I don't know if you want suggestion on cheap hearing aid or best hearing aids. For high frequency hearing loss you should at least require a digital hearing aid and if you can opt for open fit hearing aids that will be best. You can discuss technology and price range with you audiologist depending on your lifestyle and listening needs.
