Footsteps win Rainbow Six Siege matches. Not aim, not reflexes, not even game sense on its own — sound. Ask any high-level Siege player and they will tell you the same thing: if you hear the enemy first, you already won half the fight. That is exactly why so many fans keep asking what headset does Jynxzi use, because the guy who exploded into one of Twitch’s biggest streamers built his entire reputation on hearing things other players miss. When he calls out a roamer through two floors of Clubhouse, people want to know what is strapped to his head.
Here is the thing though — the answer is only half the story. Jynxzi’s audio advantage does not come from one magic product you can add to a cart. It comes from a specific combination of headset, amplifier, in-game settings, and habits that stack on top of each other. In this guide, you will learn exactly which headset he runs, why he chose it over wireless options, how his MixAmp changes the sound, what his complete streaming setup looks like, how to dial in Siege audio settings the way pros do, and which cheaper alternatives give you 90% of the same performance. By the end, you will not just copy his gear — you will understand why it works.
The Headset Jynxzi Runs for Rainbow Six Siege
Let’s get straight to the point before diving into the details. Jynxzi uses the Astro A40 TR headset paired with the Astro MixAmp Pro TR, a wired open-back gaming headset and external amplifier combo that competitive shooter players have trusted for over a decade. The A40 TR is not the flashiest headset on the market, it does not have RGB lighting, and it definitely is not wireless — and that is exactly the point.
The Astro A40 TR has been a staple at professional esports events since the Xbox 360 era. Astro is owned by Logitech, which is why you will sometimes see people mix up his gear with Logitech’s G Pro X line. Both brands live under the same roof, and Jynxzi has been spotted with Logitech peripherals across his desk, so the confusion makes sense. Still, the A40 TR plus MixAmp Pro TR combination is the setup most consistently linked to his Siege gameplay.
One important note before you rush to buy: streamer setups change. Sponsorships shift, new models launch, and creators swap gear between streams without announcing it. Jynxzi has used more than one headset over the years, and he has been seen with different models depending on whether he is playing Siege, recording content, or just chatting. Treat this article as a breakdown of the setup he is best known for, and always double-check his current gear list or a recent stream if you want the absolute latest.
What matters more than the exact model number is the philosophy behind the choice. Jynxzi picks audio gear that prioritizes three things:
- Accurate positional sound over booming bass
- A wired connection with zero latency and zero battery anxiety
- Fine-grained control over the game-to-voice mix during live streams
Every piece of his audio chain serves one of those three goals. Once you understand that, picking your own headset gets a whole lot easier.
Inside the Astro A40 TR: What Makes It a Competitive Favorite
The A40 TR is what audio nerds call an open-back headset, at least in its default configuration. Open-back means the outer housing of each earcup has openings that let air and sound pass through. That design choice creates a wider, more natural soundstage — the sense that sounds exist in a real space around you rather than trapped inside your skull. For a game like Siege, where you constantly judge whether a footstep is above you, below you, or coming around a corner, that spatial accuracy is gold.

The mod kit is the real trick
Astro sells a separate Mod Kit that converts the A40 TR from open-back to closed-back. The kit swaps the speaker tags for sealed ones, replaces the cloth earcups with synthetic leather, and adds a foam voice-isolating microphone. Tournament players love this because arena environments are loud and chaotic. At home, most streamers stick with the stock open-back setup for the wider soundstage — unless they have a noisy room or a mechanical keyboard that sounds like a hailstorm.
The other underrated feature is comfort. The A40 TR uses a lightweight frame with wide, cloth-covered memory foam earcups that sit around your ears instead of pressing on them. Jynxzi regularly streams for six, eight, sometimes ten-plus hours. A headset that clamps too hard or traps heat becomes unbearable at hour four. The A40’s loose clamping force and breathable pads are a big reason it survives marathon sessions.
Now, the A40 is not perfect. The bass is fairly restrained compared to something like a HyperX Cloud II, and the open-back design leaks sound both ways — your roommate will hear your game, and you will hear their music. But for a competitive player who cares about hearing a rappel or a drone above everything else, those tradeoffs are worth it.
The MixAmp Pro TR: The Piece Most People Skip
Here is where a lot of players go wrong. They buy the A40 TR, plug it straight into their PC, and wonder why it does not sound like the streams they watch. The headset is only half the system. The MixAmp Pro TR is the other half, and honestly it might be the more important half.
