If you want to restore the boom mic on a JBL Quantum 100 or 350 gaming headset for a fraction of the cost of new cans, choose LEFXMOPHY Mic Replacement; if you need a complete wired open-ear headphone with a detachable mic and inline controls for calls, gaming, and everyday listening, choose QOEKUEY Open Ear Headphones.
• LEFXMOPHY Mic Replacement — biggest strength: A drop-in 2.5mm boom mic that brings a JBL Quantum 100/350 back to life with plug-and-play simplicity.
• LEFXMOPHY Mic Replacement — biggest trade-off: It's a mic only. No drivers, no cable, no headphones — and it works only with specific JBL Quantum models.
• QOEKUEY Open Ear Headphones — biggest strength: A full wired headphone package: 40mm dynamic drivers, open-ear comfort, detachable mic, and inline volume/playback controls.
• QOEKUEY Open Ear Headphones — biggest trade-off: Wired only, and the open-ear design means no isolation from a noisy room — it's the opposite of sealed gaming audio.
• Who LEFXMOPHY is for: Anyone whose JBL Quantum 100 or 350 mic is broken, lost, or crackling.
• Who QOEKUEY is for: Buyers who want one wired headset for calls, gaming chat, and long listening sessions without ear fatigue.
This is a repair part, not a headset. The LEFXMOPHY Mic Replacement is a 2.5mm detachable boom microphone built specifically for the JBL Quantum 100, 350, 100P, 100X, and 360P headsets. It uses a silver-plated 2.5mm TR plug, so it slots straight into the mic port your original boom came out of. No adapters, no software — plug and play.
What it does best is solve one very specific, very annoying problem. Condenser boom mics take a beating: they get bent, chewed by pets, yanked out mid-game, or just quietly stop working. The LEFXMOPHY replacement is a 5-inch (15cm) steel flexible hose that bends 360 degrees, so you can shape it toward your mouth the way you like. It's an omnidirectional condenser with a foam cover, and the listing calls out noise cancellation and enhanced voice clarity — silver plating on the plug is there for a cleaner signal connection. For team chat, Discord, and in-game comms, that's the whole job.
Who should buy it: someone who already owns a compatible JBL Quantum and only needs the mic back. It's a one-part fix, and it keeps a working headset out of the drawer.
QOEKUEY Open Ear Headphones: Who It's For
The QOEKUEY Open Ear Headphones are a complete wired headset in black, built around open-ear ear placement with a curved ergonomic shape. The idea: the earpieces rest against your ears rather than sealing over them, so air keeps moving and pressure stays low. QOEKUEY's own copy frames this around "optimal comfort during extended listening sessions," and that's exactly the pitch — marathon calls, all-day work, long gaming sessions where sealed cups start to feel like a clamp.
The audio hardware is real, not decorative: 40mm dynamic drivers, 32 ohm impedance, 20Hz–20kHz frequency range, and 102dB sensitivity. That combination is easy to drive — a phone, laptop, or console controller headphone jack handles it without a separate amp. Connectivity is a 3.5mm jack plus USB, so it covers smartphones, tablets, computers, and gaming consoles. There's also an inline control pod with push buttons for volume and playback, which means no diving into menus mid-call.
The detachable mic is the headline for gaming and calls. It's positioned as professional-grade for clear voice capture, and it pops off when you just want to listen. The cable is a braided "crystal" design meant to resist tangling and survive daily abuse, and the enclosure mixes braided cable, metal, and plastic. Noise control is passive — no active circuitry, just the natural effect of open-ear placement. QOEKUEY backs it with a one-year warranty.
Who should buy it: people who want one wired headset that does calls, gaming chat, and music, and who hate the sweaty sealed feeling of over-ear cups. Also good if you switch between a laptop, a phone, and a console, since the dual 3.5mm + USB connection covers all three.
Side-by-Side: Which Should You Choose?
• Best for fixing a broken JBL Quantum mic → LEFXMOPHY Mic Replacement. It's purpose-built for those exact models.
• Best for a complete headset out of the box → QOEKUEY Open Ear Headphones. Drivers, cable, mic, and controls all included.
• Best for long sessions without ear fatigue → QOEKUEY Open Ear Headphones. Open-ear placement avoids the clamping pressure of sealed cups.
• Best for gaming voice chat on a budget repair → LEFXMOPHY Mic Replacement. Omnidirectional condenser with a bendable 15cm boom and foam cover.
• Best for device flexibility → QOEKUEY Open Ear Headphones. 3.5mm plus USB covers phones, tablets, computers, and consoles.
• Best for quiet, focused listening → neither. Open-ear leaks sound in and out; the LEFXMOPHY part doesn't produce audio at all.
• Best for microphone adjustability → LEFXMOPHY Mic Replacement. 360-degree bendable steel hose lets you aim it precisely.
• Best as a one-time purchase that replaces nothing → QOEKUEY Open Ear Headphones. LEFXMOPHY only makes sense if you already own a compatible JBL Quantum.
If I had a JBL Quantum 100 or 350 with a dead or missing mic, I'd buy the LEFXMOPHY Mic Replacement without hesitating — it's the exact part, the plug matches, and it saves a working headset. But if I were starting from nothing and wanted one wired headset for calls, gaming, and music, I'd buy the QOEKUEY Open Ear Headphones. It's a complete product: 40mm drivers, detachable mic, inline controls, dual 3.5mm + USB, and a one-year warranty. In my opinion, the QOEKUEY is the better buy for most readers, because it stands alone. The LEFXMOPHY is the smarter buy for one narrow job — and only if you own the right JBL.
are studio headphones better than gaming headsets
Not universally. Studio headphones typically prioritize flat, accurate sound for mixing, while gaming headsets like the QOEKUEY pair 40mm dynamic drivers with a detachable mic and inline controls built for chat and convenience. Which is "better" depends on whether you need a microphone and controls or accuracy above all.
what headphones do pro gamers use
That varies widely — some use sealed over-ear headsets for isolation, others use open-back or open-ear designs for comfort during long sessions. The QOEKUEY's open-ear approach fits the comfort-first camp, with a detachable mic for comms and passive noise control rather than active isolation.
do all headphones have mics
No. Plenty of headphones ship without any microphone at all. The QOEKUEY Open Ear Headphones include a detachable mic, and the LEFXMOPHY Mic Replacement is a mic on its own — but it only works when plugged into a compatible JBL Quantum 100/350/100P/100X/360P headset.
can studio headphones be used for gaming
Yes, technically — any headphone with a 3.5mm connection can output game audio, and the QOEKUEY's 32 ohm impedance and 102dB sensitivity make it easy to drive from a controller or laptop. The catch is voice chat: without a mic you'd need a separate one, which is exactly the gap the detachable QOEKUEY mic fills.
