Here is a youtube video I just uploaded showing what I am trying to explain. You can see the difference in the end of the plug. Some of my other power supply plugs do have the extended insulator but only two or three out of maybe fifty.

OK now I know what you are talking about.
I just checked in our stores and had a look at the concentric plugs then had a chat with my repair tech.
Unless the PE has some very strange headphone socket that we have not seen, there is no way that you will get voltage into the sound circuit with either type of plug. The worst thing that could happen is to have a plug that has a barrel longer than 9 mm (edge length), in which case it will bend the innermost contact and so make using the socket for headphones rather unreliable. The solution to that is to use a small length of sleeving to reduce the inserted length to 9 mm.
Edit: Just to add pictures of a 12 mm long plug with a sleeve fitted to reduce length to 9 mm (sleeve in red).
