Choose it if…
- You want a direct USB computer input without a separate audio interface.
- You want to hear your own voice through headphones while you play.
- You can match your stand or arm to 5/8-inch thread (shock mount) · 3/8-inch thread (with the 5/8-to-3/8-inch adapter).
Before choosing this model
- In XLR mode the mute button, gain knob and headphone jack stop working; the interface does that job.
- FIFINE says it does not work on Xbox: Xbox consoles do not accept third-party USB audio devices. Its only workaround runs the mic into a computer and a 3.5 mm cable from the mic's headphone jack to the controller, and FIFINE advises against it.
- On a PlayStation with a headset in the controller, FIFINE says you set the input and output devices by hand each time you play.
- No XLR cable and no stand in the basic K688 box.
- The K688T and K688CT are this same mic sold with a boom arm: FIFINE's BM63 arm with the K688T, its CS1 arm with the K688CT.
- FIFINE's pages disagree on the 5/8-to-3/8-inch adapter: the manual lists it in the box, while the store FAQ says to use the adapter that comes with the boom arm.
- FIFINE's pages disagree on gain: the manual says the input volume cannot be set from the computer, while its PS5 article says you can use the PS5's Adjust Microphone Level as well as the gain knob.
- The K688Neo options use a different shock mount; FIFINE's spec table and manual describe the K688 with the round shock mount.
- Not compatible with FIFINE's Genie software.
- USB and XLR have different controls: over XLR, the mic's USB mute and voice processing may not work. Pick the connection you'll use in the checker.
- Check the stand, thread and desk position before ordering a mount. Include attached shock mounts and adapters in the total weight. Arms rated for this mic →
- Also needed: XLR cable and an audio interface or mixer, only if you use XLR; a desk stand or boom arm: the basic K688 box has a shock mount but no stand.
