If you are truly an old fart like me you may qualify for hearing aids under the government hearing program.
I went to the audiologist with my lnearest Specsavers and bought the next level up from the basic model for $ 395 over the hearing aid subsidy.
This included 5 year maintenance and free batteries under the hearing aid subsidy, afyer that I will qualify for a new set.
Professionally tuned to my hearing needs and fantastic service from them, especially mailing out batteries during the covid lockdown last year.
