These wired in-ear headphones utilise QuantumSOUND Signature audio to enhance competitive play across PC, console, and mobile devices. The integrated Voice-Focus inline microphone includes a dedicated mute button for clear communication during gaming sessions. Twistlock technology ensures a secure fit, while the 3.5mm connection provides immediate plug-and-play functionality without the need for charging.

The JBL Quantum 50 Wired Gaming Headset White is what JBL gaming audio looks like in an in-ear form — compact enough to carry anywhere, but tuned with the same QuantumSOUND Signature technology that powers the full Quantum range. Plug into any 3.5mm device and hear enemies before they see you. No battery. No lag. No pairing.

Sound
JBL QuantumSOUND Signature
JBL’s QuantumSOUND tuning is designed specifically for gaming — not flat reference audio or bass-heavy music tuning. The result is a soundscape where directional cues, footsteps, environmental audio and voice communication are all reproduced clearly. In competitive play, sound positioning genuinely matters, and the Quantum 50 delivers that in an in-ear form.

Mic
Voice-Focus Inline Mic
The microphone sits on the inline controller close to your mouth — positioned deliberately away from the earphones so it picks up your voice rather than cable noise. Separate volume slider and mic mute button on the controller let you adjust both without touching your device. Critical in team play where communication is as important as audio.

Fit
Twistlock In-Ear Technology
Twistlock is JBL’s twist-to-lock ear tip system — the earphone twists into the ear canal and locks in position, preventing it from working loose during extended sessions or rapid head movements. Includes three sizes of silicone ear tips (S, M, L) and L/R enhancers to help optimise the fit for your ear shape.