The MixAmp is an external digital-to-analog converter and amplifier that sits on your desk. It takes the audio signal out of your PC or console over USB or optical cable, processes it, and drives the headset with far more clean power than a motherboard headphone jack can deliver. At 48 ohms, the A40 genuinely benefits from that extra headroom. Without an amp, the headset sounds thin and quiet at high volumes.
What the MixAmp actually does for you
- Dolby Audio surround processing — it converts stereo into a virtual 7.1 field that helps you separate sounds coming from different directions and elevations.
- Game-to-voice balance dial — a physical knob that lets you turn party chat down and game audio up mid-round, without alt-tabbing into Windows settings.
- EQ presets — four switchable equalizer profiles you can customize in Astro’s Command Center software. Most competitive players build a preset that cuts bass and boosts the mid-to-high frequencies where footsteps live.
- Daisy-chaining — multiple MixAmps can link together over optical, which is how LAN teams share a private voice channel at events.
- Clean volume control — a big physical dial beats fumbling with keyboard media keys during a clutch.
Think about a practical scenario. You are on Consulate defending in the garage. A single enemy is walking on the floor above you, and at the same time your teammate is screaming a callout in Discord. Without a MixAmp, that teammate’s voice buries the footstep, and you die to a vertical play. With the MixAmp, you flick the balance dial two clicks toward game audio, hear the wood creak, pre-fire the ceiling, and get the kill. That is the entire value proposition in one moment.
The EQ preset is where the real customization happens. Many Siege players build a profile that rolls off frequencies below about 200Hz — explosions, breaching charges, and gunfire rumble — while lifting the 2kHz to 6kHz range where footsteps, gadget beeps, and reloads sit. It makes the game sound less cinematic and more like a radar. That is a trade competitive players happily make.
Why Jynxzi Sticks With Wired Audio Instead of Wireless
Wireless headsets have gotten genuinely great. Low-latency 2.4GHz dongles have mostly solved the delay problem, and battery life on flagship models now runs 30 to 300 hours depending on the brand. So why does a top Twitch streamer still run a cable across his desk?
The first reason is reliability. When you stream to tens of thousands of concurrent viewers, a headset that dies mid-stream or drops connection is not a minor annoyance — it is dead air in front of a live audience. A wire never runs out of battery, never needs a firmware update at the worst moment, and never randomly disconnects because a microwave turned on.
The second reason is signal purity. Wireless audio compresses the signal to fit through the air. Even excellent wireless headsets apply some level of compression that slightly smooths out the tiny details — exactly the details that tell you whether a footstep is 12 meters away or 8. A wired analog connection through a dedicated amp skips all of that.
The third reason is the mix control we just covered. Wireless headsets usually route everything through a single USB device, which makes independent game and chat control clunky. A MixAmp gives you a physical knob.
| Factor | Wired (A40 TR + MixAmp) | Typical Wireless Headset |
|---|---|---|
| Latency | Effectively zero | Very low but not zero |
| Battery | None needed | 15 to 300 hours |
| Signal compression | None | Some, varies by model |
| Freedom of movement | Limited by cable | Full room range |
| Mid-game mix control | Physical dial | Software or button cycling |
| Long-term cost | Higher upfront, no battery decay | Battery degrades over years |
For a casual player who mostly wants to lounge on a couch, wireless makes total sense. For someone whose income depends on hearing a single footstep at hour nine of a stream, the cable is not a compromise. It is a feature.
Jynxzi’s Broader Setup and How the Audio Chain Fits In
A headset never works in isolation. It is one link in a chain that includes your microphone, your mixer, your monitor, and even your chair. Jynxzi’s setup follows a pretty clear pattern: broadcast-quality gear for anything the audience hears, and competition-focused gear for anything that affects gameplay.
The separate microphone question
One thing that confuses newer viewers: the microphone on the A40 TR is not what you hear on stream. Most large streamers, Jynxzi included, use a dedicated broadcast microphone on a boom arm — typically something in the Shure SM7B family or a similar dynamic mic — routed through an audio interface or a mixer like a GoXLR. The headset mic stays as a backup or gets flipped up entirely.
That separation matters if you want to copy the setup. Your headset mic exists for in-game comms and console play. Your broadcast mic exists for your audience. Trying to make one device do both jobs is why a lot of small streamers sound muddy.
