@intlsubband Sony did it in 2009 with the NWZ-X1050 which had on-board noise cancelling technology.

Yeah... That's not how that worked. For the Sony implementation the mics were on the earphones. Proprietary connection to the dap. ANC processor on the DAP. Flawed concept for many reasons I can't be bothered to write down.
The mic on the dap idea is impossible. You need high coherence between mic and anti-noise generator i.e. Speaker.
