The hearing aid appears to be from Oticon and is a behind-the-ear type, with a thin wire and a small unit inside the ear. The model number or label is not clearly visible, so the model, manufacturing year, or performance category cannot be confirmed from the image alone. IMPORTANT: The shape of the hearing aid alone is not enough to determine if it is the Opn S, More, or another model. It is necessary to photograph the label/model number inside the battery compartment or on the body of the hearing aid, or have it examined by an audiologist.
