Beyerdynamic MMX 300 Pro Vs MMX 330 Pro Comparison Review

Beyerdynamic has added two new gaming headphones to their selection with the MMX 300 and 330 Pro. These are closed-back and open-back headphones respectively, offering an option to whichever type of headphones you prefer. Is one opinion completely better than the other though? Here’s what the MMX 300 and 330 Pro can do to enhance your game audio.

Look & Feel

Both headphones have nearly the same build, with the only difference being the 330’s small open-back grilles. Otherwise, both headphones have a sturdy build that is the same quality as their professional studio headphones. They have quality aluminum yokes, big earcups, and thick velour earpads that are very comfortable for long hours of gaming. There’s also a nice padded headband that also makes the headphones feel snug, but there’s also a pinch to it that causes both headphones to have a level of clamp to them.

Design

Beyerdynamic has a new driver configuration that can be seen in both the MMX 300 and 330 Pro. These are 45mm STELLAR.45 drivers that help ensure a studio-level sound that is unique compared to most gaming headphones on the market.

Mic Quality

The MMX 300 and 330 Pro both have some of the best headset mics on a pair of gaming headphones. They’re quality condenser mics with a cardioid pattern that is very clear for voice chatting with your friends.

Soundstage

Comparing an open-back to a closed-back headphone might not be fair, but if you’re looking for the best soundstage, the open-back 330 Pro is the way to go. The MMX 300 Pro has a great soundstage for a closed-back headphone though, and you can still enjoy spacious game audio even with its more isolated nature. Both headphones portray accurate spatial imaging, which is very helpful in certain games. With the 330 Pro, you’re able to get a better sense of distancing and the angle of the sound, whereas the 300 Pro just points you in the right direction. The 330 is also better at communicating high-fidelity ambiances that stand out in front of you, while the 300 lacks the headspace to differentiate foreground and background.

Low End

Closed-back usually means a more concentrated, aggressive bass. This is partially true for the MMX 300 and 330. The bass frequencies jump out at you more prominently on the 300, forming a more thunderous frequency response compared to the 330. It carries a lot more weight to its tone, while the 330 has a more neutral response. I think the timbre of the 300 suits gaming better than the 330 in this way. The bass feels a lot more theatrical, which gave me a more consistent and gratifying experience will most games. You can sometimes hear a better sub-bass response in the 330, but the 300 has better textures for big game sounds.

Mids

Both the MMX 300 and 330 Pro have good midrange detail. I would consider them to be two of the best gaming headphones for this. They still have their quirks though, like the 300 taking on a more neutral timbre compared to the 330’s lusher presentation. You can hear how punctual both of these headphones sound compared to a lot of other gaming headphones on the market. Just by how the 300 and 330 balance dialogue and music in a natural way. The 330 has slightly more breathable room in its midrange, but the way it handles detail retrieval isn’t all that different compared to the 300.

Highs

You might hear the name Beyerdynamic and assume the 300 and the 330 have dominant treble, but these headphones are quite different. They’re actually both very reserved when it comes to the high frequencies. not much is lost in terms of presence and clarity, but the feeling of the treble is toned down significantly in both the MMX 300 and 330. Neither the 300 nor 330 contain any harsh brightness or piercing tones. In terms of detail, the 330 might have a bit of an edge in its height, but they have a similar timbre otherwise.

Summary

If you’re trying to make a decision between the two headphones, it really comes down to which driver principle you prefer. In terms of sound, the only significant differences are the enhanced soundstage of the 330, and the more impactful bass of the 300. Otherwise, both of these headphones have similar levels of detail retrieval, which is good for adhering to a specific sound standard across the board.
