These two products get lumped together because both are "add a boom mic to a headset" fixes. That's where the similarity ends. One replaces a broken part on a specific wired HyperX model. The other converts a pair of wireless Bose noise-canceling headphones into something you can talk into. If you're building a streaming setup and you're torn between them, the deciding question is simple: which headphones do you already own?
• MICMXMO's biggest strength: it restores the exact mic your pre-2021 wired HyperX Cloud / Cloud II / Cloud Core / Cloud X headset shipped with — omnidirectional capsule, built-in noise cancellation, 360-degree bendable boom, plug-and-play with no drivers or batteries.
• MICMXMO's biggest trade-off: compatibility is extremely narrow. It only fits the Pre-2021 First Version Wired models with a "Square Jack Slot," and it will not work with newer or wireless versions of those headsets.
• Zosvoses QC35's biggest strength: it upgrades Bose QC35 / QC35 II headphones into a gaming and streaming headset with a cardioid boom mic, an inline one-touch mute switch, and a detachable 1.2 m cable.
• Zosvoses QC35's biggest trade-off: it's a cable-and-mic accessory, not a headset. It's useless unless you already own QC35 or QC35 II headphones, and it does nothing for HyperX owners.
• Buy MICMXMO if you own a pre-2021 wired HyperX Cloud-series headset whose mic has died or gone scratchy and you want the cheapest, simplest path back to clear comms.
• Buy Zosvoses QC35 if you own Bose QC35 or QC35 II headphones and want to use their noise cancellation for gaming, Zoom calls, or streaming without buying a second headset.
This is a repair part, and it's honest about that. The MICMXMO mic is a 3.5 mm plug-in boom microphone built specifically for the Pre-2021 First Version Wired Kingston HyperX Cloud 2 II — and the listing also names the earlier Cloud, Cloud Core, and Cloud X. The critical detail is the connector shape. If your headset's mic socket is a "Square Jack Slot," this fits. If it's round, it doesn't. There are two generations of these HyperX headsets and they take two different microphones, so check the slot before you buy.
What you get for the money is a complete, self-contained mic. The capsule is omnidirectional with built-in noise cancellation, a rated sensitivity of 32 dB, 50 ohm impedance, and a 75 dB signal-to-noise ratio. The boom bends a full 360 degrees and holds its position, so you can park it near your mouth and leave it there. The 3.5 mm plug is gold-plated, the housing is ABS plastic with an anti-oxidation copper boom, and the whole thing weighs about 10 grams. There's a foam windscreen in the box and nothing else — no headphones, no adapters, no batteries, no drivers.
For gaming and streaming, that spec sheet tells a coherent story: plug it in, bend it where you want it, talk. The omnidirectional pattern picks up your voice from any angle, which is forgiving if you move around while you play. The foam cover knocks down plosives and breath noise. The 17 cm cable is deliberately short — long enough to reach your mouth, short enough not to snag on your desk.
Who should buy it: anyone with a pre-2021 wired HyperX Cloud-series headset and a dead, crackly, or missing mic who wants to keep using the headset they already like. Who should skip it: owners of newer HyperX models, wireless Cloud headsets, or any other brand. It's also not a mic upgrade in the audiophile sense — it's a like-for-like factory replacement, and it's sold as a cost-effective alternative to OEM parts, not a studio mic. There's a one-year manufacturer warranty and a stated 24-hour customer-service response window if something's off.
The Zosvoses QC35 is a different animal entirely. It's a boom microphone cable designed to slot into Bose QuietComfort 35 and QuietComfort 35 II headphones, converting them into a communication headset. If you already own QC35s — maybe you bought them for flights or commuting — this lets you use that same pair for gaming and streaming instead of buying a dedicated headset.
The build is where the spec sheet earns its keep for streaming. The connectors are 24K gold-plated for oxidation and corrosion resistance, and the cable uses a high-purity oxygen-free copper core to cut resistance and keep the signal clean. The outer jacket is reinforced PVC, described as abrasion-resistant and tangle-free, and the connector has SR stress-relief rated to survive over 20,000 bends and pulls. For a cable you'll plug and unplug every day, that's the number that matters most.
The mic itself is cardioid — directional, aimed forward — with a high-density anti-pop foam cover that filters plosives and ambient noise. That's a meaningfully different approach from the omnidirectional capsule on the MICMXMO. A cardioid pattern rejects sound from behind and to the sides, which is exactly what you want if your mechanical keyboard, PC fans, or a nearby speaker are competing with your voice. The boom bends freely and locks where you put it. There's also an inline mute switch on the remote, which is the single most useful feature on this list for streamers: one touch kills your mic mid-sentence without touching software.
Who should buy it: QC35 or QC35 II owners who want one pair of headphones to do double duty — noise-canceling for travel, boom-mic comms for gaming and Zoom. Who should skip it: anyone who doesn't own QC35 or QC35 II headphones. Without those, this is just a cable with nowhere to go.
Side-by-Side: Which Should You Choose?
• Already own pre-2021 wired HyperX Cloud / Cloud II / Cloud Core / Cloud X → MICMXMO Microphone Replacement. It's the only one of the two that fits.
• Already own Bose QC35 or QC35 II → Zosvoses QC35. Same logic in reverse — this is the one built for your headphones.
• Best for noisy rooms and keyboards → Zosvoses QC35. A cardioid pickup pattern with an anti-pop foam cover rejects off-axis noise better than an omnidirectional capsule.
• Best for quick, hands-free mic control while streaming → Zosvoses QC35. The inline one-touch mute switch has no equivalent on the MICMXMO.
• Best for cable longevity under daily plugging → Zosvoses QC35. Reinforced PVC jacket plus SR stress-relief rated for 20,000+ bends and pulls.
• Best for a pure replacement with zero setup → MICMXMO Microphone Replacement. No drivers, no batteries, no pairing — plug the 3.5 mm jack in and you're done.
• Best for flexibility to reposition the mic → MICMXMO Microphone Replacement. The boom bends a full 360 degrees and holds, with a short 17 cm cable that stays out of the way.
• Best for travel headphones that also game → Zosvoses QC35. You keep the QC35's noise cancellation and add comms, instead of carrying two headsets.
• Best if you're on a strict budget → check the current price on Amazon for both. They're different categories of product, and the numbers move.
My Verdict
Only the MICMXMO Microphone Replacement, and only if yours is the Pre-2021 First Version Wired model with a "Square Jack Slot." Newer and wireless Cloud versions take a different microphone, and this one won't fit them.
No. It's designed for Bose QuietComfort 35 and QC35 II specifically, using a 2.5 mm connection on the headphone side. If you don't own one of those two models, it isn't the right accessory for you.
The Zosvoses QC35 has the edge on paper. Its cardioid pickup pattern focuses on the sound in front of it, and the anti-pop foam cover plus the inline mute switch make it easier to keep your stream clean. The MICMXMO is omnidirectional, which is more forgiving of mic position but picks up more of the room.
They sit in different categories — one is a replacement part, the other is a headset-conversion cable — so "value" depends entirely on what you already own. Check the current price on Amazon for each before deciding, since the numbers change over time.
