If you want a wired in-ear monitor that doubles as a gaming and music earphone with a detachable cable and a proper driver setup, choose Kinboofi KZ ZSN PRO; if you need a drop-in replacement boom mic for a Logitech G PRO gaming headset you already own, choose REEYEAR Replacement Game Mic. These two products solve completely different problems, which is why the "vs" in this comparison is really about matching a job to a part rather than picking a winner out of a pile.
• Kinboofi KZ ZSN PRO — biggest strength: a 1BA + 1DD hybrid driver setup (10mm dual magnetic dynamic driver plus a 30095 balanced armature) in a metal-and-resin shell with a detachable 2-pin style cable.
• Kinboofi KZ ZSN PRO — biggest trade-off: it's a wired 3.5mm in-ear monitor, and the inline control handles a single button only — volume control is not supported.
• REEYEAR Replacement Game Mic — biggest strength: a purpose-built, 360-degree bendable boom mic that's molded to Logitech G PRO headset dimensions, so it slots into an existing headset instead of replacing it.
• REEYEAR Replacement Game Mic — biggest trade-off: it only works with the Logitech G PRO X2, G PRO X wireless and G PRO wired headsets, and it won't function if you plug it straight into a VR headset.
• Who each pick is for: the KZ ZSN PRO X is for someone who wants one wired earphone for music, monitoring and gaming; the REEYEAR mic is for someone whose Logitech headset mic is broken, lost or worn out and who just wants the boom back.
The KZ ZSN PRO X is the upgrade path in the KZ ZSN PRO line, and the spec sheet shows where the effort went: drivers, cable material, shell and tuning. On paper the headline is the hybrid setup — a 10mm dual magnetic dynamic driver handling the low end paired with a 30095 balanced armature for the highs. That is a genuine two-driver design, not a single full-range driver pretending to be more. KZ says the tuning was done by a professional acoustic team, and the practical claim that matters to a buyer is a wider frequency response with fuller, clearer vocals. The 25 ohm impedance figure is also worth noting: low-impedance IEMs like this are easy to drive, so a phone, a laptop or a basic dongle will get usable volume out of them.
Who should buy it: musicians and performers who want an affordable in-ear monitor, gamers who prefer a wired IEM over a bulky over-ear headset, and anyone who listens to music on a wired connection and cares more about driver hardware than about wireless convenience. Who should skip it: anyone who needs volume buttons on the cable — the sheet is explicit that volume control is not supported, only the single control button. Also skip it if you want a built-in microphone on a boom; the "with mic" version here refers to an inline mic on the cable, not a positioning boom.
REEYEAR Replacement Game Mic: Who It's For
This one is a very narrow product, and that narrowness is its whole point. The REEYEAR Replacement Game Mic is a detachable boom microphone made to fit the Logitech G PRO X2, G PRO X wireless and G PRO wired gaming headsets. It is explicitly a replacement part: the listing says "mic only," and the headset is not included. If your Logitech boom mic has died, gone missing or started cutting out mid-match, this is the part that gets you back into voice chat without buying a whole new headset.
The construction details are more specific than you'd expect from a replacement part. It's described as 1:1 molded to the original Logitech headset's dimensions, with a soft boom, an ABS head, an anti-oxidation gold-plated copper connection, a stainless steel windscreen and a plop filter built into the neck. The mic is unidirectional and bends a full 360 degrees, which is what lets you position the capsule right at the corner of your mouth without fighting the headset. The 3.5mm AUX plug is gold-plated. A foam cover is included in the box.
Two compatibility notes in the sheet are worth taking seriously. First, the listing states that your headphone's G-Hub software should be properly connected to your PC when using the G PRO headset, which is a hint that this is a system where the headset, the software and the mic all need to line up. Second, and more bluntly, it says the mic will not work if you plug it directly into a VR headset — it requires the G-PRO VR headset. The listing also states plainly that it is not an OEM product, so treat it as a third-party replacement rather than a factory part.
Side-by-Side: Which Should You Choose?
• Best for listening to music → Kinboofi KZ ZSN PRO. Two drivers (1BA + 1DD), a metal-and-resin shell and a silver-plated copper cable — it's built as an earphone first.
• Best for fixing a broken headset → REEYEAR Replacement Game Mic. It's a direct replacement part for G PRO X2, G PRO X wireless and G PRO wired headsets, nothing more.
• Best for cable longevity → Kinboofi KZ ZSN PRO. The detachable cable means a failed wire doesn't kill the earphone.
• Best for voice chat clarity → REEYEAR Replacement Game Mic. Unidirectional, 360-degree bendable, with noise cancellation and a foam cover included.
• Best for low-impedance, easy-to-drive audio → Kinboofi KZ ZSN PRO. 25 ohm impedance is friendly to phones and laptops.
• Best for a specific ecosystem → REEYEAR Replacement Game Mic. It only makes sense inside the Logitech G PRO headset family.
• Best for musicians and monitoring → Kinboofi KZ ZSN PRO. The in-ear monitor framing and over-ear memory tube point squarely at stage and studio use.
• Best for a quick, low-hassle repair → REEYEAR Replacement Game Mic. No cable to route, no fit to figure out — it clicks into a headset you already own.
In my opinion, the Kinboofi KZ ZSN PRO is the better buy for most people, because it's a complete product: you get the earphone, the cable, the drivers and the controls in one purchase, and the detachable cable gives it a longer practical life. The REEYEAR mic is genuinely good at what it does, but it's a repair part with a narrow compatibility list — it only earns its place if you already own a Logitech G PRO headset and its boom has failed. If you need that specific fix, buy the REEYEAR. If you're starting from nothing, I'd go with the KZ ZSN PRO X. Either way, check the current price on Amazon before you commit, since that's the one number that decides whether a repair part is worth it versus a new headset.
FAQ
No. It's built for the Logitech G PRO X2, G PRO X wireless and G PRO wired gaming headsets. The listing also notes it won't work if you plug it directly into a VR headset — it needs the G-PRO VR headset.
The version described here is the "with mic" style, which means an inline mic on the cable with a single control button. It is not a boom mic and it does not offer volume control.
They're not competing on the same job. If you need a working headset mic, the REEYEAR is the cheaper path than replacing a whole headset. If you need an earphone for music, monitoring or gaming audio, the KZ ZSN PRO X gives you more product for the money. Check current prices on Amazon and decide based on which problem you actually have.
