Fifine K669B review

The K669B is the cheapest mic on this list and a simple upgrade from a laptop or webcam mic. It is a USB condenser microphone with a uni-directional pickup pattern, a 20Hz to 20KHz frequency response and a 130dB max SPL, and it ships with a tripod stand so it is ready for a desk out of the box. It draws power from USB at 5V, so there is nothing else to plug in. At $36.99 it costs less than a fifth of the PodMic USB, which makes it a sensible choice for students, occasional callers or anyone testing whether they enjoy recording before spending more. The limits are clear from Fifine's own specs: a 78dB signal-to-noise ratio, no XLR output and no onboard processing or companion app. As a condenser, it also picks up keyboard and room noise, so keep it close to your mouth. We compared documented features and published prices; we did not test it.