Typical gear categories in a setup like his
- Headset: Astro A40 TR with MixAmp Pro TR for positional game audio
- Microphone: Broadcast dynamic mic on a boom arm, isolated from keyboard noise
- Audio routing: A mixer or interface that separates game, chat, music, and alert channels
- Monitor: High-refresh 240Hz or faster competitive panel with low response time
- Mouse: Ultra-lightweight wireless model built for flick aim
- Keyboard: Low-actuation mechanical or optical switches
- Chair and desk: Built for all-day sessions, because comfort is performance
Notice the pattern. Every choice reduces friction between what happens in the game and what reaches his brain, and between what he says and what reaches his audience. That is the actual lesson, and it applies whether your budget is 2,000 dollars or 200.
Dialing In Siege Audio Settings Like a Competitive Player
Buying the same headset as your favorite streamer and leaving your settings on default is like buying racing tires and driving in first gear. Rainbow Six Siege has specific audio options that dramatically change how much information you get from sound. Here is how to set them up properly.
Step by step in-game configuration
- Open Settings and go to the Audio tab.
- Set your audio output device to your headset or MixAmp, not “Default Device.” This avoids Windows rerouting audio when you plug something in.
- Set Sound Configuration or Dynamic Range to the headphones or “Night Mode” style option. This compresses the dynamic range, meaning quiet sounds like footsteps get boosted closer to loud sounds like gunfire. It sounds less impressive and works far better.
- Enable HRTF (Head-Related Transfer Function) if the option is available. HRTF simulates how sound bends around a human head and ears, which massively improves vertical positioning — crucial in a game built around floors and ceilings.
- Lower music volume to zero or near zero. Menu and round-start music serves no competitive purpose.
- Set voice chat volume noticeably lower than game effects volume so teammates never bury sound cues.
- Test in a custom game. Have a friend walk on the floor above and below you until you can identify the direction and elevation instantly.
Windows and driver settings that trip people up
On PC, a few system-level settings quietly ruin your audio. Turn off any “spatial sound” enhancement in Windows if your MixAmp or headset already applies surround processing — stacking two virtual surround engines smears positional cues instead of sharpening them. Set your output sample rate to 24-bit, 48000 Hz, which matches what most games output. Disable loudness equalization and any bass boost checkboxes hiding in the Enhancements tab.
Finally, resist the urge to crank the volume. Extremely loud audio compresses your own hearing over time and makes distant, quiet cues harder to detect after an hour. Set a comfortable level where you can hear a distant footstep clearly and gunfire does not make you flinch. Your ears are the only pair you get, and hearing damage is permanent — something that matters a lot when your career depends on audio.
Alternatives That Get You Close for Less Money
The full A40 TR plus MixAmp Pro TR bundle sits in premium territory. Not everyone can drop that kind of money, and honestly, not everyone needs to. Diminishing returns hit hard in gaming audio. A well-chosen 80 to 130 dollar headset gets you most of the way there.
| Headset | Design | Best For | Price Tier |
|---|---|---|---|
| Astro A40 TR + MixAmp Pro TR | Open-back, wired, amped | Streamers and tournament players | Premium |
| Logitech G Pro X | Closed-back, wired | All-around competitive play | Mid |
| HyperX Cloud II / Alpha | Closed-back, wired | Comfort and durability on a budget | Budget to mid |
| Beyerdynamic DT 990 Pro + ModMic | Open-back studio, wired | Best raw soundstage per dollar | Mid |
| SteelSeries Arctis Nova Pro | Closed-back, wired or wireless | Premium all-rounder with EQ features | Premium |
| Philips SHP9500 + clip-on mic | Open-back, wired | Cheapest path to open-back sound | Budget |
The sleeper pick on that list is the studio headphone route. Open-back studio cans like the Beyerdynamic DT 990 Pro or the Philips SHP9500 were designed for audio engineers who need to hear every detail, and they translate beautifully to competitive shooters. Pair one with a clip-on boom microphone and a cheap USB DAC, and you have a setup that competes with headsets costing twice as much. The tradeoff is that you assemble it yourself and it looks less like a gaming product.
If you want the MixAmp experience without the Astro price tag, look at entry-level USB DAC and amplifier combos. Many cost 60 to 100 dollars and drive high-impedance headphones cleanly. You lose the game-to-voice dial, but you can replicate most of that with software like Voicemeeter, which is free.
Here is a realistic scenario. Say you have 150 dollars total. Spending 110 on an open-back headphone and 40 on a decent clip-on mic will almost certainly outperform spending all 150 on a flashy closed-back gaming headset with heavy bass tuning. Positional accuracy beats bells and whistles every single time in Siege.
