JBL Quantum Stream Overview

Designed as an easy-to-use solution for gaming, streaming, and recording, the JBL Quantum Stream is a versatile USB microphone that offers high-resolution recording, a removable RGB stand, and two pickup pattern choices. Choose the omnidirectional setting to record in a 360° circle around the mic—great for picking up multiple people—or opt for the cardioid pattern to focus audio capture more narrowly on the subject for less background sound.

The Quantum Stream supports impressive recording resolutions up to 24-bit / 96 kHz for high-quality digital audio. Plug-and-play operation via the USB connector and a convenient mute button make the mic simple to use, while the 3.5mm headphone jack allows you to monitor your audio in real time. An indenting front-panel knob controls the headphone volume; pressing it allows you to adjust the mic input gain and switch between pickup patterns. The included RGB desktop stand is especially well suited to gaming, but can be removed to reveal a standard 5/8" threading that lets you mount the mic to boom arms and floor stands.

JBL Voice Streaming Technology
Always come through loud and clear. The Quantum Stream’s dual 14mm electret condenser capsules and high 96 kHz sampling rate capture every sound for perfect voice streaming.
Two Selectable Voice Pickup Patterns
With the JBL Quantum Stream's two voice pickup patterns, you can easily switch between a cardioid mic that makes a single voice come through loud and clear and an omnidirectional mic for capturing more than one voice or even a live performance.
Universal Mounting
Mount your microphone however you want, to suit any space or situation. Three setting options and a reversible stand allow you to move the JBL Quantum Stream 360 degrees, connect it to a camera tripod, attach it to a boom arm, and more.
Voice Monitoring with Easy Volume Control
Monitor your mic voice your way. Conveniently control your PC volume directly from your headphones, from the microphone, or from your PC.
Always Know When You're on Mute
Mute or unmute with the tap of a button. An RGB ring indicator light confirms your status, so you'll always know when you can be heard.
Durable, Premium Metal Design
Stylish and sturdy, the JBL Quantum Stream is crafted with an aluminum stand, metal ring, and iron net for a premium look and enhanced stability during use.
JBL QuantumENGINE Compatibility
JBL QuantumENGINE PC-based software extends your experience beyond gaming, allowing you to adjust features like voice EQ, RGB color on the ring indicator, muting and unmuting the mic, and polar pattern selection.

JBL Quantum Stream Reviews

Will keep exploring

I'm pretty critical of voice quality and position on my desk by my keyboard, with my speakers on. This did not make the cut in terms of audio fidelity and inbound volume. When it matters I'm still having to use my headset/mic combo unfortunately. Needs probably 30-40% more volume for my voice and I'm not a quiet person. It can be compensated in tools like discord where you can boost, but not in-game situations where it's more limited so far in the month I've used it. Finish, controls, lights work fine but I prefer the minimalist ( green on, red mute ).

Awesome Purchase
