ITC devices are designed for simplicity. They are custom made to fit fully inside the ear and are arguably the easiest hearing devices to use.
Due to their small size, ITCs rarely have volume controls fitted, but are able to have a programmable push-buttons. This allows you to change the way the devices work by selecting different listening programs for different situations. Devices can be set up in many different ways, but an example would be:
Program 1 = Fully Automatic (the devices will adjust themselves to adapt to your listening environment)
Program 2 = Noisy Environment (the devices will give extra noise reduction and focus on speech from in front of you)
Program 3 = Music (the devices will be less automatic, to allow loud and soft elements of music to be enjoyed)
Wireless communication between the devices allows the push-buttons to work as a volume control also, where two devices are fitted. This is achieved by using the button on one device to make both louder, and the other to make them both softer.
ITCs are not suitable for everyone as people with a sloping, high pitched hearing loss may find they feel their ears are blocked when using this style. If the size of the ear canal allows it, an air vent can be made in the shell of the device to minimize this feeling.
