Seriously, made a huge difference in the acoustics of my audio. Goes right in behind the MXL V250, keeps the room noise out, and keeps my voice from reflecting back. Bloody well couldn't do without this.
Not a substitute for proper acoustic foam, but should ABSOLUTELY be used in conjunction with it. Great gift idea for the recording artist in your life. You're welcome.
Picked this up at Guitar Center for around $50, and it's well worth the price. Good for blocking vocal reflections from whatever wall is behind the mic. I may upgrade to a much larger isolation shield later, as this one is on the smaller side.
I had a larger Auralex Mudguard mic shield, but it took up too much room on my desk. This is small and fits in my desk no problem. Probably not as good as the Auralex, but I didn't have a whole lot of options.
