• LEFXMOPHY Mic Replacement — biggest strength: It is a direct plug-and-play 2.5mm detachable boom mic built specifically for JBL Quantum 100/350-family headsets, so you keep the headphones you already own.
• LEFXMOPHY Mic Replacement — biggest trade-off: It is a microphone part only. No earcups, no cable, no drivers — if your headset's audio side is dead, this fixes nothing.
• JotVira Ear Monitor Headphones — biggest strength: A complete 10mm dynamic-driver IEM with a detachable 4N OFC 2-pin cable, passive noise isolation and a full accessory kit out of the box.
• JotVira Ear Monitor Headphones — biggest trade-off: There is no microphone at all, so it cannot serve as a headset for voice chat or calls on its own.
• Who each pick is for: LEFXMOPHY for JBL Quantum owners patching a broken mic; JotVira for anyone who wants a mic-free wired IEM for listening and gaming audio.
This is a spare part, and it's honest about that. LEFXMOPHY makes a 2.5mm TR plug boom microphone designed to slot into JBL Quantum 100, 350, 100P, 100X and 360P gaming headsets. If your original mic snapped, got lost in a move, or the foam disintegrated, this replaces it without forcing you to buy a whole new headset. Plug and play, corded, no battery to charge.
The physical design matters here. You get a 5-inch (15 cm) steel flexible hose that bends 360 degrees, so you can position the capsule near your mouth and keep it there. The element is an omnidirectional condenser with a foam cover, and LEFXMOPHY pairs it with a silver-plated 2.5mm TR plug and describes noise cancellation with enhanced voice clarity. In practice, that combination is aimed at one job: putting your voice into a game chat or call clearly enough to be understood.
Buy it if you already own a compatible JBL Quantum headset and only the mic side is broken. It's the cheapest way to get back to a working headset, and the bendable steel boom is a genuinely useful detail since you can angle it exactly where you want.
JotVira Ear Monitor Headphones: Who It's For
The JotVira JV01 is the opposite kind of product: a complete pair of wired in-ear monitors, and deliberately mic-free. Inside each side sits a 10mm dynamic driver running a dual magnetic circuit, with an impedance of 16 ohm, sensitivity of 105 dB and a frequency range of 20 Hz to 20,000 Hz. That low impedance is the practical headline — it means ordinary phones, handhelds and controllers can drive these without a separate amp.
JotVira's pitch is clarity and separation. Each driver gets an independent sound channel, which the brand says keeps the sound undistorted and lets you pick out instrument detail across the range, from deep lows to sparkling highs. You also get an ergonomic semi-in-ear shell in ABS, aluminum and TPE, weighing 15.88 g total, with around 90 percent ambient noise blocked passively. No batteries, no charging, no ANC circuitry — just a seal and a decent fit doing the work.
The cable is a real selling point. It's 4N OFC wire with a detachable 2-pin connector and a 3.5mm plug, so it works with Android phones, Windows phones, MP3/MP4 players and speakers, and you can swap in other Hi-Fi cables later. The package includes a dust-proof pouch, three pairs of ear tips in S, M and L, left/right indicators on both the buds and cable, and a user manual. Note the details that matter for expectations: no warranty is listed, the target age range is adult, and the design is explicitly without a mic.
Buy it if you want an inexpensive entry into IEM-style listening — music, mobile gaming audio, or just a comfortable wired pair that isolates noise on a commute. The included tip sizes and detachable cable make it a reasonable gift too, which is clearly part of JotVira's intent.
Side-by-Side: Which Should You Choose?
• Best for replacing a broken JBL Quantum mic → LEFXMOPHY Mic Replacement. It's the only one of the two that is a microphone.
• Best for a complete listening solution → JotVira Ear Monitor Headphones. Drivers, cable, tips and pouch are all in the box.
• Best for voice chat and calls → LEFXMOPHY Mic Replacement, provided you own a compatible JBL Quantum headset to plug it into.
• Best for music and game audio quality → JotVira Ear Monitor Headphones. A 10mm dual-magnetic dynamic driver with a 20 Hz–20 kHz range is built for fidelity, not for talking.
• Best for noise control → JotVira Ear Monitor Headphones. Passive isolation of roughly 90 percent of ambient noise versus a mic with a foam cover.
• Best for cable flexibility → JotVira Ear Monitor Headphones. The detachable 2-pin 4N OFC cable can be swapped; the LEFXMOPHY mic is wired and fixed to its 2.5mm plug.
• Best for fit adjustment → LEFXMOPHY Mic Replacement. The 5-inch steel hose bends 360 degrees so you can aim the capsule precisely.
• Best for plug-and-play simplicity → LEFXMOPHY Mic Replacement, if the headset is compatible; otherwise JotVira's 3.5mm jack works with virtually any audio device.
These two barely compete — they solve different problems, and that's the honest answer. In my opinion, if you own a JBL Quantum 100/350/100P/100X/360P and the mic is the broken part, buy the LEFXMOPHY Mic Replacement. It's a targeted fix that keeps a headset you already like in service, and the bendable boom is well thought out. If instead you're starting fresh and want wired in-ear sound for music and gaming audio, I'd buy the JotVira Ear Monitor Headphones and add a separate mic if you ever need to talk. Only one of these makes noise; the other makes you heard.
FAQ
are studio headphones better than gaming headsets
what headphones do pro gamers use
There's no single answer, and it changes by game and by player. What the data here shows is the two common approaches: a headset with an integrated boom mic (the JBL Quantum 100/350 family, which the LEFXMOPHY mic is built for), or in-ear monitors like the JotVira JV01 with a detachable cable and no mic, paired with a separate microphone. Both are wired, low-latency setups.
do all headphones have mics
No. The JotVira Ear Monitor Headphones are explicitly sold without a mic — the title says so, and the design has no microphone at all. The LEFXMOPHY Mic Replacement is the opposite case: it is a microphone, a 2.5mm detachable boom for specific JBL Quantum headsets. So mics are a feature you check for, not a default.
can studio headphones be used for gaming
Yes. Wired in-ear monitors like the JotVira JV01 plug into a 3.5mm jack and its 16 ohm impedance means controllers, handhelds and phones can drive it directly. The catch is communication: with no mic, you'd need a separate microphone for team chat. Sound-wise, the 10mm dynamic driver and passive isolation around 90 percent make it a workable gaming audio option.
