Wired Gaming Headset JBL Quantum 400
The JBL Quantum 400 are gaming headphones with a microphone designed primarily for PC play. They combine spatial audio, software customization via JBL QuantumENGINE and a control for balancing game and chat volumes. This lets you pay attention to environmental sounds while staying connected to teammates. The headphones support JBL QuantumSURROUND and DTS Headphone:X 2.0 technologies, complemented by the JBL QuantumSOUND Signature audio profile.
JBL QuantumSURROUND spatial sound can be customized on PC using the JBL QuantumENGINE software. The software also offers EQ settings, six presets, profile creation, RGB effect adjustments and microphone settings. The headphones’ audio is tuned for gaming scenarios where both subtle cues, like footsteps, and prominent effects matter. The ability to tailor sound to your preferences is appreciated by players who use different settings for different games.
The headset includes a flip-up voice-focused microphone with automatic on/off when flipped and an instant mute feature. On-headset game/chat balance control lets you adjust the mix without changing overall usage settings. The control is Discord-certified and the headphones are also compatible with TeamSpeak and other communication platforms.
For extended play, comfort comes from a lightweight headband and memory foam ear cushions. Although the JBL Quantum 400 are mainly designed for PC, they can also be used with Xbox, PlayStation and Nintendo Switch, smartphones, Mac computers and VR devices. The package includes both a USB-C to USB-A cable and a 3.5mm audio cable, covering the wired connection options for this model.
Spatial sound for gaming
JBL QuantumSURROUND creates spatial audio that helps immerse you in the game. Its settings can be adjusted in the included JBL QuantumENGINE software for PC, so you’re not limited to a single audio profile. The headphones also support DTS Headphone:X 2.0. Together with the JBL QuantumSOUND Signature, they reproduce a range of game sounds from quiet footsteps to loud explosions.
Communication under control
The flip-up voice-focused microphone is intended for communication with other players. Its position automatically turns it on or off and an instant mute is available. A dedicated game/chat balance control lets you decide what to emphasize without changing the overall headset usage. The control is Discord-certified; the headphones are also compatible with TeamSpeak and other communication platforms.
Comfort for long sessions
The JBL Quantum 400 combine a lightweight headband with memory foam ear cushions. This design is meant for comfort during long gaming sessions when the headset remains worn for extended periods. The flip-up microphone design also lets you move it out of the way when voice chat isn’t needed. In everyday use you have gaming audio, a microphone and game/chat balance control all in one headset.
Settings in JBL QuantumENGINE software
The PC JBL QuantumENGINE software lets you adjust spatial audio and other headset settings. You can change the equalizer or choose one of six presets, create profiles, set up the microphone and tweak RGB effects. This makes it possible to adapt sound and available features to personal preferences instead of using the same settings every session.
