You know the drill. You’re sitting there with a pair of legendary studio headphones on your head and a separate, chunky microphone arm blocking half your monitor. It’s the "pro" look, sure, but it’s a cable management nightmare. Then Audio-Technica decided to do something that felt long overdue: they took the drivers from the most famous studio monitors on the planet and slapped a high-end condenser mic on them. That’s basically the Audio-Technica ATH-M50xSTS, or as they call it, the "StreamSet." It’s a weirdly specific name for a product that honestly solves a problem most of us just accepted as a fact of life.
The first thing you notice when you pull these out of the box isn't the weight—it’s the pads. If you’ve ever worn the standard M50x for more than three hours, you know the "ear sweat" struggle is very real. With the STS, they actually include two different sets of pads. One is the classic pleather that seals in every bit of bass, and the other is a hybrid mesh-and-leather situation that lets your skin breathe. It’s a small detail, but for anyone pulling an eight-hour stream or a marathon editing session, it’s a literal lifesaver.
What's actually inside this thing?
Let's talk about the microphone because that’s the real reason this exists. Most "gaming" headsets use tiny electret capsules that make you sound like you’re calling from a drive-thru in 2004. The Audio-Technica ATH-M50xSTS uses a 20-series condenser capsule. For the gear nerds out there, that means it’s effectively the same tech found in the AT2020, a microphone that has basically lived in every entry-level studio for the last decade. It’s crisp. It’s clear. It handles plosives—those annoying "P" and "B" sounds that pop—better than any headset I’ve touched.
The boom arm is beefy. You flip it up to mute, which is a satisfyingly tactile way to go dark if someone walks into your room mid-recording. No fumbling for a software button or a tiny switch on the cable.

The Two Versions: XLR vs USB
This is where people usually get tripped up. There isn't just one Audio-Technica ATH-M50xSTS. There are two, and they serve completely different masters.
The digital version, the ATH-M50xSTS-USB, is the one most people will gravitate toward. It’s plug-and-play. It has its own internal A/D converter that handles up to 24-bit/96kHz audio, which is way higher quality than what your motherboard's built-in sound card is doing. It also gives you a sidetone dial. If you’ve ever tried to talk while wearing noise-canceling headphones, you know you end up shouting because you can't hear yourself. Sidetone pipes your own voice back into your ears so you stay at a normal volume.
Then there’s the XLR version. This one is for the purists. It has two tails: one standard 3.5mm (with a 1/4" adapter) for the headphones and a three-pin XLR connector for the mic. You need an audio interface like a Scarlett 2i2 or a GoXLR to use this. Why bother? Because you get to use your own preamps and hardware compressors. If you’re a professional broadcaster, this is the one you want. It keeps your signal chain pure.
How it actually sounds when you're listening
If you’ve heard the original M50x, you know what to expect here. The 45mm large-aperture drivers are identical. They aren't "flat" in the way a clinical audiophile might want, but they are "true." There’s a slight bump in the lower mids that gives drums a nice kick, and the highs are sharp enough to catch a hiss in your recording without being physically painful.
I’ve found that the Audio-Technica ATH-M50xSTS excels at monitoring your own voice. Because the frequency response is so familiar to anyone in the industry, you can trust what you’re hearing. You aren't guessing if your voice sounds too bassy because the headphones aren't coloring the sound with some "Extreme Bass Boost" marketing gimmick.
The Competition and the Trade-offs
Is it perfect? No. Honestly, it’s a bit bulky. If you have a smaller head, the clamping force—which is famous on the M50 series—might feel a bit aggressive for the first week or so. You have to break them in. I usually stretch mine over a stack of books for a night to loosen the headband.
Also, it doesn't fold up. The original M50x folds into a tight little ball for travel. Because of the boom mic on the STS, you lose that portability. This is a "stay at your desk" tool. If you’re looking for something to use on a plane, this isn't it. You’ll look like a helicopter pilot, and the long, non-detachable cable will get caught on everything.
Speaking of the cable, that’s my biggest gripe. On the standard headphones, the cable is detachable. On the Audio-Technica ATH-M50xSTS, it’s hardwired. If your cat chews through that cable, you aren't just buying a $20 replacement from Amazon; you’re looking at a repair job. It’s a trade-off for the specialized wiring needed to get the mic signal out of the same housing, but it’s something to keep in mind.
Why this matters for the 2026 creator landscape
We've moved past the era where "good enough" audio works for YouTube or Twitch. Everyone has a decent camera now. The differentiator is audio. The Audio-Technica ATH-M50xSTS bridges the gap between the casual gamer and the professional broadcaster. You get the AT2020 sound without the desk clutter.

It’s about efficiency. When you can sit down, plug in one USB cable, and have studio-grade monitoring and studio-grade vocal capture, you spend more time creating and less time troubleshooting why your PC isn't recognizing your external interface.
For most people, the USB version is the winner. The convenience of having the high-quality DAC (Digital-to-Analog Converter) built right into the headset means your audio quality remains consistent regardless of which computer you plug it into. If you're traveling for a tournament or a podcast guest spot, that consistency is worth its weight in gold.
Real-world performance notes
I tested the mic in a room with a noisy AC unit. Condenser mics are notoriously sensitive—they pick up everything from the hum of a fridge to a neighbor's dog. The cardioid pattern on the STS mic does a solid job of rejecting off-axis noise, but it’s still a condenser. It’s going to be more "airy" than a dynamic mic like a Shure SM7B. You might need to use a little software noise gate if your room isn't treated.
But the clarity? It’s unmatched in the headset category. You can hear the "texture" of a voice. It doesn't sound processed or squashed.
Actionable Steps for New Owners
If you decide to pick up the Audio-Technica ATH-M50xSTS, do these three things immediately to get the most out of it:
- Switch to the hybrid pads: Unless you are in a literal loud construction zone, the mesh-hybrid pads provide a much better soundstage and won't make your ears overheat after an hour.
- Adjust your gain correctly: If you're using the USB version, don't just crank the Windows volume to 100. Find the sweet spot where your voice peaks around -6dB in your recording software. This prevents digital clipping which sounds terrible on this high-resolution capsule.
- Position the boom properly: Don't put the mic directly in front of your mouth. Position it slightly to the side of your lip. The pop filter is good, but no filter can stop a direct blast of air from a heavy breather. Placing it at the corner of your mouth maintains the clarity while eliminating the "wind" noise.
The Audio-Technica ATH-M50xSTS isn't just a pair of headphones with a mic attached; it's a piece of specialized equipment that respects the fact that creators are often their own engineers. It takes the guesswork out of the signal chain. While the hardwired cable is a bummer, the sheer audio quality makes it the current king of the "all-in-one" setup for serious vocal work.
