USB Microphone
Allows intricate software customisation of values such as gain and whatnot, making it more versatile for more environments than the previous Yeti. The other options of same ability are XLR microphones, which require a lot more cash for a lot more parts.

Microphone Shock Mount
Have it horizontally flat, as vertically flat does not prevent shock noise.
Webcam & Microphone Arm
I tried the Rode PS1, the Blue Compass, and this, which is 1/10 of the price of the others, however this is actually better. Got one for my webcam, and one for my Blue Yeti. No issues.
Arm Microphone Adapter
Works fine to attach the shock mount and microphone to the arm.
1/4" Swivel
Works fine to attach to the arm to adjust the webcam.
