KZ ZS10 Pro 2 for Warzone & Competitive FPS: The Complete Setup

If you've landed here, you already suspect what a lot of Warzone players figure out eventually: your $150 gaming headset is losing gunfights for you. The KZ ZS10 Pro 2 keeps coming up in that conversation, and it deserves to — but only if you set it up correctly. Out of the box, with the wrong switch positions and the wrong tips, it's a fun music IEM. Configured properly, it's a locating tool. Here's the difference.

What's actually inside

The ZS10 Pro 2 runs five drivers per side: a 10mm dynamic driver handling lows through mids, plus dual 31736 balanced armature arrays — four BAs total — split across highs and ultra-highs, tied together by a three-way electronic crossover. That BA array is the part that matters for competitive play. Balanced armatures are fast and detailed in exactly the frequency range where footsteps, reloads, plate swaps, and directional cues live.

It also has four tuning switches, and this is where most people leave performance on the table.

The switch settings that matter

Here's the crucial detail: the ZS10 Pro 2's switches almost exclusively adjust the bass region — roughly everything below 500–600Hz — in steps of about 2–3dB each. They barely touch the treble at all.

That makes the competitive setup obvious once you understand the principle. Bass energy masks quieter high-frequency information — a loud explosion or a heavy low-end shelf will bury the footstep you needed to hear. It's a documented psychoacoustic effect, and we cover the mechanism in how loudness shapes what you hear.

For competitive play: switches down / off. Minimum bass. This strips low-end weight out of the signature and leaves the upper mids and treble — where the BAs live — unmasked and forward. Explosions become less cinematic. Footsteps become obvious. That's the trade you want ranked.

For campaign, immersion, or music: switches up. Add the bass back. Same IEM, completely different experience. This is the modularity argument in miniature — one purchase, two tools.

Seal is not optional

Stereo imaging collapses without a proper seal. A leaky fit doesn't just cost you bass — it destroys the left-right and front-back cues your brain uses to build a map of the lobby. If you take one thing from this guide, take this: fit matters more than settings.

Foam tips are the competitive choice. They isolate better than silicone, which means less ambient room noise competing with game audio, and they seal more completely. Our foam tip fit guide covers sizing — note the ZS10 series runs a wider nozzle than most KZ models, so check before ordering. Then get the insertion technique right using the fit guide.

Comms: you need a mic

The ZS10 Pro 2 uses standard 0.78mm 2-pin connectors, so adding a microphone doesn't mean buying a different IEM — it means buying a cable. A mic cable swaps straight in. This is the practical advantage of detachable-cable gear that gaming headsets can't match: you upgrade one component instead of replacing the whole thing.

Do you need a DAC?

For this set, on a phone or a modern console controller, generally no. The ZS10 Pro 2 is sensitive and easy to drive. Where a small USB-C dongle earns its place is if your PC's onboard audio hisses or your phone lacks a jack — a clean source floor matters more than raw power. Run through the DAC flowchart before spending.

Honest expectations

This is not a magic wallhack. What it gives you is a cleaner signal into your ears: unmasked treble detail, real isolation, and accurate stereo separation. Whether you convert that into wins is down to you. Some players also find the ZS10 Pro 2's treble a touch bright for long sessions — if that's you, one switch up softens the balance without giving up the detail entirely.

Alternatives worth knowing: the CCA CRA is the leaner, brighter, more single-mindedly competitive option, covered in our gaming IEM guide. The ZS10 Pro 2 is the pick if you want one set that plays ranked and sounds great with music.

Grab the ZS10 Pro 2, add foam tips and a mic cable, and set those switches down.
