FAQs & How-Tos
Why can't I hear my teammates?
Make sure the volume control on the headset is turned up. Rotate the volume wheel on your headset to increase the volume. If you're connected to the PC via USB, check that the default communication device is selected under Control Panel > Sound > Playback. Select JBL Quantum ONE Chat, right-click, and select "Set as Default Commuication Device". Check your headset's game audio chat balance dial, and ensure that the balance is correct. Check the JBL Quantum ONE Chat device and make sure it is not muted or turned all the way down.
How can I switch between Active Noise Cancellation, Smart Ambient (TalkThru) and off?
Onboard Adaptive Noise Cancellation is controlled by the multi-function button on the rear of the left ear-cup. Switched on by default, you can SHORT press the multi-function button to toggle from ANC to talk-through. Turn off ANC by long-pressing the multi-function button.
What is included in the JBL Quantum ONE headset box?
The JBL Quantum ONE box includes the headset, detachable microphone, calibration microphone, USB Type A to C cable, 3.5mm cable and game audio chat balance dial.
Does JBL Quantum ONE provide mic monitoring (side tone) feature?
Yes. You can configure the volume of the mic monitoring in JBL QuantumENGINE. The default setting of the mic monitoring is "OFF”.
Microphone Sound or Distortion IssuesMake sure both the QuantumENGINE software and the headset's firmware is updated to the most recent version, and that the microphone is plugged all the way in.
Why are my headphones shown as “speakers” on Windows?
The “Speaker” mode allows the JBL QuantumENGINE to receive more than two channels of audio. It also prevents some applications from adding extra signal processing intended for other headphones, which would negatively impact the performance of the JBL QuantumSURROUND or JBL QuantumSPHERE 360 technology.
Can I use the Game-Chat balance dial on my headset with all connections?
The Game-Chat balance dial only works when your headset is powered on. Please note that it supports connection with a USB Type A to C cable and a wireless transmitter dongle, but doesn’t support connection through a 3.5mm cable or Bluetooth for mobile games.
Why do I need to use the calibration microphone included with my JBL Quantum ONE?
We believe the baseline performance of the QuantumSPHERE technology is cutting edge in terms of localization. The calibration feature improves upon this performance by calibrating the system to your individual anatomy.
The volume level on my headphones is very quietIf your volume level is quiet, make sure that the TalkThru is not activated on your headphones. In order to deactivate or activate TalkThru, quickly press the ANC button located at the top of the LEFT ear cup. You will hear an audible voice stating, TalkThru On when activated, and 'ANC On' when deactivated.

Therefore, we designed the mic to fold neatly into the headset - this design also allows the mic to automatically mute when elevated. If you're wanting a detachable mic, please check out the Quantum 100 or the Quantum ONE.

Do I need to calibrate the head tracker sensor?
The head tracker in the Quantum ONE uses your movements to calibrate the sensors. You can speed up the calibration process by doing the following: * Imagine that the headphone is a standard cube with 6 faces (Front, Back, Left, Right, Top, Bottom) * Orient the headphone so that it is sitting on each face of "the cube" sequentially. For example, start with the headphone positioned normally (bottom face of the cube down). Then rotate it so that the right side of the cube is facing down. Then continue through the rest of the faces of the cube. * Hold the headphone in each position for 1 second * Once all the faces of the device have been rotated, set the headphone down on a stationary surface for 2 or 3 seconds.
EQ Settings and Surround InformationIn order to adjust your EQ settings you must follow these instructions: In your Windows 10 taskbar, right click on the volume icon. It should bring up your selected output device. If “Speakers (JBL Quantum *model* Game)” is not selected, please proceed to the next step.
In the upper right hand corner, select the arrow. This will display a list of output devices on your PC. Please select “Speakers (JBL Quantum *model* Game)” After selecting 'speakers' you will now be able to adjust your EQ settings to your preference.
The audio is not centered to my monitor, what should I do?
You can either press the recenter button on the headset or on QuantumENGINE. Ensure that your head is perpendicular to the monitor before pressing the recentering button.
Does the JBL QuantumONE calibration mic calibrate both ears?

What’s the difference between JBL QuantumSURROUND and JBL QuantumSPHERE 360?JBL QuantumSPHERE 360 is JBL QuantumSURROUND that’s kicked up a notch by using a head-tracking sensor to fix sounds in 360 degrees of space around you. With typical headphones, when you move your head, the soundscape follows your movement. But with JBL QuantumSPHERE 360, if you rotate your head, the sound source’s perceived location stays in place because the head-tracking sensor compensates for your head movement. For example, if there’s a sound coming from in front of you, and you turn your head to the left, the sound source’s perceived location moves to your right ear—the sound stays locked in space as you move your head.
Also, the human brain uses small head movements to distinguish if sound sources are behind or in front of us. The brain processes the differences between when a sound arrives at the left vs. the right ear to determine where the sound is located. So with JBL QuantumSPHERE 360, you can move your head naturally to pinpoint the exact source of sounds around you.
JBL QuantumSPHERE 360 is only available with the JBL QuantumONE gaming headset.
