Completely-in-canal (CIC) hearing aids are the smallest of all the hearing aid options and different than other possibilities because they are custom fitted to the inside of your ear canal to amplify sounds in individuals with mild to moderately-severe cases of hearing loss. CIC hearing aids offer several pros for the wearer, as well as a couple of cons that you should be aware of before getting one.Pros:This type of hearing aid is small and comfortable, which provides both cosmetic and listening benefits to the wearer.Because of their small size, it’s difficult for others to notice a CIC without looking for it and it works automatically without extra knobs and buttons to control. The custom fit of the device may make this a more comfortable choice because they are molded to the shape of your inner earYou can wear some completely-in-canal brands around the clock for up to several months at a time, so there is no need to insert and remove it every morning and night. Models that cannot remain in the ear are equipped with a tiny string for easy removal. Because the device is inside the ear, your outer ear keeps away wind noise and allows you to use the telephone with ease. Additionally, the natural anatomy of the ear helps guide sound to the instrument, which improves the directionality of the sound.Cons:Because the completely-in-canal hearing aids are small, they are generally less powerful and go through batteries faster than larger ones. They are generally the more expensive option because they are custom fitted to the wearer’s ear. Additionally, their tiny size doesn’t leave room for extra features, so you won’t be able to adjust the volume or experience directional sound (the sound in front of you appears louder than one that coming from somewhere else). Moreover, CICs are not powerful enough for people with major hearing loss.
