If you want a plug-and-play over-ear gaming headset with a boom mic and a volume dial, choose SADES SA810; if you need compact in-ear monitors with a hybrid driver setup and a detachable cable, choose erjigo KZ ZST X. These two are barely in the same category. One is a classic wired gaming headset built around team chat and long sessions at a desk. The other is a musician's in-ear monitor that happens to work fine for gaming. I'll break down exactly where each one wins and where it falls short, based only on what the spec sheets actually say.
• SADES SA810 — biggest strength: a full over-ear package with a flexible noise-isolating boom mic, 50mm dynamic drivers, a volume control, and broad console/PC compatibility including PS4, Xbox One, Switch, PC, laptop, tablet, and phone.
• SADES SA810 — biggest trade-off: it's a bulky wired over-ear headset, and older Xbox One controllers still need a separate Microsoft adapter that isn't included.
• erjigo KZ ZST X — biggest strength: a hybrid 1BA+1DD driver design (10mm double-magnetic dynamic plus a 30095 balanced armature) with a detachable 0.75mm 2-pin cable, rated 12Ω and 20Hz–40kHz.
• erjigo KZ ZST X — biggest trade-off: it's an in-ear monitor with an optional mic, so there's no boom mic, no inline volume dial, and it depends on your device having a 3.5mm jack.
• Choose SADES SA810 if you want one headset for console and PC gaming with clear teammate chat out of the box.
• Choose erjigo KZ ZST X if you want detailed in-ear sound for music and gaming and you don't mind bringing your own mic solution.
The SA810 is the "one box, everything included" gaming headset. You get over-ear leather ear pads, an adjustable ergonomic headband, a flexible boom mic that positions right where you need it, and a wired 3.5mm connection with an inline volume control. The 50mm dynamic drivers are paired with what SADES describes as intelligent extreme bass enhancement — the pitch here is punchy game audio where gunshots and footsteps cut through, plus a mic that filters ambient noise so your squad hears you and not your room.
In my opinion, the real selling point is the flexibility of the mic. A long, bendable boom lets you tune the angle precisely, which matters more than people admit when you're in a party chat for hours. The over-ear leather pads and retractable band are designed for long wear, and SADES backs the headset with a 12-month warranty — a signal that this is built as a durable daily driver rather than a throwaway accessory.
Who should buy it: console and PC players who want voice chat handled by the headset itself, people who prefer the isolation of full over-ear cups, and anyone who wants a single cable and a volume dial within reach. Who should skip it: players who already own a standalone mic, anyone who wants something pocketable, and older Xbox One controller owners who'd rather not deal with a separate adapter. If you care most about price, check the current price on Amazon before deciding.
The KZ ZST X is a different philosophy entirely. It's an in-ear monitor built around a hybrid driver: a 10mm double-magnetic dynamic unit handling the low end and a 30095 balanced armature up front for high frequencies. The stated result is clean, fast, forceful sound with strong detail retrieval — the spec sheet calls out electroacoustic music, drum and bass, and instrumental material as natural fits. With a 12Ω impedance and a 20Hz–40kHz frequency range, it's an unusually wide band for an in-ear at this level.
The cable is a genuine feature, not an afterthought. It's a standard 100-core silver-plated wire with Kevlar fiber in the core to cut signal loss and distortion, and it's detachable via a 0.75mm 2-pin connector. That means you can swap cables, replace a damaged one, or upgrade the sound later — something the SA810 simply doesn't offer. The ergonomic cavity is shaped to the auricle, with soft silicone tips for noise isolation and an ear-hook design that keeps the buds locked in and the cable out of the way.
Who should buy it: music listeners who want detail and separation, gamers who already have a mic or use a desk mic, and anyone who values a replaceable cable and a compact kit. The package also includes a leatherette carrying case. Who should skip it: anyone who wants a boom mic built in, and anyone who dislikes in-ear fit or ear-hook cables. Note that the mic is listed as optional, so confirm which version you're getting.
• Best for built-in voice chat → SADES SA810. The flexible noise-isolating boom mic is part of the package; the KZ ZST X lists its mic as optional.
• Best for sound detail and separation → erjigo KZ ZST X. The 1BA+1DD hybrid setup and silver-plated Kevlar-core cable are aimed squarely at clarity and instrument separation.
• Best for console gaming → SADES SA810. It explicitly supports PS4, Xbox One, Switch, and more, with the caveat that older Xbox One controllers need an extra adapter.
• Best for portability → erjigo KZ ZST X. In-ear buds with a carrying case travel far more easily than a full over-ear headset.
• Best for long-wearing comfort at a desk → SADES SA810. Leather over-ear pads and an adjustable headband are built for marathon sessions.
• Best for upgradeability → erjigo KZ ZST X. The detachable 0.75mm 2-pin cable lets you swap or improve the cable over time.
• Best for bass-forward gaming punch → SADES SA810. The 50mm drivers with extreme bass enhancement are tuned for game impact.
• Best for music-first listening → erjigo KZ ZST X. The 20Hz–40kHz range and balanced armature high-frequency handling favor music detail.
If I had to pick one, I'd buy the SADES SA810 for a gaming-first setup. In my opinion, the all-in-one formula wins for most people: boom mic, volume control, over-ear comfort, and wide console compatibility without buying anything else — unless you own an older Xbox One controller. I'd choose the erjigo KZ ZST X instead if music listening comes first or you already have a separate mic, because its hybrid drivers and detachable cable are simply more flexible and more detailed. Different tools, different jobs — match the tool to your main use.
For gaming with voice chat, the SA810 is the easier pick because its boom mic, volume control, and over-ear design are ready out of the box. The KZ ZST X works well for game audio and detail, but you'll need your own mic since its mic is listed as optional.
Only for older Xbox One controllers. SADES notes that newer Xbox One controller models have a headphone jack, while older ones require a separate Microsoft adapter that isn't included. PS4, PC, Switch, laptop, tablet, and phone work over the 3.5mm jack.
Yes. It uses a detachable 0.75mm 2-pin connector, so you can swap or replace the cable. That's a real long-term advantage over the SA810's fixed cable if durability or future upgrades matter to you.
The KZ ZST X is the more music-focused design, with a 10mm double-magnetic dynamic driver plus a 30095 balanced armature, a 12Ω impedance, and a 20Hz–40kHz range tuned for detail and separation. The SA810 is voiced for game impact, so it's the better gaming tool.
