Yeah but do they say "ess oo ess ee" or "suess"?
In English, it's "SOO-zuh" or "SOO-se" if the speaker isn't native and doesn't turn final vowel sounds into schwa like most natives tend to.
In German, it's "ZOO-ze"
/ˈsuːzə/
It is not Susie, or Suzy, or Sooz, or anything like that, and that pronunciation tends to annoy the company. Souce: me; I worked there for 4 years. The company has Youtube videos on how to pronounce it, and even a song making fun of people getting it wrong.
Think of the American march composer John Philip Sousa. Like that. As in the musical instrument the sousaphone.
And we Germans do turn the latter syllable into a schwa.
