The Sony C800G is a high-end tube vocal microphone. The mic was made popular for pop and R&B production by users like Dr. Dre, Mariah Carey, R. Kelly, Kelly Clarkson and many others.

Sony’s C800G capsule is based on the Neumann K67 design. Both are large-diaphragm, dual-diaphragm, center-terminated capsules; the C800G capsule retains the K67’s characteristic backplate drilling pattern.
