Completely-in-canal (CIC) hearing aids are the smallest of all the hearing aid choices and distinct from 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. This style of hearing aid has many advantages, as well as a few disadvantages when compared to other hearing aid styles.
Pros.
CICs are small and their size and fit hold several aesthetic as well as listening advantages. Due to the lack of bulk, these devices work automatically without the need for controllers and other people may not ever notice that you’re wearing a completely-in-canal unless they peer directly into your ear canal.They may be more comfortable to wear due to their custom fitting. You 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. It generally doesn’t get in the way of the telephone receiver and, because it is housed inside your ear canal, your outer ear is able to keep out wind noise. Additionally, the natural anatomy of the ear helps guide sound to the instrument, which improves the directionality of the sound.
Cons.
Smaller size means smaller batteries and smaller batteries mean less battery life. They are typically more costly than other types of hearing aids due to their custom fitting. You will also be limited to omnidirectional sound, meaning you will experience all sound as if it’s right in front of you. Completely-in-Canals are typically not recommended for individuals with adequate low frequency hearing or for people with severe hearing loss.
