    for behind-the-ear instruments
    A custom earmold is an important part of an optimum behind-the-ear instrument fit. It is the best way to prevent feedback (squealing or whistling) and important in obtaining a comfortable, secure fitting. With venting, it can help eliminate a plugged feeling or the sensation of "talking in a barrel."
