This is a shock mount for large diaphragm condenser microphones. The RODE SM6 is a studio suspension shock mount designed to isolate your 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). ・ When used in combination with RODE large diaphragm condenser microphones, such as the NT1 Signature Series, it enables clear recordings. It hasn't been used much and is in very good condition.
