Our review
Ergonomics
How do you recognize the audiophile ambitions of a gaming headset right away? Most of the time, to its aesthetic sobriety. The MMX 300 is an illustration of this, with its matt black finishes of total discretion and its forms simply taking the typical design of Beyerdynamic helmets. Anyone who has already placed one of the German manufacturer's DT series helmets on their head (DT 770, DT 880, DT 990 ...) will find themselves in perfectly familiar terrain when fitting their little brother dedicated to the game.
We can only rejoice, since this makes the MMX 300 a very comfortable helmet, capable of adapting to the vast majority of body types and which can be worn for hours without any discomfort - or almost. We would have simply appreciated the use of slightly thicker foams, which might have slightly lessened the feeling of pressure that can appear on the base of the jaw. Nothing to say however on the side of sound insulation, excellent.
The velvet pads can very easily detach from the ear cups - and be replaced, since Beyerdynamic offers them for sale in spare parts. The same goes for the headband cushion, which is covered with imitation leather and attached with a simple velcro.
On the other hand, the microphone is welded to the left atrium of the helmet, and is not retractable either. It is certainly mounted on a pivot allowing it to be raised vertically, but it then forms an inconspicuous and unattractive appendage.
The MMX 300 is supplied with two detachable cables: one measuring 1.2 m and ending with a 4-point mini-jack, the other measuring 2.5 m and ending with two separate 3-point mini-jack; the second is obviously indicated for use with a fixed PC, while the first will go perfectly with modern game consoles (PS4, Xbox One, Switch) and mobile platforms. The short cable even has a one-button remote control to pause / play and answer calls.
Both cables also have an analog volume control dial. As always, we can not help seeing this with a suspicious eye, since the volume control potentiometers are often of quite relative reliability: how many months, even weeks before one of them starts to "spit" and destroy the volume balance between the left and right ear cups? It is all the more annoying here that the connection between the headphones and the cable is made via a proprietary connector. Admittedly, there again, the manufacturer offers replacement cables for sale, but we would have greatly preferred not to have to ask these questions. It is this only point that pushes us not to assign the maximum score to the MMX 300 on this part devoted to ergonomics.
To conclude all the same on a positive note, Beyerdynamic has the charming attention of offering its helmet with a rigid storage box allowing to transport it with confidence. Finally, note the inclusion of a 6.35 mm jack adapter, a testament to the hi-fi ambitions of this helmet.

Audio
And let's say it straight away and unadorned: without the slightest challenge possible, the MMX 300 proves perfectly worthy of its ambitions.
Beyerdynamic's helmet produces a very balanced reproduction, without however achieving perfect neutrality. A slight V-shaped signature is heard, giving the sound a turn that is both fairly warm - a consequence of the emphasis on low frequencies - and very incisive, due to a significant energy peak around 8 kHz - peak greatly exaggerated on our curve due to a measurement artifact, but still real. This peak, however, is not annoying here, because the treble is also perfectly controlled and precise. No trace of distortion to deplore, no more than a parasitic flicker; on the contrary, the top of the spectrum lets perceive a very generous amount of detail and richness - of a kind that we actually usually associate much more readily with a very demanding hi-fi headset than with a gaming product. Admittedly, we cannot however promise that this little extra nervousness will be to everyone's taste, and some users will find it more difficult than others to get used to the slightly grainy side that it brings to the sound. In absolute terms, however, we can not blame him, especially since it works as well in music listening as on audiovisual content.
It might be feared that such a profile could cause some hearing fatigue during long listening sessions, but this is fortunately not the case. In the high mids, there is a slight dip in the cutting edge, around 3 and 4 kHz, a characteristic common to many gaming headsets; but it is here very little pronounced enough to cause no loss of naturalness or any deficit in presence. Instead, it prevents the sound from falling into hardness and relieves the ear on these frequencies which are those to which it is most sensitive. What's more, this frequency zone can once again boast impeccable precision, which allows the MMX 300 to shape an extremely clear soundstage, where the appreciation of distances to sound sources is perfectly easy. Already very effective in "simple" stereo, these qualities also go perfectly with binaural spatialization treatments such as Dolby Atmos for Headphones. Ideal for admiring the abundant soundscapes of today's games in great detail.
There is hardly that in the serious ones that one finds a small reservation to formulate towards the helmet of Beyerdynamic. Certainly perfectly clean, the low frequencies still lack sometimes an ounce of control and sharpness. We would certainly not qualify them as messy, but we can find them slightly purring and too little "punchy". Rest assured, the overall sound base remains more than satisfactory, in particular thanks to an excellent extension of the sub-bass that easily descends below 20 Hz.
At the time of the final assessment, this small annoyance therefore does not prevent the MMX 300 from being close to excellence in terms of audio reproduction and hovering well above the mass of headsets "for players".

