The story behind our Quantum name
We wanted the name to reflect this futuristic inspiration married with cutting-edge technology. The Quantum name was ultimately chosen as it conjures images of both the technology aspect through the advances in quantum computing but also a very organic feel with reference to quantum physics and the science behind building upon small elements to make massive improvements.
PlayStation InformationThe compatibility for JBL Quantum models on PlayStation 5 is the same as it is for PlayStation 4 models.
All JBL Quantum headset models work through 3.5mm audio jack (aux) connected to the PlayStation controller. USB models will also work on PlayStation. In addition, the wireless models works wirelessly when connected to the 2.4GHz USB dongle.
Please note: JBL QuantumENGINE is only available on PC. Custom lighting can be set up on PC, and will carry over when connected with USB cable or 2.4GHz USB dongle.
Non-removable microphone featureWe've intentionally designed the flip-up boom mic to stay affixed to the headset. We know from experience that losing or breaking the detachable mic is never fun. 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.
How to clean your Quantum headphone
