The Electro-Voice model 314E is designed to be used as a windscreen for models 631B and 635A microphones. It can also be used as a pop filter with the RE10, RE15, 660 and 664A microphones.
Unique open-cell Acoustifoam material adds additional protection against dust, magnetic particles, moisture, etc., while also performing its primary function of screening out wind noise and annoying p-pops.

The 314E slips over the end of the microphone easily by hand. A snug fit is all that need be checked.
