Hearing aids have come a long way. One of the more recent forms Ring Ease Review of hearing devices are the hearing aids also known as open fit hearing aids. These small devices are either placed above or behind the ear. It is on this basis that they are referred to as open because unlike other hearing devices they do not block access to the ear. There are two main types of open fit hearing devices: there is the acoustic thin-tube open fit model and the speaker-in-the-ear model (SIE). In the acoustic thin-tube model, all the electrical components necessary for detecting sound are contained in a plastic container which is kept behind the ear. In this model, sound is first processed in this plastic container then transmitted into the ear through a transparent acoustic thin wire.

In the SIE model, the speaker is located at the tip of the acoustic thin wire. Therefore, sound does not have to travel through the wire to get to the ear. Because of the speaker's location, the quality of the sound is much better and this is why the SIE model is preferred for persons suffering from high frequency hearing loss and other more niche forms of hearing difficulty. One of the key advantages of open ear hearing device is their reduced occlusion effect. This effect common in non-open aids is characterized by 'tunnel-like' sound transmission due to the obstruction of the ear by the device. The open hearing aid is located outside the ear and this means the user receives the sound signals in a more natural sounding form.
