The stencil version (non-adhesive) can also be ordered for the headphones, but it is not absolutely necessary.
 
The headphone stencil consists of 2 stencils, which is also the reason why it is a little more expensive.
Template 1 is the outer frame with the inner part.
Template 2 contains only the details.
