The proton Max is the best hearing aid I've worn. I've had two irgo hearing aids one was ergo Neil high five and the other one was Ergo six. I've had both of them for a period of over a year. Neither one of them perform as good as the bossa proton Max and terms of clarity and noise reduction. Also both of my Ergo hearing aids had to charge your case quit on me after about a year, very unreliable in terms of the charging case. There is no comparison and performance compared to the proton Max. My wife and her friend both needed hearing aid subsequently I bought two more sets. Thank you bossa for your contribution to hearing loss at a very reasonable price.
