What are you using to record these voice memos?
OmniFocus on iOS records in Core Audio format (.caf), and QuickTime Player on the Mac knows how to play it. .m4a, .aif and .mp3 files need to be opened by another application on iOS, such as GoodReader or Air Sharing (undoubtedly there are many which will work, those are just two that I happen to have).
