This lowpoly microphone has only 386 faces (all of them are quads) and comes with simple blender materials so you can see how I made the renders! In the preview images you can find both Cycles and Eevee renders, topology, material preview and solid.
The materials included in the Blender file are:
Black plastic for the body and the stand
Metal for the structure of the microphone and antipop filter
A microphone procedural material (no texture needed!) with metalness, roughness and bump
The antipop filter, a completely procedural material which has transparency (and it works with both Cycles and Eevee!)
As you can see, with smart materials (like the antipop filter) you can turn a lowpoly mesh (even a plane!) into a high-detailed object!
