Ambient Recording EMP4S Reviews
Great for adapting to XLR

On the advice of the B&H audio support tech, I picked this up to adapt my Shure headset mic for my audio interface that I use for voice control on my computer. I didn't realize that you would need to change the power form for the microphone to operate properly, but this does the trick and produces a very clean sound (there's no longer a slight background electronic buzz that my XLR dynamic mic had even with mic booster and gain lowered). It's pricey but necessary and ultimately worth it for my use. Plus, it's cheaper than picking up even most used Shure transmitter and receiver packs and you don't even have to worry about batteries. So if you want to use a Shure-ending mic where you're stationary, this is probably what you want.
