• LEFXMOPHY Mic Replacement — biggest strength: a silver-plated 2.5mm TR plug and an omnidirectional condenser capsule built specifically for JBL Quantum 100/350 family headsets, so it slots straight in with plug-and-play simplicity.
• LEFXMOPHY Mic Replacement — biggest trade-off: it only fits JBL Quantum models. If you own a Logitech G PRO X, this is not the mic for you.
• BTFO Replacement Microphone — biggest strength: gold-plated anti-oxidation contacts, an ABS housing with a PVC cable, and copper internals, plus two high-density foam covers in the box.
• BTFO Replacement Microphone — biggest trade-off: it is built for Logitech G PRO X and G PRO X2 headsets only, and its listed connection is a USB-style 3.5mm jack, so a JBL owner cannot use it.
• Who each pick is for: LEFXMOPHY is for JBL Quantum owners with a lost, broken or damaged boom mic; BTFO is for Logitech G PRO X / G PRO X2 owners in the same situation.
This is a single-purpose part, and that is its whole appeal. The LEFXMOPHY Mic Replacement exists to replace the detachable boom microphone on a JBL Quantum 100, 350, 100P, 100X or 360P headset. It is not a universal mic, and it does not pretend to be. If your Quantum's mic has gone missing, stopped transmitting, or been chewed by a pet, this is the piece that puts the headset back into service.
The design is straightforward. There is a 5 inch / 15 centimeter black steel hose that bends through 360 degrees, so you can shape it toward your mouth and leave it there. At the tip sits an omnidirectional condenser capsule wrapped in a foam cover. The connection is a silver-plated 2.5mm TR plug, which is the physical fit that matters most here. Because it is a corded part with no battery, there is nothing to charge and nothing to pair. You unplug the old mic, plug in this one, and you are done.
BTFO Replacement Microphone: Who It's For
The BTFO Replacement Microphone plays the same role for a different camp. It is designed for the Logitech G PRO X and G PRO X2 gaming headsets, and it is a detachable boom mic with a foam-covered tip. If your Logitech mic has been lost or has started cutting out, this is the direct path back to clear voice chat.
Where this one stands out is material spec. The housing is ABS, the cable is PVC, and the internal contacts are gold-plated to resist oxidation over time. That last detail matters more than it sounds. A headset mic plugs and unplugs constantly, and oxidation at the contact point is a common reason mics get scratchy or drop out. Copper components and a gold-plated interface are the kind of details I look for in a long-term replacement part, because the whole point is to not think about it again.
The 360-degree adjustment is a real convenience, and so is the ability to position the mic on the left or right side. Some headsets force the boom to one side; this one lets you choose. You also get two high-density foam covers rather than one, which helps with wind noise, plosives and breath sounds, and gives you a spare for when the first one gets grimy. At 30 grams it is light enough not to drag on the boom arm. The catch is the same as the other product in reverse: this is a Logitech-only part. JBL Quantum owners should not buy it, and the listed USB connectivity in the spec sheet is a signal that this is not a generic 2.5mm swap.
• Best for JBL Quantum 100 / 350 / 100P / 100X / 360P → LEFXMOPHY Mic Replacement. The 2.5mm TR plug and JBL-specific fit are the deciding factors.
• Best for Logitech G PRO X / G PRO X2 → BTFO Replacement Microphone. It is made for those two headsets and nothing else.
• Best for spare foam covers → BTFO Replacement Microphone. You get two high-density covers in the box instead of one.
• Best for left/right mic placement flexibility → BTFO Replacement Microphone. It can be positioned on either side, which matters if your setup puts your mic arm on the "wrong" side.
• Best for a simple plug-and-play JBL fix → LEFXMOPHY Mic Replacement. No battery, no pairing, corded power, straight swap.
• Best for a lightweight boom that will not sag → BTFO Replacement Microphone. At 30 grams it is light on the arm.
• Best for a bendable steel hose that holds its shape → LEFXMOPHY Mic Replacement. The 15cm steel flexible hose is designed to bend and stay put.
My Verdict
If you own a Logitech G PRO X or G PRO X2, I would buy the BTFO Replacement Microphone. The gold-plated contacts, the ABS and copper construction, the left-or-right positioning and the two foam covers make it the more thoughtfully specified replacement part of the two, and it is purpose-built for exactly those headsets. If you own a JBL Quantum, that reasoning flips instantly. The BTFO mic will not fit your headset at all, and the LEFXMOPHY Mic Replacement is the correct, no-drama fix. Match the part to the headset brand first, then think about anything else.
are studio headphones better than gaming headsets
Not universally, and it depends on what you need. Studio headphones are typically built for accurate, neutral audio monitoring and often ship without a microphone at all, while gaming headsets like the JBL Quantum and Logitech G PRO X lines are designed around a built-in boom mic for voice chat. If you need to talk to teammates, a gaming headset is the more practical choice. That is also why replacement mics like these two exist.
what headphones do pro gamers use
There is no single answer, and you should be skeptical of anyone who claims otherwise. Competitive players tend to favor headsets with clear positional audio and a reliable detachable mic, which is exactly the category the JBL Quantum and Logitech G PRO X families sit in. Sponsorship deals also shape what you see on stream, so what a pro wears is not always what a pro would buy. Judge the hardware on its own merits.
do all headphones have mics
No. Plenty of headphones, especially studio and audiophile models, have no microphone whatsoever. Gaming headsets almost always do, and many of them, including the JBL Quantum and Logitech G PRO X models covered here, use a detachable boom mic. That detachable design is convenient until the mic is lost or broken, which is the exact scenario both of these replacement parts are made to solve.
can studio headphones be used for gaming
Yes, they can, and plenty of people do it. Studio headphones often deliver accurate sound and comfortable long-session fit, which works well for games. The catch is voice chat: without a mic you would need a separate desktop or clip-on microphone. If you want one cable and one device, a gaming headset with a boom mic is simpler. If you already own studio headphones, a standalone mic is the cleaner path.
