If those expensive Oticon hearing aids are not working for you, it might be worth letting your current audiologist fit you with a stronger set. Try them to see if it makes a difference. If that doesn't make a positive difference, your hearing loss may have dropped to the level where a cochlear implant would be something to think about.

Regardless, ask for a copy of your audiogram from that audiologist so you have it for comparison should you choose to go elsewhere. It's OK to take an audiogram to a different provider, including to Costco. Let that different provider test you so you can see if the tests show the same results. If an audiogram at Costco shows the same results, it could make sense to try a Costco product. It's like any other product though, you have to try it to know.

Sensorineural hearing loss tends to be progressive, so learning that your hearing acuity has dropped is not unusual.
