate between various settings, features and even makers of aids.
Just look at my audiogram and be SHOCKED that I hear SUPER well with my aids, never have a prob streaming phone calls no matter what accent or who’s talking, do tolerably well in NOISY places. I hope you have a SMASHING success with your trial and take the plunge (well, not literally into water, cuz NO aid is waterproof yet).
