Let's play a game. No, it's fun, swear.
If we asked you to take a wild guess on what Emma Watson's ringtone is, what would you say? For us, something classical or timeless instantly comes to mind. Like, maybe Johann Sebastian Bach's "Air on G String," or maybe something from The Beatles? And it would subtly get louder as it went on, instead of just surprising you with an aggressive ring.
Don't ask us how we came to that conclusion. Watson is just classy AF, and those seem to be a good fit.
Regardless, we'd be wrong, and (we say this with kindness) your guess was probably wrong, too.
