Beyerdynamic MMX 330 Pro review: an open-back gaming headset with great sound – and not much else

Beyerdynamic MMX 330 Pro: two-minute review

The Beyerdynamic MMX 330 Pro brings the German brand’s noted pro audio pedigree to the gaming world, in the form of an open-back gaming headset that’s light on features, but promises big things in the realm of sound.

At first glance, you’d be forgiven for not realizing this is a piece of gaming hardware, given the lack of flair. The monotone palette is only slightly alleviated by specks of orange, but if you’re willing you can customize your own design via Beyerdynamic’s website.

Compared to some of the best wired gaming headsets, the MMX 330 Pro is pleasingly slim. It’s also light, which makes it comfortable. The plush ear pads and thoughtfully designed headband also help in this regard, although I did find the MMX 300 Pro to be slightly more comfortable, as the inside of its drivers didn’t push into my ears as much as those on the MMX 330 Pro.

The detachable analog cable is thick yet doesn’t weigh down the headset. The strain reliefs aren’t the strongest, so I don’t have complete confidence they’ll resist splitting over time, but they offer more protection than on some other gaming headsets. The inline controller has a volume wheel and a mute button, although there are no mic volume controls as there are on the MMX 300 Pro, which is an odd omission, but not one I missed greatly.

Unlike the MMX 300 Pro, the MMX 330 Pro sports an open-back design, intended to impart a more natural sound and create a greater sense of space. I didn’t find this added to the immersion or increased my perception of the in-game ambiance, but I personally prefer closed-back designs. There is also a loss of low-end compared to the MMX 300 Pro, which was already lacking in that department.

All this isn’t to say that the sound of the MMX 330 Pro is poor, though. True to many of Beyerdynamic’s headphones and headsets, the audio balance is superb, with most frequencies coming across clearly and precisely. In this regard, it certainly ranks among the best gaming headsets.

The microphone quality is similarly great, rendering voices with clarity and doing a good job of preventing unwanted sound from being picked up. It’s also very well made, with the gooseneck design making it easy to manipulate yet secure enough to remain in position. It can also be rotated out of the way easily.

There’s no denying that the MMX 330 Pro is incredibly expensive, even eclipsing some of the best wireless gaming headsets. Oddly, it’s also more expensive in North America, which Beyerdynamic claims is due to certain market conditions and launch timeframe concerns.

Whatever the reasons, the fact is there are gaming headsets available that pack in more features for less money, yet still provide terrific audio quality. If you don’t mind sticking to cables, then the Epos H3 wired gaming headset is a brilliant alternative, and for those who want less clutter, the Razer BlackShark V2 Pro is one of the best wireless gaming headsets around.

Beyerdynamic MMX 330 Pro review: price and availability

• $329 / £259 / AU$499
• Black only (unless customized)
• More expensive in the US

The MMX 330 Pro costs $329 / £259 / AU$499 and is available in black only. However, you can customize it with your own designs via Beyerdynamic’s website, letting you add engravings and your own photos to have emblazoned on the drivers.

The MMX 330 Pro costs the same as the MMX 300 Pro in the UK, EU, and Australia; in the US, however, it’s more expensive: $329 as opposed to $299 for the MMX 300 Pro. Having contacted Beyerdynamic, a representative explained the increase comes down to regional costs and distribution logistics, as well as the headset’s launch timeline. Regardless, it’s still a bad deal for those in North America.

The only major difference between the 300 and the 330 is the open and closed-back designs. I did, however, notice a softer earpad material on the MMX 330 Pro, and the lack of mic volume controls on the inline controller.

For a wired gaming headset, the MMX 330 Pro sits towards the higher end of the market. The Epos H3, one of the best wired gaming headsets, is much cheaper. In our Epos H3 review, we were very impressed with its detailed audio quality, which made it great for both gaming and listening to music. There is also a wireless version available in the form of the Epos H3 Hybrid, although this is close to the same price as the MMX 330 Pro.

The MMX 330 Pro is also considerably more expensive than the best wireless gaming headset, the Razer BlackShark V2 Pro. Not only does this headset ditch the cables, but it also has more features, including software that allows you to alter various sound settings and modes.

