Fifine K669B
Cheapest mic that doesn't hiss. Fine for testing the waters.
Houses three capsule elements, switchable between cardioid, bidirectional, omnidirectional, and stereo. The stereo mode spaces two cardioid capsules in an X-Y configuration — not true binaural, but it creates a convincing left–right image for ear-to-ear triggers without a dedicated binaural rig. Self-noise is comparable to the AT2020USB+. The main practical trade-off: it's large and heavy, so a solid desk stand or boom arm is necessary to avoid transmitted vibration.
