T-SIGN is both functional and stylish as well as easy to install, the kind of obvious product that makes you think 'why didn't anyone come up with this before?!.”

- Jonas Backman, Norconsult AB

T-SIGN is working exactly as intended, and both priests and deacons in the church are beginning to understand how to interpret it. It seems that even those who do not use hearing aids are more satisfied with the sound in the church now."

- Eyolf Berg, IVSS Churchear Norway

"T-SIGN provides invaluable help. I give you an example. Last week in a conference, I thought the sound began to sway on the lecturer. Thanks to being confirmed by T-SIGN, I got up and fixed the microphone on the lecturer. It turned out that it didn't quite sit as it should. T-SIGN confirms status of the hearing loop and makes everyone act faster. I spread information T-SIGN everywhere I go!"

- Susanne Nyberg, Hearing aid wearer and program manager at HRF (Hearing Organisation in Sweden