Beyerdynamic MMX 330 Pro review: design and features

• Surprisingly slim
• Not quite as comfortable as the MMX 330 Pro
• No extra features

In line with Beyerdynamic’s other headsets, the MMX 330 Pro adopts a muted aesthetic, with only a few dashes of orange contrasting with the monochromatic color scheme. It certainly isn’t as brash as some other gaming headsets, which may or may not please players depending on their preferences.

For a gaming headset, the MMX 330 Pro is refreshingly slender, with minimal protrusion from the drivers. Beyerdynamic’s other headsets can verge on the unwieldy, including the MMX 200 Wireless, which is also less comfortable. The MMX 330 Pro still isn’t what you’d call portable, though, and the lack of driver swivel means they aren’t the easiest to hang around your neck.

Compared to the MMX 300 Pro, the earpad material here is more plush and feels slightly baggier but also softer. The thickness of the cushioning is about the same, but it didn’t feel quite as comfortable, with the inside of the drivers pressing into my ears with more force than those on the MMX 300 Pro. This isn’t to say the MMX 330 Pro is uncomfortable, but fatigue did set in sooner than it did with the MMX 300 Pro.

The headband, though, is just as excellent as it is on the MMX 300 Pro. The fontanelle that helps to relieve pressure at the top of the head really does work, and I experienced hardly any aching on the top of my head after extended sessions with the MMX 330 Pro, which I am liable to feel with many other headsets. It also seems durable, although it is easily replaceable (as are the earpads).

The detachable 3.5mm analog cable feels premium, although the strain reliefs don’t appear to be the most resilient, so I wouldn’t be surprised if they began to split over time. They also attract dust too easily, which is hard to remove. It’s also hard to tell when the plug is fully inserted into the headset socket – again similar to the MMX 300 Pro – as there’s no audible click or physical feedback, but this is a minor gripe.

Despite its length, the cable has no noticeable effect on the weight of the MMX 330 Pro when wearing it. And as with the best PS5 headsets, it’s unobtrusive when plugged into a DualSense controller, making it easy to use with the console.

The in-line controller feels well-made too. It features a volume wheel that operates smoothly and a mic mute button. However, there are no mic volume controls as there were on the MMX 300 Pro, which may bother some people, but I rarely used them when they were present.

One issue that’s plagued every Beyerdynamic headset I’ve tried is the poor driver height adjustment, and the MMX 330 Pro is no exception. The mechanism feels clunky and stiff, making it hard to maneuver, and while it does offer a secure hold once set in position, the engineering isn’t on par with the rest of the headset – and isn’t what you’d expect from a gaming headset at this price point.

The microphone is, however, up to the standards you would expect. The gooseneck is easy to adjust yet secure, and the cloth tip feels thicker and more durable than on other gaming headsets. Although it doesn’t detach or retract, it can be rotated 360 degrees, allowing you to move it out of the way completely.

As with the MMX 300 Pro, there are no extra features on the MMX 330 Pro. The simplicity is refreshing, letting you plug and play without having to worry about connectivity and setups. However, for a gaming headset at this price, more adjustments and settings would’ve been welcome, so you could dial in the perfect sound according to your individual preferences.

Beyerdynamic MMX 330 Pro review: performance

• Great gaming sound
• Open-back design lends more space
• Weaker low-end than the MMX 300 Pro

Beyerdynamic’s famed audio quality is present and correct on the MMX 330 Pro, with frequencies appearing crisp and clear. Beyerdynamic claims the open-back design adds a greater sense of space, allowing you to perceive sounds more naturally.

While gaming, I did notice a more airy sound, but I wouldn’t exactly call this an improvement. The claim that it makes it easier to tell where sound is coming from wasn’t something I experienced during my time with the MMX 330 Pro.

Personally, I prefer the isolation and depth of sound you get from closed-back headsets. Beyerdynamic points out that it has less bass than the MMX 300 Pro because of the open-back design, and this is noticeable. The low-end of the MMX 300 Pro was already a touch on the weaker side, but here it is even more so. It’s not completely devoid of impact, but if you’re going to be using a headset for listening to music as well as gaming, then the 300 Pro is the slightly better choice.

As with the MMX 300 Pro, the microphone on the MMX 330 Pro renders voices with clarity and precision, and blocks unwanted noises from registering with aplomb, including coughs and other plosive sounds.
