Disposable hearing aids offer the same qualities and features of regular hearing aids, only in this case, when the battery dies you throw them out and put in new ones, rather than just recharging the battery as you would on most other types of hearing aids. They can usually be worn anywhere from thirty to forty days until the battery dies and then they are discarded. These hearing aids are usually only available by prescription and so you will have to speak to your audiologist if you are interested in getting them for yourself.
