I'm trying to share an audio file with someone who is using an iPhone. I have always used Android so I'm unclear about a couple things. When I first sent the file, it was in .wav file. Was told that it didn't play. Sent it in .mp3 and was told that it didn't play. The other user then downloaded one or the other while on the computer and was able to listen after syncing with the iPhone.

The other user is abroad without the computer and I would like to share another file.

How can someone download an audio file on an iPhone and play it without syncing? Surely this is possible.


EDIT: got it figured out with a buddy. Problem is using fb messenger to share audio files was causing an error. Dropbox works fine.
