Advantages of a BTE hearing aid
What is Typically least expensive Most durable have low repair rates. Can get more gadgets on it. Can use an FM System. Most power out of the hearing aid. Less likely to have feedback. Squealing that happens when sound leaves the receiver and cycles back through to the microphone. Increasing the distance will decrease the likelihood of feedback. In a BTE the microphone and receiver are fairly far apart.
