These in-ear headphones feature QuantumSOUND Signature technology for immersive audio and a Voice-Focus inline microphone with a mute button. Twistlock technology ensures a secure fit during long sessions, while the 3.5mm connection offers lag-free compatibility with PC, PlayStation, Xbox, and mobile.

The JBL Quantum 50 Wired Gaming Headset with Mic – 3.5mm Jack – Black is the no-nonsense option — JBL QuantumSOUND audio tuning, a Voice-Focus mic with inline controls and a secure Twistlock in-ear fit, all in a compact wired form you can carry anywhere. Plug into any 3.5mm jack and you’re gaming. No charging. No latency. No compromise.

Sound
JBL QuantumSOUND Signature
QuantumSOUND is JBL’s gaming-specific tuning — built for directional clarity, environmental audio accuracy and voice intelligibility rather than the bass-boosted curve of consumer earphones. In competitive play, hearing footsteps, reloads and positional audio accurately is a genuine advantage. The Quantum 50 delivers this in a portable in-ear form.

Mic
Voice-Focus Inline Mic
Positioned on the inline controller close to the mouth, the Voice-Focus mic keeps your voice pickup clear and consistent. Separate volume slider and instant mic mute mean you can stay in full control mid-game without touching your device. A slider-based volume control also works on Windows where button-based controls on other earphones often don’t.

Fit
Twistlock — Stays Put
Twistlock twists the earphone into a locked position in the ear canal, preventing it from shifting during head movement, long sessions or rapid gameplay. Three silicone tip sizes (S, M, L) and L/R enhancers let you dial in the fit for your ear shape. Once in, it stays there.

Great choice if you…
✔ Want JBL gaming audio in a compact in-ear form

✔ Play on PC, PS4/5, Xbox, Nintendo Switch or mobile

✔ Need a mic for team play without wearing a full headset

✔ Want zero-latency wired audio — no battery, no pairing

✔ Prefer an understated black colourway for any setup

Consider something else if…
✖ You prefer over-ear headsets for deeper isolation

✖ You need virtual surround sound processing

✖ You want wireless freedom
