Yes (and mentioned in greater detail in this thread earlier), you can use Apple’s own CMHeadphoneMotionManager API <https://developer.apple.com/documentation/coremotion/cmheadphonemotionmanager> to get the orientation from the IMU enabled Apple devices with the lowest latency possible, from there you can use that with any audio solution you want. For example you can use it with our iOS SDK <https://github.com/Mach1Studios/Pod-Mach1SpatialAPI> to apply headtracking data to any spatial sound or surround multichannel format and not just FOA for an example of the most direct usage <https://github.com/Mach1Studios/Pod-Mach1SpatialAPI/tree/master/Examples/mach1-transcode-example> and lowest latency design you can achieve. You can also just use the iOS app to receive the orientation and then transmit that data to whatever host device you want by using something similar to OSC and here is an open source example <https://github.com/Mach1Studios/M1-AirPodOSC> of that as well. You have some options due to Apple exposing this on SDK side unlike several other IMU enabled headphone manufacturers, <https://research.mach1.tech/posts/imu-enabled-devices/> however it should be noted you can only access this data on their iOS SDK <https://research.mach1.tech/posts/feedback-on-apple-spatial-audio/> which is the biggest limitation currently.
