If you need a foam windscreen for these mics, this is the one to get, the real Electrovoice, not a cheap copy. This is better foam, chosen to have the right acoustic properties, and not some generic material chosen to be cheap. There are up-market 3rd-party windscreens that will also work well but you can order this one from the same suppliers as the mic, plus it's sure to be long-lasting, a good fit and most effective as it was developed to match the mics
