HyperX QuadCast S Review

The Design Decision: Streaming-First

The QuadCast S is designed from the microphone down for streaming use cases.

Every differentiating feature relative to the Blue Yeti X addresses a specific streaming problem: Shock mount: prevents desk vibration from keyboard typing from reaching the capsule.

During a stream, keyboard clicks picked up through the stand are audible in voice recordings.

Tap-to-mute: a single tap on the top of the microphone mutes the input and changes the LED from red (active) to red and dimmed (muted).

Audio Quality

The QuadCast S uses a condenser capsule with cardioid, omnidirectional, bidirectional, and stereo polar patterns, the same configuration as the Blue Yeti X.

In direct recording comparison at identical gain and distance settings: Frequency response: both microphones have similar overall character.

The QuadCast S has slightly more presence in the 3-5kHz range (where vocal clarity lives), the Yeti X has slightly more extended high frequency above 10kHz.

Neither difference is significant enough to prefer one over the other based on audio quality alone.

Polar Pattern Switching

The dial on the lower front of the QuadCast S switches polar patterns mechanically, you hear a click as it moves between positions.

Four positions: cardioid, omnidirectional, bidirectional, stereo.

No software required to change patterns.

This is a streaming advantage: you can change the pattern between live segments without opening an application or breaking your setup workflow.

RGB and HyperX NGENUITY

The QuadCast S adds RGB lighting around the capsule and body relative to the standard QuadCast.

The lighting integrates with HyperX NGENUITY and Logitech G Hub (HyperX was acquired by HP, which has partnerships with Logitech's G Hub ecosystem).

The RGB serves one practical purpose: if your streaming scene includes a camera view of your desk, the RGB creates visible streaming aesthetic continuity with other HyperX or RGB peripherals.

If your camera does not show your microphone, the RGB is purely decorative.

Stand and Mounting

The QuadCast S includes a desktop stand with the microphone suspended in the shock mount.

The stand positions the microphone at approximately 15cm above the desk, adequate for direct desktop use.

A boom arm produces better results for most streaming setups.

The QuadCast S uses a 3/8" thread with included 5/8" adapter, compatible with all standard boom arms.

NGENUITY Software

Polar pattern indication (shows current position, redundant with the physical dial) No real-time audio processing The lack of a noise gate, compressor, or EQ in NGENUITY is the QuadCast S's primary software shortcoming relative to the Yeti X with VO!CE.

For processing in OBS, use OBS's built-in VST plugin support with a noise gate and compressor plugin, this provides equivalent processing to VO!CE without requiring NGENUITY.

Who Should Buy It

You stream live and need reliable tap-to-mute Desk vibration from typing is a recurring problem Your streaming setup shows the microphone on camera and RGB matters You already have HyperX or Logitech G peripherals Buy the standard HyperX QuadCast if:
