What are ITC Hearing Aids

In-The-Canal hearing aid (ITC) sits in the lower part of the outer ear, this makes them easy to use and fit comfortably. They are also slightly larger than the IIC and CIC style of hearing aids, so they use a bit larger battery, which allows them to have a longer battery life, and they can accommodate a wider range of hearing loss.

In-the-canal hearing aids (ITC) are bigger than miniature-canal hearing aids. They fit into the cavum concha, which is the lowest third of your external ear. To insert or remove a hearing aid from the ear, an ITC hearing aid can have an extraction cord for ease of removal. 

ITC hearing aids contain a 312 size battery. A typical size 312 battery lasts on average between 5-7 days; however, this also depends on how often the hearing aid is used, the severity of the hearing loss, and the technology level.

The Benefits of ITC Hearing Aids

There are multiple benefits to ITC hearing aids. They are easy to use, and they are an excellent choice for anyone, from beginners to experienced users.

They are powerful. Although they may look small, ITC hearing aids actually have a lot more power than you might imagine. This is good news for those with moderate-to-severe hearing loss, who frequently need more power to hear the frequencies that they desire.

An ITC hearing aid can be a bit more buggy than other smaller aids, such as IIC and CIC; however, ITC hearing aids are custom-made hearing aids, they should fit you snugly, and they will fully seal up your ears. This means less chance of sound leakage, which can result in feedback.

In fact, the right hearing aid will only fit to your right ear, and the left hearing aid will only fit to the left ear, you cannot exchange them. Therefore, the chance that you lose them is lower, even when you are talking and chewing.
