Best IEMs for CS2 in 2026: 4 picks, and what pros really wear

Why IEMs dominate competitive CS2 & tactical gaming

In modern tactical shooters like Counter-Strike 2, directional audio precision wins rounds. Hearing the exact material an opponent is walking on — whether it is the metallic clatter in Mirage vent or sandy shuffling outside B on Dust II — gives you the split-second needed to pre-fire.

In-Ear Monitors vs Over-Ear Headsets

• Passive Noise Isolation: IEM silicone or memory foam tips seal the ear canal directly, blocking ambient PC fans, keyboard clicks, and room noise better than most closed-back gaming headsets.
• Micro-Detail & Driver Speed: Balanced armature and stiff composite dynamic drivers react faster than large headphone diaphragms, giving rapid auditory cues (reloads, pin pulls, scope clicks) razor-sharp clarity.
• Zero Head Fatigue: At less than 10 grams per earpiece, IEMs eliminate headband pressure and ear cup heat during marathon Premier and FACEIT grinding.

Footstep frequency breakdown: How to tune your CS2 audio

In CS2, different surface footstep sounds live in specific frequency ranges:

• Low-End Thud (80 Hz – 250 Hz): The physical weight of jumping and landing. Excessive bass in cheap headsets bloats this range and masks teammate footsteps.
• Surface Texture (1 kHz – 3 kHz): The distinctive scrape of boots on sand (Anubis/Dust II), wood (Inferno banana/apartments), and concrete.
• Pinpoint Metallic Clicks (4 kHz – 8 kHz): Ladder climbs, bomb defusal pin clicks, weapon scoping, and metallic vent steps.

Our top pick, the Truthear x Crinacle Zero: RED, separates the subwoofer band (<200 Hz) using a dedicated crossover, ensuring grenade explosions never drown out subtle flanking footsteps.

Do CS2 pros actually use IEMs? The honest answer

This is the question behind most searches that land here, and it deserves a straight answer rather than a marketing one.

At LAN, yes — because they have no choice. Tournament rules require players to wear large soundproof ear defenders over their ears, to block crowd noise and prevent any chance of hearing information from outside the server. Those defenders go over something, and a bulky over-ear headset does not fit underneath. IEMs do. That is the real reason the LAN stage is full of in-ears.

At home, mostly no. We maintain a database of pro settings and gear, and every player in it currently runs an over-ear headset:

So if you came here expecting “the pros use IEMs, therefore you should”, the honest version is narrower: pros use IEMs when a headset physically cannot go under ear defenders. Outside that constraint, most of them go back to over-ear.

That does not make IEMs a bad choice for you — the arguments below stand on their own merits. It just means the argument from authority does not hold, and anyone selling it to you is not looking at the same data.

The thing that actually decides your isolation: the seal

Driver counts sell IEMs. The seal is what makes them work.

An in-ear monitor isolates by closing your ear canal. If the tip does not seal, you lose the low end first — and with it, the contrast that makes a footstep stand out against room noise. A €200 set with a bad seal is beaten by a €40 set with a good one, every time.

Three practical consequences:

Try every tip in the box. Most IEMs ship with three or four sizes, and a large number of people need different sizes in each ear. It feels wrong; it is completely normal.

Foam beats silicone for isolation, silicone beats foam for treble. Memory foam tips expand into the canal and block more ambient noise, which helps in a noisy room or a LAN hall. They also soften the 4–8 kHz band slightly, which is exactly where metallic footstep cues live. Pick according to your room, not according to a review.

If you have to push hard to get a seal, the tip is too small. A seal that needs pressure will break the moment you move your jaw — talking on comms, for instance. The right size seals with almost no force.

Which of the four, for whom

All four are under the price of a mid-range gaming headset, and all four beat a cheap headset on isolation. The difference between them is tuning, not quality.

You want the safest first IEM. Take the Truthear x Crinacle Zero: RED. Its dual-dynamic design puts a dedicated driver on the sub-bass, so explosions stay in their own lane instead of smearing over footsteps. It is the least likely of the four to disappoint, and the one to pick if you are not going to spend an evening comparing.

You want to tune it yourself. Take the Linsoul KZ ZS10 Pro 2. Its hardware switches let you lift or cut bands physically rather than through software, so you can flatten the low end for competitive play and put it back for music without touching an equaliser.

You want the smallest, lightest, cheapest way in. Take the Moondrop CHU 2. It is the one to buy if you are unsure whether in-ears suit you at all — the cost of finding out is minimal.

You also listen to music on them. Take the Kiwi Ears Quartet. Its hybrid array is the most even of the four across the whole range, which is worth more outside the game than inside it.

What to pair them with

IEMs have no microphone, which is the one practical thing they cost you.

A standalone USB desktop microphone on a boom arm is the usual answer, and it is a genuine upgrade over any headset boom mic. The cheaper route is an aftermarket 2-pin cable with an inline mic, which costs very little and keeps everything on one cable.

You do not need a DAC or an amplifier. All four of these sit under 32 ohms with high sensitivity: a motherboard jack or a USB-C dongle drives them to painful volumes. Spend the money on tips instead.
