What else you need to use it
Worked out from FIFINE’s own specifications and box contents for this model. The setup builder checks the same parts against your computer and the rest of your gear.
Check first
- A USB cable. Our record of the box lists no USB cable. Check the box before you plan the connection.
Optional
- A boom arm, if you want it closer. A desk stand is in the box. An arm lets you bring the microphone nearer your mouth without it sitting in the camera shot.
When this model makes sense
- Record one voice straight over USB; get the placement right before adding effects.
- Listen through your interface’s headphone output, and play back a test recording before going live.
- Keep a simple one-voice setup without buying an XLR interface. Add one only when you need another input.
The USB versus XLR guide weighs it against the other ways to fill the same role.

Check these conditions first
Not yet confirmed from FIFINE’s documents: operating systems, dimensions. The builder treats them as unknown, never as a yes.
For a microphone, set your distance and input gain before adding any processing. Speak as loudly as you will on stream, listen back to a recording and leave some headroom. Judge a USB/XLR microphone in the mode you will use: its USB voice processing does not carry over to XLR.
What is included, and what may be missing
- K669B microphone
- Tripod stand
FIFINE’s page names the tripod stand; it does not list the USB cable or its plug.
Both cable ends and the data rating matter more than the plug shape: streaming cables and ports explains how to match them.
Place it in the complete setup
Every connection
- Webcam USB outUSB cable → A USB port on your computer
- Microphone USB outUSB cable → A USB port on your computer
- Microphone / interface headphone out3.5 mm or 6.3 mm headphone connection → Headphones (what you hear)
- Computer Ethernet portEthernet cable → router; your upload → Platform (check the stream preview)
- Wall socketThe maker’s power supply, or USB power → Computer and devices that need their own power
The diagram shows a simple USB setup. Find where the FIFINE K669B goes, then follow each input back to what feeds it and each output on to where it goes. HDMI and XLR gear needs a capture card or audio interface between it and your computer; it doesn’t plug straight in the way this USB example does.
The setup builder turns this into a connection list for your own computer and gear, and the pre-stream checklist covers the rehearsal once it is wired.
