Except people who don’t use headphones now don’t have to carry a heavier, bigger, power hungry power ADC everywhere they go.

- CamperBob2 8y agoAn ADC weighs a fraction of a gram, costs next to nothing in volume, and consumes microamperes at most when not being used. In fact, it may even be integrated on the SoC, meaning it's still present but with nothing to do. Would need to have a look at some teardown photos to be sure.

- CamperBob2 8y agoI'm assuming he really meant 'DAC' rather than 'ADC', referring specifically to the part that drives the headphone jack as opposed to the built-in earpiece transducer. Some people use the terms interchangeably for whatever reason, even though it's not technically correct.
