Meet the BOYA CastMic G40, designed to elevate every match and stream. Bold RGB lighting energizes your gaming setup, giving every moment immersive visual impact. With noise cancellation, ultra-focused voice capture, easy USB plug-and-play, and intuitive onboard controls, the BOYA CastMic G40 keeps your communication clear and your gameplay fully in control—from casual sessions to clutch moments.

• Feature 1：Studio-Grade Sound for Every Whisper & Shout

Designed for a studio-quality sound experience, the BOYA CastMic G40 features a 14 mm large-diaphragm condenser capsule delivering high-resolution 192 kHz / 24-bit audio. With powerful 125 dB SPL handling, it captures everything from soft whispers to triumphant shouts without clipping or distortion. An 85 dB signal-to-noise ratio ensures clean, accurate sound while effectively reducing background noise.

• Feature 2：Thoroughly Block Out Noise

Four-layer noise reduction keeps your voice fully protected. The BOYA CastMic G40 features a built-in DSP chip for noise cancellation, which can be activated with a long press on the top. Its supercardioid dynamic capsule effectively suppresses sound from the sides and rear. Combined with an anti-vibration shock mount and pop filter, the G40 minimizes noise caused by movement, vibrations, and plosives, reducing distractions from keyboard clicks, distant traffic, or household sounds. Your squad hears your callouts, not your room.

• Feature 3：Ignite Your Stream with RGB Lighting Display
  

It’s a powerful tool designed to help you stand out on streaming platforms. Enhance your setup with 9 dynamic RGB effects and sound-reactive lighting. The immersive visuals create a more engaging gaming atmosphere, making your streams and videos more compelling. All lighting effects are switched directly via a dedicated button button on the microphone body—no software or app required.

• Feature 4：Master Gain, Monitor & Mix
  

Two intuitive knobs let you adjust microphone gain and headphone monitoring volume independently. But what if you’ve already set the perfect overall level, yet the game audio or voice chat still feels too quiet or too loud? That’s where the mix knob comes in. It lets you balance voice and background audio in real time—without affecting what your audience hears. Turn it clockwise to boost game audio, or counterclockwise to emphasize your voice. With these dials, it’s easy to make your teammates sound clearer on Discord or any video call app, or create a more immersive experience by raising the game sound.

• Feature 5：Tap to Mute, Stay on Track

Control your audio presence with the precision and confidence broadcasting demands. A simple tap on the mute button at the top of the microphone instantly mutes or unmutes the mic, keeping audio control silent and effortless. The LED indicator shows your status at a glance, turning red when muted. In addition, the built-in 3.5 mm jack lets you monitor your audio in real time with headphones.

• Feature 6：Flexible Connectivity for Every Creator

The USB plug-and-play design works seamlessly with the included USB-C to USB-C / USB-A dual-connector cable, allowing easy connection to PCs, tablets, and phones. No extra drivers or software are required, ensuring a quick and hassle-free setup across multiple devices.
