YANMAI Multi-Directional Switchable High-Performance Microphone SF-900

I've owned this for about 2 years, but have only used it around 10 times.
It shows some signs of use, but there are no noticeable scratches or dirt, and it's in good condition.
It functions perfectly, and comes with the box, manual, USB cable, and all other accessories.

◎ Selectable polar patterns for different recording needs
Bidirectional (Stereo): Ideal for recording instruments and vocals.
Unidirectional: Ideal for voiceovers and narration.
Omnidirectional: Ideal for recording multiple people in meetings or ambient sounds.
Bidirectional (Front and Back): Ideal for recording conversations and interviews.

Triple Microphone Core: Equipped with a highly sensitive 14mm 3-capsule microphone core, tuned for faithful sound reproduction. This allows for flexible sound capture across a wide range of sound sources and environments, delivering exceptionally clear and natural recordings.
Multi-Noise Filter: Features a multi-layer noise reduction filter to thoroughly eliminate popping sounds during recording. It also prevents damage from saliva entering the microphone.
Volume and Mute Controls: Unlike typical microphones where adjustments can only be made on the connected device, this microphone has buttons on the unit itself, allowing for easy volume control and muting.
Anti-Vibration Structure: The stand is designed with a heavy and rigid steel construction, with the weight balanced at the legs and a thick rubber sheet on the bottom. This effectively blocks vibrations transmitted from the table, preventing interference with audio input.
Mountable on a Microphone Stand: The bottom of the microphone has a 15mm threaded hole for standard microphone stands. It can be detached from its original stand and mounted on a separate microphone stand. The 3M detachable cable is also designed for ease of use depending on your recording environment.
