How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a bright, detail-forward in-ear monitor that doubles as a wired gaming earphone and a dependable tool for vlogging, choose Linsoul KZ ZS10; if you need maximum driver count, deeper noise isolation and a metal-shell build that disappears on your head during long sessions, choose KZ Zax.
• Linsoul KZ ZS10 — biggest strength: a 4BA+1DD hybrid setup (two 30095 highs, two 50060 mids, plus a 10mm second-gen Tesla double-magnetic dynamic driver) with a stainless steel faceplate and a detachable gold-plated 0.75mm 2-pin cable.
• Linsoul KZ ZS10 — biggest trade-off: it isolates up to 26dB, which is good but clearly less than the Zax, and the cavity is resin with a plastic enclosure, so it feels less "premium metal" in hand.
• KZ Zax — biggest strength: 16 sounding units across both sides (7BA+1DD per side) in a zinc alloy faceplate over a transparent cavity, with up to 36dB of noise blocking.
• KZ Zax — biggest trade-off: heavier and bulkier in feel (27 g), and with that many drivers it leans toward a more analytical, layered presentation rather than a simple, punchy one.
• Who each pick is for: the ZS10 is for the vlogger or gamer who wants bright, energetic sound and an easy, light fit; the Zax is for the listener or streamer who wants the most isolation and the most complex driver architecture.
The ZS10 Pro is the more approachable of the two. Its whole design story is about being lively and clear: a 5-driver hybrid with two balanced armatures dedicated to highs and two to mids, backed by a 10mm dynamic unit handling the low end. The result, based on the configuration, is a bright, transient, detail-forward signature rather than a bass-first one. The frequency range runs 7Hz to 40kHz with a 24-ohm impedance and 111dB sensitivity, which tells you it's easy to drive from a phone, a laptop or a camera's headphone jack.
Physically, this is a light, rounded in-ear with a 304 stainless steel faceplate and a resin cavity. It's molded around ear-canal data to sit like a custom piece, and the spec sheet calls out that it stays put during vigorous movement — a real plus if you're shooting handheld video, walking and talking, or gaming with a controller. It isolates up to 26dB, which is enough to tame a noisy room but not enough to fully erase a loud one.
Buy it if you want an energetic, wired in-ear monitor for vlogging, gaming, podcasts or music, and you like the idea of a detachable cable you can swap later. Skip it if your priority is maximum noise blocking or the most drivers for your money — the Zax wins on both of those counts. Also note the small caveat in the specs: since September 2021 the cable shipped can vary between four types, with only cosmetic differences, so don't be surprised by which one arrives.
The KZ Zax is the spec-sheet maximalist. It packs 16 sounding units across both sides — a double-magnetic composite dynamic driver for bass, two 30019 closed balanced armatures for vocal detail, a 50024 combination for the wide sound field, and a classic 30095 for high-frequency overtones. It splits the spectrum into four sub-bands (low, mid, high, ultra-high), which is exactly the kind of architecture that gives you a broad, layered, highly analytical presentation. Sensitivity is 113dB at 24 ohms, so it's also easy to drive, and it covers 10Hz to 40kHz.
The build is the other headline. The faceplate is zinc alloy and the cavity is transparent, so you can see the internal structure, and the metal resists oxidation so it keeps its look over time. The nozzle pipes sound directly into the ear canal for a physical seal rated up to 36dB of isolation — notably more than the ZS10. KZ also uses an over-the-ear hook design to keep the cable from being yanked out mid-session.
Buy it if you want serious isolation, a durable metal shell, and the most intricate driver setup here — ideal for long streaming or listening sessions where you want the outside world gone. Skip it if you prefer a simple, punchy, easygoing sound or you want the lightest possible fit; the 27 g package and its analytical tuning aren't for everyone.

In my opinion, the Linsoul KZ ZS10 is the one I'd buy for most people — especially if vlogging is the main job. It's lighter, it's easier to live with, its bright tuning flatters speech and gaming cues, and the detachable cable gives you room to grow. I'd only steer you to the KZ Zax if isolation and driver count are your top two priorities, because its 36dB blocking and 16-unit architecture are genuinely a step up for long, immersive sessions. Both are wired 3.5mm in-ears, so neither is a wireless bluetooth headset for vlogging — if you need true wireless, neither fits that brief. For a wired earphones-for-vlogging setup, I'd start with the ZS10. Check the current price on Amazon before you commit, since that's the deciding factor for a lot of buyers.
how to fit in ear headphones
Insert the nozzle so it angles into your ear canal, then rotate the body until it seals. The Zax spec sheet describes a 45° in-ear angle with a 270° turn and the cable routed behind the ear, which is the classic over-ear IEM method.
how to clean in ear headphones
Wipe the nozzle and silicone tips after each use and clear any wax from the sound bore with a dry brush or cloth. Both models use detachable 0.75mm 2-pin cables, so you can unplug the cable before cleaning the shells to avoid stressing the connector.
how to open in ear headphones
There's nothing to open on either model — both are sealed in-ear monitors. If you mean opening the package, the ZS10 ships in a rigid box while the Zax uses a flat free package, and both include ear tips and basic accessories.

If you mean how to wear them, the key is the seal: the Zax's nozzle creates a physical seal rated up to 36dB, and the ZS10 isolates up to 26dB, so a proper fit is what delivers both the bass and the quiet. Push gently until the sound fills in, and swap tip sizes if it feels loose.
