The microphone is 465 grams and is 15cm tall and round at 5cm. It comes with a semi circular 'spit protector' - I am sure this has a technical name but I do not know it.

The three pin – in a triangle – inside the circular lead connection is in the base of the microphone.

Unlike most microphones that are at or very near the top the input is both sides with only two 1cm vertical lines to hold the unit together, but even though the other side has has pin holes the spit protector one side is the main input.

If you look closely you can see the 1 inch dual-diaphragm capsule, providing clean, controlled low-end frequencies and smooth, detailed highs for natural audio reproduction.

SUPERIOR NOISE REJECTION - The SM4's uniform cardioid polar pattern ensures superior off-axis rejection of unwanted noise, capturing your sound source with clarity and precision. REDUCES PROXIMITY EFFECT - Designed with a large “sweet spot,” the SM4 reduces the proximity effect, offering more consistent audio quality, making it ideal for close-making vocals and instruments. INTERFERENCE SHIELDING - The SM4 microphone employs patent-pending interference shielding technology, effectively blocking RF noise from cell phones, laptops, and Wi-Fi routers for cleaner audio. INTEGRATED POP FILTER - With an integrated pop-filter and woven mesh Faraday cage, the SM4 ensures clean audio capture by minimizing plosive sounds and protecting against unwanted noise. MIX-READY SOUND - The internal pop filter of the SM4 allows for plosive and rumble-free recordings, making post-production easier and ensuring your recordings are mix-ready right from the start. RECORD WITHOUT DISTORTION - Capable of capturing sounds up to 140dB, the SM4 ensures your loud instruments come through clearly without any distortion, thanks to its high-SPL handling.
