Invisible Hearing Aids

Also known as IIC’s

Below is a list of the latest IIC hearing aids going into 2019

Custom made invisible-in-canal hearing aids are colloquially known as IIC’s.

As a result of new micro-components being designed and the use of the latest 3 dimensional computer aided design and 3D laser printing technology IIC digital hearing aids are now being made smaller than ever before and also more precise fitting results.

Some IIC (invisible in canal) hearing aids may now be made as ‘wireless compatible‘ – BUT this may compromise the size of the hearing aid to the point they are not actually IIC’s. (‘Wireless compatible’ meaning being capable of streaming wireless audio signal – more info here).

Signia Silk

Signia Silk is a modular (off the shelf) hearing aid, available in three technology levels, that can be fit to differing losses and patients ear size using different click domes that fit onto the end of the hearing aid. The only gain over custom products is that they are quick to fit, and they may suit a high frequency loss well due to reduction in occlusion.

Unitron ‘Iinsera’ Micro IIC / invisible hearing aids

The Unitron Insera Micro IIC hearing aid is made on the same production line as the Phonak Virto Nano and Titanium, using the same technology and the same people, and even the same chipset. The difference is in the programming of the chipset, and Unitron Insera Micro IIC is an excellent hearing aid.
