Those whines drive me crazy and I’m 34! Do any induction cooktops not have that terrible whine? At least with the duxtop portable induction I had to return it because the whine was so bad.
Which leads to the question : which ones do not have a whine? Does the breville? Or which? It’s not something any reviews I’ve seen talk about

You may want to check out those that apparently can handle non-magnetic cookware; those apparently run on higher frequencies to make up for the weaker magnetic effect.
