The tan Shure Snap-Fit Windscreen for DL4 and DH5 DuraPlex Microphones is offered in a pack of 3 and snaps into place over the mic capsule to help reduce wind noise and cut down on plosives and breath noise from the speaker. The windscreen fits the DL4 lavalier and the DH5 headset microphones and can not be used with frequency/presence caps.
