This might seem dumb, but does every pair of headphones need to be “smart” nowadays?

Is there anything wrong with using just Bluetooth or better yet, an AUX connection?

Am I in the minority here?

But can they post my heart rate via mqtt to a blockchain in the cloud where an AI analyzes it to send push notifications to both my health insurance and smartwatch about how I should do more sports?

I haven’t read the article, but “smart” technologies are removed.
