When playing a video (for example Amazon Prime Video) the audio is approximately a second ahead of the video. I had the same problem when playing a video on my Mac Book Air, however, I was able to correct it by using a Terminal Command that forced the use of Codec AptX (sudo defaults write bluetoothaudiod "Enable AptX codec" -bool true). I understand that iOS does not support AptX codex but ACC codex might work. I don't know how to select a codex on iOS.
