A shock mount is a frame you can place a microphone in. The shock mount is made of an elastic or flexible material. This way, you don't hear shocks and ambient noise in your recordings. So you also don't hear the dancing on the floor while you're singing. You also won't hear it if someone bumps against the table during a podcast. Go for a shock mount that matches the brand of your microphone. If you record a lot of speech and want to capture the hard lip sounds of the letters P and B, choose a shock mount with pop filter.
