The QuadCast and QuadCast S are identical in build and performance. However, the S has RGB lighting support and can connect to the HyperX NGENUITY software app. Both devices are condenser microphones with three 14 mm condenser capsules inside.
I compare the HyperX QuadCast to the QuadCast S. This video includes audio tests, and a demonstration of the lighting effects enabled by the NGENUITY software.
