The Beyerdynamic MMX 330 PRO are wired gaming headphones from the veteran German audio manufacturer. They feature an open-back design that allows sound to escape the ear cups, which can help emulate the spacious sound you get with speakers. Their understated aesthetic calls to mind the brand's audiophile offerings, like the Beyerdynamic DT 990 PRO, but this model stands apart with its gamer-friendly features, like a gooseneck condenser microphone and in-line controls.
Our Verdict
The Beyerdynamic MMX 330 PRO aren't suitable for sports and fitness. Their bulky, wired design and relatively heavy weight mean they lack stability, and the cable can easily get snagged on things during exercise. While they're quite comfortable, the velour earpads can easily trap sweat around your ears if you use them for more vigorous activities.
Comfortable fit.
Heavy, bulky design.
Boom mic isn't detachable.
The Beyerdynamic MMX 330 PRO aren't suitable for travel. While they have a comfortable fit, they're bulky headphones that lack a carrying case, so bringing them on the go can be a challenge. Furthermore, their open-back design contributes to their poor noise isolation, leaving you at the mercy of rushing traffic noise and chattering pedestrians. They also leak a lot of audio, so there's a good chance they'll disturb your fellow commuters if you use them on the train.
Comfortable fit.
Bad noise isolation (by design).
Lots of audio leakage.
Boom mic isn't detachable.
The Beyerdynamic MMX 330 PRO are passable for office work. Their main caveat is their open-back design, which leaks plenty of audio into your environment and provides very little attenuation of external noise, so you'll hear your co-workers chatting while they hear a tinny approximation of your tunes. That said, they're comfortable enough to wear in the office all day, and their good microphone performance makes them a solid choice for calls and online meetings.
Great mic noise handling.
Comfortable fit.
Bad noise isolation (by design).
Lots of audio leakage.
The Beyerdynamic MMX 330 PRO can't be used wirelessly as they're wired-only.
The Beyerdynamic MMX 330 PRO are good wired gaming headphones. Their comfortable fit and strong microphone performance make them a solid option for gaming in quiet environments, where you don't have to worry about external distractions making their way into your audio or leaked audio disturbing others. Their wired design ensures low-latency performance, with a variety of connectors that allow for compatibility with PCs, consoles, and smartphones. Sound-wise, their balanced mid- and treble-range reproduction helps render dialogue and in-game comms with plenty of detail, though the roll-off in the bass range can take some of the boom out of explosions.
Great mic noise handling.
Sturdy build.
Comfortable fit.
Heavy, bulky design.
Bad noise isolation (by design).
The Beyerdynamic MMX 330 PRO are good for audio reproduction accuracy. Their frequency response generally follows their bright sound profile, with only minor fluctuations in the treble range that don't affect in-game audio too much. That said, our unit exhibited some mismatches between the L/R drivers in terms of phase and amplitude, with bass-range sounds skewing to the left. Driver matching tends to vary between units, though, so it's possible other units won't have this issue.
The Beyerdynamic MMX 330 PRO have bad noise isolation. Their open-back design provides only a small amount of treble-range attenuation, helping to cut down the whir of the fans in your PC tower. That said, external noise from the rest of the frequency range will make its way into your audio, so you're better off using these in a quiet environment that's free from distractions. Their design also results in a lot of audio leaking into your environment, so those nearby can hear a tinny version of what's playing in your headphones.
The Beyerdynamic MMX 330 PRO have good microphone performance. The condenser boom mic is able to render your voice in a clearly understandable way, though it can sound a little boomy and muddy, particularly if you have a deeper voice. The mic's able to separate your voice from its background impressively well too, in the face of both consistent, low-level noise and sudden, louder sounds, so your teammates will be able to hear your commands even if you're gaming in a communal space.
The Beyerdynamic MMX 330 PRO have great frequency response consistency. They deliver audio very consistently between different gaming sessions, so long as you take the time to adjust the fit. Your anatomy doesn't influence audio delivery much either, as their design ensures features like larger heads or long hair don't disrupt the seal. That said, the arms of glasses can break the over-ear seal slightly, resulting in a reduction in bass delivery.

Popular Headphone Comparisons
The Beyerdynamic MMX 330 PRO are open-back gaming headphones with a boom mic. They boast a similar build quality, comparable mic performance, and a comfortable fit to the Beyerdynamic MMX 300 (2nd Generation), but the two have very different sound profiles, as the closed-back MMX 300 reproduces a lot more bass, while also amping up the treble range for a more exciting sound overall. The MMX 300 model also come with a carrying case for easy portability, and their design helps attenuate more background noise. In comparison, the MMX 330 PRO's more subdued bass and treble response can be easier to listen to during long gaming marathons, as a sharp high-end can cause ear fatigue over extended listening. While the market for open-back gaming headsets is still relatively niche, the MMX 330 PRO face stiff competition from the ASUS ROG Kithara, which feature a more balanced sound profile, better build quality, and a more comfortable fit. So, unless you're a fan of the Beyerdynamic sound or prefer a particularly rolled-off bass range, most people will find better value in the ASUS.

The ASUS ROG Kithara are better open-back gaming headphones than the Beyerdynamic MMX 330 PRO. The ASUS are better-built and more comfortable and are capable of outputting a lot more bass than the Beyerdynamic, while maintaining a balanced mid- and treble-range that's well-aligned with our target. Both headphones have a good mic performance with solid noise handling, but considering they retail for a similar amount, the ASUS offer better value for your money.
The Beyerdynamic MMX 330 PRO are the open-back version of the Beyerdynamic MMX 300 (2nd Generation) and choosing between them will largely come down to which sound you prefer. The two models have a very similar design, similarly high build quality, and very comfortable fits. That said, the difference in enclosure means they reproduce audio very differently. The closed-back MMX 300 have much more low-end but also reproduce a sharper treble range, for a more excited (though potentially fatiguing) sound overall. Meanwhile, the open-back MMX 330 roll off a lot of low-end but have a more subdued treble response. While sound preference plays a big role in a buying decision, it's also worth noting that the MMX 330's open-back design leaks a lot of audio and struggles to provide any passive attenuation of your surroundings, so they're better suited to quiet environments.
The Philips SHP9500 are a good, budget alternative to the Beyerdynamic MMX 330 PRO if you prefer open-back gaming headphones and don't need mic support. They offer a similar sound profile, with a rolled-off bass range and some extra mid-treble emphasis. The Philips are more comfortable than the Beyerdynamic too, though they aren't quite as well built. Still, if you want the simplicity of a built-in mic, the Beyerdynamic's boom mic does a great job of rendering your voice in an understandable way, while separating it effectively from its background.
The Drop + Sennheiser/EPOS PC38X and the Beyerdynamic MMX 330 PRO are both open-back gaming headsets with similar strengths and weaknesses, though there are a few trade-offs that can help you make a buying decision. The two headphones have similar sound profiles that roll off the bass and keep mids detailed and present, though the Beyerdynamic has a sharper treble range. They have a similar build quality too, though the Drop + Sennheiser have a more comfortable fit and a better mic recording quality, which make them a better choice for most people.
