These are real hearing aids, not amplifiers .There’s a difference. There’s also a huge difference in the cost between amplifiers and actual hearing aids. For the cost, these are not bad. But they do get somewhat “screechy” if turned up too high. In my opinion, these are great for people with slight hearing loss. If you have severe hearing loss and cannot afford actual hearing aides, then these will help to a certain degree. They are super discreet which is fantastic (see pic…you can’t even tell I have them in)!! Also, they’ve got to be charged and they’re not Bluetooth. Overall a good product, just do not turn them up too high, and make sure to fidget with them until they’re properly aligned/fitted in your ear canal
