Two Screen Pop Filter: The first screen blocks air bubbles like any pop filter normally would the gap in between then disperses any remaining air pressure so that once the pressure passes the second screen, it easily catches. Adjustable Gooseneck: The metal gooseneck holder supports the weight of the filter and holds it in place. You can adjust the angle and distance between the screen and the microphone. Universal Compatibility: Adjustable screw swivel clamp with anti-scratch gripper can attach to MOST tube bases or mic stands (Maximum diameter:15.5cm). How to use: Avoid the dreaded hissing and lisping sounds that come from pronouncing the letter "S" and blocking the ugly "Explosives" that follow "B" and "P". It's a great item for singers and actors alike who want help in achieving the best possible performance and to help protect against spitting all over your vocal mic. Easy Assembly and Disassembly: Swivel bracket for easy assembly. Mic Stand and Shock Mount are sold separately, not included. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
