Headphones
The whole thing fits in two `if` statements. One for the cups, one for the band. Minimalist design for a minimalist solution ┗(^0^)┓

Solution
a=abs(x)
b=abs(z)
if b<3 and y>-5 and y<1 and a>4 and a<8 then
return a<6 and 3 or a>6 and b<2 and y<0 and y>-4 and 5 or 4
end
if b<2 and y>-1 and max(y,a,a+y-3)==6 then return 4 end
How it works
Two parts: the ear cups and the headband.
The ear cups are symmetric boxes at abs(x) between 5 and 7, spanning y from -4 to 0 and three voxels deep in z. A single ternary chain handles all three layers: the innermost face (a<6) is BLACK for the speaker grille, the outermost face (a>6) gets a PINK cushion in the center (where both z and y are close to the middle), and everything else is PEACH plastic.
The headband arcs over the top using max(y, a, a+y-3)==6, which is a neat trick. It defines a chamfered shape: a flat top at y=6, vertical sides at a=6, and 45-degree bevels where the band curves down to meet the cups. The ==6 makes it a thin shell rather than a solid block, just one voxel thick all around the arc.
