Directory Permission Change Not Working

I'm sure I'm missing something quite basic here, but I'm running Ubuntu through Virtual Box on my Mac, and so I need to give my Ubuntu user read/write access to the folder shared by the host and guest systems (named sf_VB_Shared_Folder). I performed and got the following:

user@user-VirtualBox:/media$ ls -l

total 0

drwxrwx--- 1 root vboxsf 68 Aug  3 07:59 sf_VB_Shared_Folder

user@user-VirtualBox:/media$ sudo chmod ugo+rwx sf_VB_Shared_Folder 

user@user-VirtualBox:/media$ ls -l

total 0

drwxrwx--- 1 root vboxsf 68 Aug  3 07:59 sf_VB_Shared_Folder

Why are the permissions not changing?

As the directory is shared by the host, the permission change should be applied on the host system (Mac) not the guest (Ubuntu) where the folder is mounted.
The method of adding the user to the group vboxsf won't work in this special case I think because the Mac won't know about the Ubuntu user so the chmod 777 (rwxrwxrwx) is the way to go.
