Not sure that's true.

"The new chip is effectively 40 times as loud, reaching more than 140 dB even at the lowest end of human hearing, 20 hertz. And that’s good enough to do the job of active noise cancellation. Just as important, it gives the technology a path to consumer products that need even more volume, such as smartphones and laptops.Certain early customers are already sampling the prototype Cypress chips, and production samples are set to ship in June 2024, with mass production set for late 2024."

Also from what I've read personal audio devices + hearing assistance devices make up the bulk of the market demand.
