(And Why Earbuds Can Be Surprisingly More Accurate)
It All Starts in the Game
When people talk about spatial audio in games, it’s easy to jump straight to the gear: gaming headsets, surround sound systems, virtual 7.1 software. But before any of that can matter, the game itself has to build the soundscape from the ground up.
Everything starts with the audio rendered in-game, and technology-wise… Honestly we’ve already peaked more than 20 years ago!
How 3D Space Transforms Into 3D Sound
Modern games don’t just play sounds in stereo, or left or right. And by stereo, we mean the intro to songs like the Red Hot Chili Peppers’ Snow (Hey Oh), or from Queen’s Bohemian Rhapsody where it’s either left or right, or somewhere in the middle of that.
Modern games are actually able to place sounds inside a 3D space – meaning, left, right, in front or back, above or below, and everything in-between including distance. Every footstep, gunshot, or environmental effect is assigned a position relative to your character and the resulting sound will reflect that.
The game engine tracks where that sound comes from, how far away it is, and how the environment affects it. Walls can block or muffle sound, open spaces like hallways can create reflections or echoes, and distance changes volume and detail and even what you’ll eventually hear; standing next to a sniper can give you the muzzle firing, while being fired upon by that sniper from very far away can just give you a bullet hiss that’s gonna rattle you for a second.
From there, the game uses spatial processing to translate that 3D information into something your audio hardware can reproduce. This is often done using techniques like panning, distance attenuation, and head-related transfer functions (HRTF), which simulate how sound reaches your ears from different directions. The end goal of all of that is actually this simple: to trick your brain into perceiving direction, distance, and space using just two ears.
How that information gets relayed unto you depends heavily on your audio setup.
Speaker Setups: Using Real Space & Real Limitations
In a traditional room setup where you use stereo speakers or a full surround sound system, spatial audio is created physically through the strategic placement of the speakers. Multiple speakers are (ideally) placed around you, and each one responsible for a specific channel. A sound behind you is played through rear speakers. Something to your left comes from the left speaker. In theory, this creates a very natural sense of space because sound is actually moving around you in the room.
But this setup comes with tradeoffs: room acoustics play a huge role in what you end up hearing. Sound reflects off walls, furniture, your action figure collection shelf, the person who happened to pass through, and the floors. These reflections can blur directional cues or make distances harder to judge so speaker placement matters a lot in this setup.
If the speakers aren’t positioned correctly or if you’re not sitting in the ideal spot, spatial accuracy starts to break down. What should sound like it’s directly behind you might feel slightly off to the side. Not that crucial when you’re watching a movie, but definitely puts you at a disadvantage if you’re trying to spot enemies.
All in all, speaker-based spatial audio depends less on the system, and more on the room itself which makes good spatial audio setups like this a bit on the expensive side. This is why most gamers instead go for…
Personal Audio: Simulating 3D Space Inside Your Head
Spatial audio in headphones and earbuds works very differently. Instead of relying on physical space, they simulate it directly inside your ears through science that can essentially be the same as magic. Because the sound goes straight into each ear without interacting with a room, there are no reflections or environmental variables to deal with. This creates a more controlled and consistent listening environment.
Spatial audio in headphones and earbuds relies heavily on how well the device can reproduce subtle differences between the left and right channels either based on algorithms like how Dolby Atmos does it, or through the game’s engine. Tiny variations in timing, volume, and frequency help your brain determine direction and when done right, this can create a convincing and highly immersive sense of space even without multiple physical speakers.
Good headphones or earbuds can make even a Steam Deck or your phone feel like you’re running VR by recreating a virtual world around you through sound. This is why sound imaging matters more in gaming.
Accurate Imaging Matters More Than You Think
Imaging refers to how precisely an audio device can place sounds within that virtual space. Strong imaging means you can clearly tell whether something is slightly left, far right, above, or behind you – and how far (this is the most important bit). Weak imaging, on the other hand, makes everything feel vague or clustered; and worse, it can give you false directions outright!
Interestingly, well-designed earbuds can sometimes outperform over-ear headphones in this area. Because earbuds sit closer to the ear canal and create a better seal that isolates that cavity from the outside much better than over-ear headphones can, they can deliver more precise channel separation. This means that there’s less variation in how sound reaches your ears compared to larger headphones, where factors like ear shape, cup size, positioning, and even outside noise coming in can alter the presentation, and mess with the accuracy.
This doesn’t mean, however, that all earbuds are better by default. Tuning, driver quality, and overall design still matter. Audiophile IEMs have been gaining a lot of traction in the gaming community thanks to a) TikTok influencers spamming their affiliate links to make bank (no judgement from us here!), and b) being leagues better than most earbuds that most people have used before.
IEMs ARE a huge step up from the giveaway that we’re all used to that used to come with your iPhone and that Apple’s currently selling separately, but I digress. But they’re tuned for listening to music first, and then watching shows or movies with and not for gaming. Gaming requires a specific tuning profile that highlights some frequency ranges in the mids and highs more, while dialing down a bit of the bass so those details highlighted don’t get masked.
But when done right, especially when you use gaming earbuds for gaming and audiophile IEMs for music and movies/shows, earbuds can offer very sharp and much more reliable positional cues than over-ear headphones can give, which is exactly what spatial audio in games is trying to deliver. And yes, most movies on streaming already come with surround sound audio tracks so it will make your investment in good earbuds a lot more worth it.
Conclusion?
At the end of the day, spatial audio starts in the game engine, but it lives or dies in how accurately your setup can reproduce it. Speakers try to build that space around you. Headphones and earbuds simulate it directly. And for many players, that controlled, consistent delivery is what makes personal audio such a strong choice for gaming.
Thankfully, both big gaming audio equipment companies, and smaller IEM manufacturers, have started making gaming-focused earbuds and IEMs. And if you want to check out our current recommendations for that (gaming IEMs list coming out soon!) you can check it out here.
