This unique metal screen is not simply perforated but implements a slightly convex shape to redirect low-frequency air blasts to the side of the screen. This process does not attenuate high frequencies (as fabric screens can) and leaves the vocal performance completely unaffected minus any disruptive low frequency pops . The gooseneck holds its position at any angle keeping you covered at all times. And since the whole thing is made of metal it will take a lot more abuse than a traditional fabric shield. This tool is built to last.
