This is a shock mount for large diaphragm condenser microphones. The RODE SM6 is a studio suspension shock mount designed to isolate the microphone from vibrations and physical noise. It comes with a removable pop filter to reduce noise caused by plosives (such as "p" and "b" sounds). ・ By using it in combination with RODE large diaphragm condenser microphones such as the NT1 Signature Series, you can achieve clear recordings. Please note that there is some dust on the net.
