I know SonarWorks are supposed to be coming out with a version of True-Fi for iPhone and Android (I know people that have participated in the beta program). It’s very effective on the desktop, so hopefully it’ll be similarly so, with an appropriate array of mobile-relevant headphone profiles, when it is formally released.
With Apple’s latest Lightning and Bluetooth connected Ear/Airpods, the built-in DAC/processing applies EQ/DSP to deliver a better-than-simple-analog result. At least compared to their pure-analog versions run off the Apple 3.5mm dongle, or third-party DAC/amps.