Common Myths About Streamer Headsets
Once a piece of gear gets associated with a big creator, misinformation spreads fast. Let’s clear up the biggest misunderstandings so you spend your money wisely.
Myth: The headset is why he hears everything
Skill does the heavy lifting. Jynxzi has spent thousands of hours in Siege learning what every sound means — the difference between a Bandit battery and a Kaid claw, the specific creak of a barricade versus a wooden hatch, how far a rappel sounds on each map. Great gear amplifies that knowledge. It does not create it. Give a brand new player the exact same setup and they will still not know what they are hearing.
Myth: More expensive always means better positional audio
Plenty of 300 dollar headsets are tuned for movie-style bass because that sells units. Heavy bass actually masks footsteps through a phenomenon called auditory masking, where loud low frequencies make nearby quiet frequencies harder to detect. A flat, slightly bright headset for 100 dollars often outperforms a bass-heavy 250 dollar one for competitive use.
Myth: Virtual 7.1 surround is always better than stereo
It depends entirely on the implementation and the game. Some virtual surround engines add reverb and smearing that make positioning worse. Test both. Play a few rounds in stereo, then a few with surround enabled, and see which one lets you identify vertical positions faster. Many top players actually prefer stereo with good HRTF over generic virtual surround.
Myth: You need the exact same gear to improve
The single biggest audio upgrade for most players costs nothing: turning off in-game music, lowering voice chat relative to game sound, and enabling the compressed dynamic range setting. Do those three things and you will notice a difference in your very next match, regardless of what headset you own.
One more practical note — room noise matters more than people admit. If your PC fans howl, your keyboard clacks like a typewriter, or your family talks nearby, an open-back headset will let all of it through. In that situation, a closed-back headset with modest isolation genuinely outperforms a technically superior open-back one, because you actually hear the game instead of your environment.
Frequently Asked Questions About Jynxzi’s Audio Gear
These are the questions that come up most often in chat and on forums, answered directly.
Does he use the same headset on console and PC?
The A40 TR plus MixAmp combo works on both, which is part of its appeal. The MixAmp Pro TR was designed with console optical output in mind, and Astro sells console-specific versions. If you play on both platforms, this setup travels between them easily.
Can I use the A40 TR without the MixAmp?
Yes, it plugs into a standard 3.5mm jack and works fine. You will lose the surround processing, the EQ presets, and the balance dial, and it will sound quieter than it should because of the 48-ohm impedance. It still works — it just does not reach its full potential.
Do I need the closed-back mod kit?
Only if your environment is loud or you share a room. In a quiet space, the stock open-back configuration gives a wider soundstage, which helps positional awareness. Buy the mod kit if noise is a real problem, not because it sounds fancier.
How long do headsets like this last?
With normal use, expect three to five years before earpads flatten and cables fray. The good news is that the A40 TR uses replaceable earpads, headband padding, speaker tags, and cables, so you can refresh it instead of replacing it. That repairability is a genuine long-term value.
What is changing in gaming audio right now?
Three trends are worth watching. First, HRTF and personalized spatial audio are getting better — some systems now scan your ear shape to build a custom profile. Second, low-latency wireless keeps closing the gap with wired, and within a few years the difference may become genuinely irrelevant. Third, AI-driven noise suppression on microphones has improved so much that headset mics are becoming viable for casual streaming. None of that changes the fundamentals, though: a neutral tuning, a good seal or soundstage, and smart in-game settings will always beat marketing features.
Putting It All Together
So, to bring it back to the original question — Jynxzi is best known for running the Astro A40 TR headset paired with the Astro MixAmp Pro TR, a wired setup that trades wireless convenience for precise positional audio, zero latency, and hands-on control over his game and chat mix. That combination gives him a wide soundstage for locating footsteps, a clean amplifier to drive the 48-ohm drivers properly, and customizable EQ presets tuned to make footsteps pop out of the noise. Around that core, he layers a separate broadcast microphone, careful audio routing, and in-game settings that squeeze every drop of information out of Siege’s sound design.
The real takeaway is not to blindly copy a shopping list. It is to understand the reasoning: pick gear with accurate, neutral sound rather than exaggerated bass, give your headphones enough clean power to perform, control your mix so voices never drown out game audio, and then spend real time learning what every sound in your game actually means. Do those things with a 100 dollar headset and you will out-hear someone running a 400 dollar setup on default settings. Start with the free adjustments today, upgrade your hardware when your ears tell you it is the bottleneck, and enjoy the moment when you call out a roamer through the ceiling and your whole team wonders how you knew.
