SIGNIA (formerly Siemens)

Siemens Hearing was taken over by ‘Sivantos Limited’ in 2015.

Sivantos then rebranded their UK hearing range ‘SIGNIA’

Sivantos have UK HQ in Crawley, Sussex. Most products however are now imported from Poland.

In 2019 Sivantos and other leading brand Widex merged to become WS Audiology – the two hearing companies will unite their research and development but will continue to supply as two separate hearing aid brands.

WS Audiology also own the smaller hearing aid brands Audio Service and Rexton.

Signia Touch Control

This basic level app is now included within the main ‘Signia App’.

A basic remote control app that lets you change volume and programme settings for the majority of the latest Signia / Siemens hearing aids. 

This app works by emitting a very high pitch (inaudible) tone, which the hearing aids react to; thus, this app does NOT require wireless connectivity.

Can be used in place of the miniPocket remote control.
