There are some issues with setting them up. You will need an audio test to determine which part of the audio spectrum you are not hearing. Hearing aids are then programmed to amplify those frequency bands where you have hearing loss. Without an audio test, it isn't clear how you would program the hearing aids. If you are just looking for something to uniformly amplify all frequencies then I guess that would be doable. As in most things is life, you get what you pay for.
