The Pyle PSMRS11 high-performance isolation shield with sound dampening foam surrounds your microphone and impedes unwanted sounds from contaminating your recordings. The shield creates an acoustic boundary around the microphone that improves vocal sounds by preventing room reflections from directly entering the microphone recording zone. Achieve more rich, crisp, clean sounds preferred by music professionals and deliver studio-quality performance. The shield is easy to use and install. It works equally well with round-base stands and tripods. Unwanted outside audio interference is reduced along with noise reflection by the high-density open-cell acoustic 2 inch foam liner. Effectively absorb vocal ranges, while keeping room ambiance out, to produce a dry rendering. This is particularly important when attempting to record in rooms with less than ideal acoustics or in noisy spaces.
