Sivantos Group - Home - Sivantos
Says Sivantos was bought by Widex 2019
That model was released at that time. Looks like aan Evoke 440 since it has a rechargeble battery and Widex didn’t make any others at that time,
Of course I only Googled that info and with less than 5 minutes of research I could well be wrong.
