Just guessing, but they might mean that designing and manufacturing entire digital-to-analog conversion system from scratch is expensive. But using Bluetooth SoCs and off the shelf DACs can be cheaper and therefore "surely easier"?
- dfox 2y agoLightning headphones boil down to the MFi chip and cheap USB sound card (think PCM2904). Apple even provides combination of these two functions in single package. Lightning is essentially a combination of two USB HS channels on one connector, one upstream and one downstream.
