Costco’s other models (non Kirkland) are only a few hundred dollars more than the now discontinued Kirklands. You could approach this several ways. My first question is how do you know your wife has a “slight” hearing loss? Her or your impression or does she have an audiogram? If she doesn’t have an audiogram, I think that should be the first step. If you’re a Costco member, they’ll do one for free. Prices otherwise vary greatly. If your wife has an audiogram, posting it here can let us provide better feedback. To post, go to top of page, click on FORUM, then My Hearing Tests and enter the results. To summarize, you could 1)Go to Costco and get an audiogram and see what they recommend and take in any other feedback you get, 2)Try an OTC hearing aid 3)Seek a local audiologist/hearing aid provider. My leanings would be to stick with 1 or 3. 1 will likely be notably less expensive than 3.
