So here’s a probably stupid question, but I want to check myself. There are a number of IEM manufacturers that are offering IEMs with a lightning connector for iOS phones - those that do not have headphone outputs.
It was my understanding that these devices do not put out analog audio. I don’t know about the input side of things for inline microphones. But I really thought that the lightning port is a digital out port.
If so, there would have to be a DAC embedded in the connecting cord. Hiding electronics in connectors is something that Apple seems to do. Does anybody know if this is the case? If so, what DAC chip are they likely to be using and what, if any control would an end-user have?
Or am I way off base (would not be the first time) and there is analog audio out of a lightning port?
