How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a cheap, targeted fix for a broken or lost boom mic on a JBL Quantum headset, choose LEFXMOPHY Mic Replacement; if you need a full in-ear FPS audio setup with its own detachable cable, sound card and noise-cancelling mic array, choose Bawjog KZ Axas FPS.
• LEFXMOPHY's biggest strength: it's a plug-and-play 2.5mm detachable boom mic built specifically for JBL Quantum 100/350, 100P, 100X and 360P headsets — a direct replacement for a mic you've lost or snapped.
• LEFXMOPHY's biggest trade-off: it's a part, not a product. It only works with the listed JBL Quantum models, and it gives you no audio of its own beyond the mic itself.
• Bawjog KZ Axas FPS's biggest strength: a complete wired in-ear FPS system — 10–20kHz ultra-wideband drivers, a portable sound card with one-click presets, and a dual-silicon mic array with hardware AI noise cancellation.
• Bawjog KZ Axas FPS's biggest trade-off: this listing is the Without Mic variant, and it's an in-ear set, not a headset — so there's no boom arm and no over-ear cups.
• Get LEFXMOPHY if you already own a compatible JBL Quantum headset and just need the mic back.
• Get Bawjog KZ Axas FPS if you want to build a competitive FPS earphone setup from scratch.
This is a repair part, and it's honest about that. The LEFXMOPHY Mic Replacement is a 5-inch (15cm) 360-degree bendable steel boom with a condenser omnidirectional capsule and a foam cover, terminating in a silver-plated 2.5mm TR plug. The polarity is omnidirectional, meaning it picks up sound from all around the capsule rather than from one tight direction — normal for a headset boom, and paired here with noise cancellation and enhanced voice clarity. It's wired, corded, and draws no battery.
The compatibility list is the whole story: JBL Quantum 100, 350, 100P, 100X and 360P. If that's your headset and your mic died, this is the shortest path back to talking to your squad. You plug it in and go. The steel hose means you can bend it toward your mouth and it holds position, and the foam cuts down on breath and plosive noise. Enclosure materials are steel and foam, one mic per pack.
Who should skip it? Anyone who doesn't own one of those JBL Quantum models. Anyone wanting a full audio upgrade rather than a replacement. And anyone who wants an in-ear, esports-style tuning — this is a headset part, so it inherits whatever sound your JBL headset already delivers. If your headset is fine and only the mic is gone, though, that's exactly the problem it solves.
The KZ Axas is a very different animal: a wired in-ear monitor built for FPS games, sold here in the Without Mic configuration. The headline spec is the self-developed 10–20kHz ultra-wideband Hi-Fi gaming driver set, tuned to lift low-frequency footsteps and high-frequency gunshots so positional cues stay readable. KZ describes low distortion so gunfire stays impactful without being piercing — the kind of thing that matters over a four-hour session.
Then there's the portable sound card. It's a compact DAC that unlocks higher audio resolution and carries one-click audio presets, so you can flip between FPS-tuned profiles for different games and playstyles without digging through menus. That's a real convenience if you bounce between, say, a tactical shooter and a battle royale.
Electrically: 20Ω impedance, 107dB/mW sensitivity at 1kHz, 10–20000Hz frequency response range, 3.5mm/Type-C plug, 0.78mm pin type, over-the-ear wearing style, double parallel silver-plated wire at 120±5cm. KZ also flags a usage tip — because the sound card drives the high-sensitivity drivers hard, set system volume to 30% or lower before first use, then tune from there. Passive noise cancellation comes from the eartip seal. One-year manufacturer warranty.
Skip it if you want an over-ear headset with a boom mic, if you specifically need a mic included (this variant doesn't have one), or if you don't want to fiddle with volume and EQ presets. Buy it if you want an in-ear esports tool with its own cable and sound card.
Side-by-Side: Which Should You Choose?
• Best for fixing a broken JBL Quantum mic → LEFXMOPHY Mic Replacement. It's the only one of the two that's actually a replacement part for a headset you already own.
• Best for a complete setup from zero → Bawjog KZ Axas FPS. Earphones, cable, sound card and presets in one box.
• Best for voice chat on a headset you like → LEFXMOPHY. Omnidirectional condenser with foam, bendable 5-inch boom, 2.5mm TR plug.
• Best for on-the-go profile switching → Bawjog KZ Axas FPS. The one-click sound card presets are the differentiator here.
• Best for low-fuss, no-battery use → either. Both are wired and corded; neither needs charging.
• Best for long-session comfort with glasses or hats → Bawjog KZ Axas FPS. In-ear with over-ear cable routing avoids headband pressure.
• Best for someone who already owns an over-ear headset and wants to keep using it → LEFXMOPHY. Don't replace a working headset to fix a $0-problem mic.
• Check the current price on Amazon for both before deciding — the value math depends entirely on what you already own.
In my opinion, these two barely compete for the same buyer, so the honest answer is: buy the one that matches your situation. If you own a JBL Quantum 100, 350, 100P, 100X or 360P and your mic is dead or missing, I'd get the LEFXMOPHY Mic Replacement — it's the specific, correct part and it restores exactly what you lost.
If you're starting fresh or want to move to an in-ear FPS rig, I'd go Bawjog KZ Axas FPS — the ultra-wideband drivers, portable sound card and preset switching make it the more capable piece of kit. Just remember this listing is the Without Mic version, so pair it with a separate mic if you need comms.
FAQ
are studio headphones better than gaming headsets
what headphones do pro gamers use
There's no single answer, and it varies by title and region. What the KZ Axas data sheet shows is that it was engineered with KZ Acoustics Lab and Tianba Esports pros — an in-ear, over-ear-cable design with a separate sound card, which is a common esports form factor. Many pros favor in-ears for isolation and consistency on stage.
do all headphones have mics
No. Plenty of headphones and earphones ship without a microphone, and this listing is a good example: the Bawjog KZ Axas FPS here is the Without Mic variant despite the product line offering a dual-silicon mic array elsewhere. The LEFXMOPHY Mic Replacement, by contrast, is a microphone only — no speakers at all.
can studio headphones be used for gaming
Yes, technically — any wired headphone can play game audio. But you lose the gaming-specific tuning and often the mic. The LEFXMOPHY part only fits specific JBL Quantum headsets, and the KZ Axas pairs its own sound card and presets for that purpose. If you game and talk, plan for a mic separately.
