PSB M4U replacement headband (simple)

I totaly love the PSB m4u 2 headphones, but unfortunately the construction is really bad.
What started as cracks ended up in a broken headphone. since it's no cheap headphone and i'm having trouble finding a successor it was time for a quick fix since i use them every day.

It's a near perfect fit now, screws will fit and the head piece will click in place and stay there ;)
