One of the most useful microphone accessories is the pop filter. It is a layer of nylon stretched over a circular frame with an adjustable mounting bracket so that it can be attached to a microphone stand. The purpose of the pop filter is to shield the microphone from a burst of air pressure sometimes caused when singers sing words beginning with "p" or "b". The sensitive microphone will "clip" when the air hits the sensitive internal membrane. Musician's Friend has every kind of microphone accessory you need including Pop Filters, Microphone Shock-mounts, Microphone Clips, and Microphone Windscreens and Grilles. We offer a variety of accessories including On-Stage Stands Microphone Accessories.
