Made of fur sleeve and foam, Rode's WS7 is a windscreen designed for NTG-3 and shotgun mics with a maximum length of 186.5mm and a diameter of 20mm.
A windshield's job is to provide protection from noise in adverse natural conditions while recording, and the WS7 does its job simply suberbly. With the convenient slip-on design, no more wind and handling noises will ever reach your recordings.
