Those $50 adapters have a microprocessor in them to map&#x2F;convert the eight pins to whatever signals are needed. Lightning does not have an analog audio channel, so I&#x27;d bet this adapter would also need a (simpler) microprocessor and the attendant cost. Your $30 guess sounds right, and Apple probably won&#x27;t even include an adapter as long as they include Lightning or Bluetooth earbuds. People who are fussy enough about headphones to bring their own will pay the additional $30.
