The Quantum 100 is JBL's closed, wired over-ear headset for gaming, fitted with a detachable boom microphone. Introduced in 2020, it combines QuantumSOUND Signature tuning with a lightweight headband and memory foam ear cushions.
Key specs that matter
The drivers are 40 mm dynamic units. JBL states a frequency response of 20 Hz to 20 kHz, a sensitivity of 96 dB SPL at 1 kHz and 1 mW, a 32 ohm impedance and 20 mW as the highest permitted input. The cable is 1.2 m long and ends in a 3.5 mm jack, and the headset weighs 220 g.
Engineering and use context
JBL fits a detachable, voice focus directional boom microphone with mute features, intended for clear communication in multiplayer games. Its frequency response runs from 100 Hz to 10 kHz and its sensitivity is -42 dBV at 1 kHz/Pa. The boom plugs into a 2.5 mm jack on the headset, so the headset can also be worn with the microphone removed. A volume control dial and a microphone mute and unmute slider sit on the left ear cup, and both ear cups fold flat. According to JBL the Quantum 100 works fully with Windows Sonic Spatial Sound, the native surround system built into Windows 10 PCs and Xbox One consoles. The package holds the headset and its removable boom, a foam windshield for that boom, and printed papers covering quick start, warranty and safety. No splitter cable is listed among the contents, unlike on the Quantum 200.
Pairing
Over its single jack the Quantum 100 is compatible with Windows PCs, Macs, Xbox, PlayStation and Nintendo Switch consoles, mobile devices and VR headsets, and JBL refers owners to its connectivity guide for the specifics of each platform. Its modest impedance and sensitivity suit the headphone socket of a gamepad, notebook or handset.
Alternatives
The JBL Quantum 200 is the next wired model in the range, stepping up to 50 mm drivers, a flip-up boom microphone with auto on/off and echo cancelling, a 30 mW input rating, a supplied 1.5 m PC splitter and a weight of 245 g.
