Youll need a ratchet or ratcheting screwdriver and 2 sockets (sorry, I didnt pay attention to the sizes). Fit our bar project perfectly Had to change tips to find a good fit. Love the mute button, always nice to have when gaming and livestreaming. These slippers get a five for cuteness. The sound was decent for the price, though I dont know about the noise cancellation. Just as a sidenote, This package includes six batteries, so no need to rush out and purchase any at the moment. You cant use a 90 degree XLR connector with this mic unless you are OK with the connector body sticking out at a crazy angle. In addition, I added black silicone to some of the joints and gaps to prevent water from getting inside the tubing. Great for work and church.
