Here is a step by step of how i painted my Grado SR60s.
First up, the materials:
Step 1: Opening the Headphones.
I used the steam method.
This involves putting the headphones over hot water in order to heat the heat-sensitive glue. After a few minutes, just pull them out.
Separate the cups from the driver housing.
Step 2: Painting.
Before painting, I noticed that the rings just fall out when you apply any pressure. I flipped them and sanded the surface to make it smooth.
Before painting, make sure to give the cups a decent clean with methylated spirits or other cleaning agent.
Spray lightly and evenly. I used 3 coats of paint.
Step 3: Finished Product.
Now is the time to add other effects. I was planning on a custom grill but I couldn't find any wire to suit.
