Well you gotta remember that when ur using mic's with a huge membrane they also wil pick up background noises like.. Screaming neigbours, Cars driving past your house, Computerfans spinning etc etc
a portable vocal booth is in most of these cases a pre or you need to be able to edit audio properly with out getting clicks if u silence certain area's.
So theres a vieuw things you should look @
1. What kinda video's/audio ya make.
(for example if u make music with a huge membrane mic it's nessecary to have a vocal booth to make sure you dont get any background noise or unwanted effects created by your surroundings"like a reverb")
2.What is my audience.
(If a lot of people are comming to your channel for just watching your games they probably wont pay as much attention to the audio quality of the mic as long it's : informative, entertaing etc etc)
3.What DO YOU WANT
4. how much people need to talk in the mic in the same time.
(mic's have diffrent property in the way the record and from wich direction so if you are with 2 people running a show you should probably go for a mic that's Omni directional or other "figures" that record in more then 1 direction)
so i hope i gave enough information about what you should know about mic's BEFORE you consider on buying a certain mic.
if you can give me this information.
me and other people can have a better picture of the specs needed for your work
