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.

FAQ
Frequently asked
Why do pro CS2 players use IEMs instead of headsets?
At LAN tournaments, players must wear mandatory soundproof ear defenders over their ears. Underneath, they wear IEMs because they fit flush inside the ear canal. Online, pros continue using IEMs to avoid head fatigue and to get cleaner directional isolation without the clamp pressure of heavy over-ear headsets.
Are IEMs better than gaming headsets for hearing footsteps in CS2?
In most cases, yes. A proper in-ear seal creates superior passive acoustic isolation and brings the sound source closer to your eardrum. Hybrid and tuned dynamic IEMs deliver crisp, fast high-frequency response, making footsteps and defuse sounds distinct from low-frequency utility explosions.
What is the best IEM under €60 for CS2?
The Truthear x Crinacle Zero: RED (dual dynamic driver with dedicated subwoofer) and the Linsoul KZ ZS10 Pro 2 (hybrid 1DD + 4BA with hardware tuning switches) are the two highest-rated competitive IEMs under €60.
How do I communicate with teammates if IEMs don't have a microphone?
Most competitive players pair their IEMs with a standalone USB desktop microphone (such as a HyperX QuadCast or dynamic mic on a boom arm). Alternatively, you can swap the cable for an aftermarket 2-pin IEM cable that includes an inline microphone.
Do I need a dedicated DAC/AMP for competitive gaming IEMs?
Generally no. Competitive IEMs like the Truthear Zero: RED and KZ ZS10 Pro 2 have low impedance (under 32 ohms) and high sensitivity. Your motherboard's 3.5mm jack or a simple USB-C to 3.5mm dongle provides plenty of clean driving power.
