How do I fix a broken hinge on my Solo 2?

Hi guys. One of my friends gave me an old pair of (Product) RED Solo 2's. The sound still works, but the ear cushions are old. (I already know how to replace them.) And the left hinge is completely broken. Also, the left hinge's outside 'Solo' branding piece is missing, unlike the right side. The wire is just hanging there and I'm pretty scared about the wire snapping or something, so I want to fix it as soon as possible.

Any parts recommendation or tutorials will be gladly appreciated. Here is a link to the photos of the headphone's condition and problem: https://www.mediafire.com/folder/nxbeb4r... Brokolos 2 Pics

Thanks a lot!
