Quick Summary
The Beyerdynamic MMX 330 Pro is a perfect headset for competitive FPS players. It has a sharp, detailed sound signature and its open-back design results in a wide soundstage. If you can deal with the limitations of the wire and weight, the MMX 330 Pro is definitely the device to pick.
Connectivity and Controls
This is a wired, open-back headset with an included detachable 3.5 mm cable. It's very long at 103 inches, plus a few more on the adapter. The wire splits into a mic and headphone audio output, and the adapter combines them into one 3.5 mm end to be used in a controller or a combo jack on PC.

This has an impedance of 48 ohms which makes it relatively easy to power by just a motherboard or even a controller. Because it's 3.5 mm it works on PC, Xbox, and PS5.
The only controls are on the cable: volume and mic mute.
Headphone Audio Quality
The MMX 330 Pro has 45 mm drivers called “STELLAR.45”. Combined with the headset’s form factor and materials, they sound insanely good. This is unapologetically a treble forward headset, but every frequency is well represented. These are the most receptive headphones to EQ that I've used.
In FPS games, footsteps stand out perfectly. The same goes for grenades, reloads, and other important cues. The bass gets very deep all the way through the subbass to make it distinct from the rest of the audio, but it's very controlled.
These are still considered open-back even though the vents aren’t that large.
The midrange sounds natural and not overly nasally, and the treble has excellent detail - it's not the harshest, but it’s definitely sharp if you're not used to it. Because of the open back design letting the bass vent out, the soundstage is very wide in comparison to most other gaming headsets. In layman’s terms, if something is supposed to sound far away in a mix, it will in the 330 Pro.
Personally, I found this to be more relevant in more immersive games that have busier mixes. In Horizon Forbidden West, all the sounds in a forest like birds chirping or standing near a waterfall really sound like they surround the character rather than everything seeming close up.

By dropping down the upper mids and treble while boosting the bass in SteelSeries Sonar, I really enjoyed playing single player games and listening to music with this. But I stick to default for FPS and most other use cases.
Overall these get a 10/10 sound for FPS games and I'd probably enjoy the closed back version even more for other use cases.
Microphone Audio Quality
The microphone is above average. Like most gaming headset mics, it’s a bit too sibilant. The passive background noise rejection is pretty good - especially considering this is a condenser.
This does suffer from plosives if it's too close to your mouth. Unfortunately, since it's not that loud, moving the mic farther away will require you to boost it in whatever software you have.
So, good mic, just not amazing.
Comfort and Build Quality
I really love the comfort and build of this headset. It's mostly plastic, but the adjustment forks are made of metal. I weighed my unit at 316 grams. The headband is button-on so it can be replaced, and there’s some memory foam where it meets your head.
The velour ear cushions keep in enough sound so that you can physically feel some bass, but not quite to the degree of pleather.
Overall this gets a B+ in comfort. The only thing that keeps it from an A is the weight starts to become annoying during marathon sessions.
Verdict
I highly recommend the Beyerdynamic MMX 330 Pro especially for FPS players. The detail is incredible and it’s very comfortable.
For general everyday use or single player gaming it’s still an amazing device, but the price is probably overkill. Also, bassheads may be more interested in the Astro A50 Gen 5 (my article) or EPOS PC38X with velour pads.
