I'm not sure how they are doing it, but if you enable "Live Listen" mode with AirPods (basically turns the iphone into a microphone and the AirPods into a hearing aid) in iOS12 the latency is almost imperceptible. https://www.engadget.com/2018/06/05/live-listen-ios-12-apple-airpods/ https://www.engadget.com/2018/06/05/live-listen-ios-12-apple... When using this mode to listen to my TV, I can just tell that there is a delay between the real sound and those from the AirPods but it's not long enough a delay that I can't understand the speech or really bothers me. If anyone has technical info I'd love to know. As I have also witnessed that in normal application you easily have 1-2 seconds of latency. Obviously videos synchronize with it but it's not ideal for games etc. I do wonder if it's a matter of some settings the apps need to potentially set or some such. If you think about it calls are also lower latency than this .. though they use a different BT audio profile (HFP/HSP) that is mono instead of the A2DP Stereo Protocol. Last of all I was surprised Apple didn't come up with some custom protocol mode for AirPods that allows Stereo+Mic. Gaming consoles do this on 2.4GHz even with multiple controllers so it seems possible in theory (though perhaps maybe not alongside 2.4GHz WiFi? not sure). Would love more insight on all the above. EDIT: Side note to the OP, just use a lightning adapter :-)

>When using this mode to listen to my TV, I can just tell that there is a delay... That absolutely destroys it for music apps. A decent latency for music apps is under 10ms. You don't hear it, you feel it when you press a key and you don't hear the sound immediately. It prevents you from playing fast, even if you kind of adjust to it. Your brain is very sensitive to timing differences. Hit a drum with two sticks - you can hear the difference on beat and almost-on-beat very easily. And if you are trying to use vocal effects and hear your own voice delayed - that just messes with your brain. Read this article for more background on how latency affects musicians and what number are acceptable: https://www.churchproduction.com/education/latency-and-its-affect-on-performers/ https://www.churchproduction.com/education/latency-and-its-a... As for the side note - I played with my friend's iPhone, and decided to stay away from that device :) I still have an old iPod Touch which runs a looper just fine.
