he JBL Quantum 300 is engineered to deliver precise, immersive audio for gamers seeking both comfort and versatility across platforms. At its heart are custom‑tuned 50 mm dynamic drivers that span a frequency range from 20 Hz to 20 kHz, providing rich lows, clear mids, and crisp highs that allow you to detect subtle in‑game cues like footsteps, reloads or ambient movements. The headset’s 32‑ohm impedance and sensitivity rating ensure it performs solidly with typical gaming systems without requiring additional amplification.

Built for extended sessions, the Quantum 300 features lightweight construction (approx. 245 g) with a sturdy yet comfortable headband and plush memory‑foam ear cushions. Memory‑foam padding wrapped in soft material ensures minimal fatigue even during long gaming marathons. The ear cushions are removable, making maintenance and cleaning easier over time. Communication is handled with a directional “flip‑up” boom microphone that mutes itself when raised—perfect for friendly banter or competitive team chat without intrusive noise.

When it comes to platform compatibility, the Quantum 300 stands out for its flexibility: it connects via a 3.5 mm audio jack, making it compatible with PC, Mac, PlayStation 4/5, Xbox One/Series X|S, Nintendo Switch (docked or handheld), mobile devices, and VR systems. On PC, an included USB audio adapter unlocks additional software features such as “JBL QuantumSURROUND” spatial sound and customization through the JBL QuantumENGINE software—giving you virtual 7.1 surround sound, EQ profiles, and more options for tailoring your audio.

Moreover, the design emphasizes gamer‑friendly details: a fabric‑covered cable for durability, quick‑access mic mute (via flip‑up), and an adaptable interface that lets you stay connected whether you’re gaming on a console, PC, or mobile platform. The result is a well‑rounded headset that balances audio fidelity, comfort, and multi‑platform versatility—ideal for gamers who want solid sound, clear communication, and hassle‑free connectivity.
