technically samsung didn't buy these brands, Harman did. And samsung has owned Harman (including JBL and AKG) since 2018.

so you should probably expect that these brands will continue operating the way that Harman, JBL,and AKG have since they were acquired. which is to say, pretty independently of anything samsung does.

Fwiw after Harman bought AKG, the Austrian engineers were laid off or left the company. There is a company called Austrian Audio that is more of a spiritual successor to AKG.
