The advantages of BTE hearing aids (those that fit behind the ear) are numerous. Not only can they deliver more amplification than smaller devices, they are generally suited to all degrees of hearing losses---from mild to profound. Additionally, behind-the-ear devices are suitable for children and adults alike. They are much easier to handle, especially for those with arthritis or other dexterity problems, than the smaller hearing aids that require a custom made ear mold designed to fit inside the ear canal.