Microphone
As we said above, the Beyerdynamic MMX300 is equipped with a non-detachable and non-retractable gooseneck microphone. However, the pivot on which it is mounted allows a wide latitude as to its placement in front of the mouth - all the more since the malleability of the pole is ideal.
As for the voice capture that this microphone offers, it is simply impeccable. Not only is the timbre of the voice reproduced in a perfectly natural way, but the extreme directivity of the microphone means that almost no surrounding noise risks disturbing its intelligibility. The icing on the cake, the included windshield provides extremely effective protection against breath noise and plosives. Absolute flawless.
! [. Signal amplified to +10 dB, no other processing applied.] (An oral conversation takes place less than 3 meters away)
Finally, note the fairly high sensitivity of the microphone, which allows you to be heard perfectly by your game partners even without having to activate any amplification. At most, people with particularly calm voices can allow themselves +10 dB - but be careful not to get too caught up in the heat of the moment: saturation awaits ...

Conclusion
The Beyerdynamic MMX 300 easily establishes itself as a reference for headsets - not to say the reference. It benefits from its first-rate sound reproduction, just tinged with a light but fairly incisive V signature, which could slightly disconcert some users; but this is only a matter of personal preference. Add to that a microphone among the very best encountered on a gaming headset, excellent comfort, a robust design - except for these damn analog volume controls - and easily repairable ... You have to search long to find small reproaches to do to this helmet .

Reviews
Amazing sound and comfort.
TL; DR This is the best gaming headset ive used. It checks all the boxes: great sound, super comfy, great isolation, built in mic.
Not sure how these things aren't the next big thing. (lack of marketing perhaps? not a "gaming" company?) I have used many gaming headsets over the years, wired and wireless and there are some decent ones; the one thing they all lacked was GREAT sound. Many sounded good, but not great. many also sounded like muddy poo ... I've recently gone back to not only wired setups (wireless, while convenient, has other compromises) but good headphones; not headsets with mic. I've been using a modmic 5 or vmoda boom mic for voice. I've only heard good thing about Beyerdynamic for sound quality and comfort and was looking into their DT770 or 880 headphones. While reading their site, I stumbled upon their "Gaming" section and found they made a headset; two of them in fact.
The audio specs on the MMX 300 2nd Gen look identical to that of the DT770. Some googling showed these were relatively new (debuted at CES 2017) and even found a few reviews from the past couple months. I took a chance on them and im glad i did.
SOUND
These are not flat but they aren't v-shaped either. There is a slight bass boost perhaps but the mids and highs are still present and clear. Starting at the bottom, the bass is nice and deep but its not boomy or muddy. It is very tight and detailed with no distortion. Mids are not recessed. I found footsteps to be very easily heard which helps a ton. Highs are very good, not recessed and not ear piercingly bright either. They are damn near perfect. The sound profile on these is perfect for gaming and I think anyone would be happy with them for music listening too. The sound stage is the widest ive heard from a closed back earcup. The stereo seperation is amazing; the closest ive gotten to open-backs. I can much easier pinpoint locations of enemies and footsteps compared to other headsets ive used.
The mic works great. its a flexible "wire" arm that stays wherever you put it. It will rotate up out of they way if i dont want to use it. Comes with a pop filter. My only complaint is it is not removeable. To the negative review here where the user thought the mic was bad, it probably was physically defective. I have no problems with mine; clean and clear.
COMFORT
If im gaming for a few hours, i want a comfy headset. These are it. the huge plush earcups circle my ears, are soft and breathable; no sweaty ears. The headband is pillowy soft and like the earcups, fully replacable should it wear out from skin / hair oils. These are also super light weight which helps. I've had some heavy wireless headsets that become uncomfortable and / or fall off if i tip my head too far forward or back due to weight and gravity.
STYLE
These are understated. All black, no facy LEDs (who actually wants LEDs on a headset, on your head, that you cannot see while using?). These have no bling and that is fine. They are plasticy with some metal in the headband / arms. To be honest, they dont feel like an expensive pair of cans; but i dont care. That is probably the least important thing. Funtion over form here and they've nailed function.
OTHER
This is a stereo headset, no gimmicks like surround sound. If you want your sound experience to sound like everything is in bathroom, look elsewhere. no fake 3d reverb effects here. The inline control pod has one of the best mute switches ever. most are tiny little switches on the side and you have to fiddle to find it. this is a large slider and is super easy and convenient. The earcups are velor and suprisingly seal really well. No active noice cancellation but the passive isolation is great. Definitely one of the better isolating sets ive used. One note i will caution others on, make sure you plug the cable into the headset ALL THE WAY. it is a very tight fit and my first attempt wasnt fully inserted and i was only getting 1 channel of audio. there really isnt a well defined click either when fully inserted which doesnt help.
To sum up, buy these if you care about amazing sound quality and the convenience of an integrated mic and haven't been happy with the rest of the so-called "gamer headsets". this is audiophile quality sound that also just happens to be a gaming headset and cant be matched by anything else short of other audiophile headphones and seperate mic.
Where have I been? oh, broke!
I have been through the Astro a40, HyperX Kingston Revolvers, and multiple Turtle Beach's. This headset is by far the cleanest and sharpest sounding headset that I have ever heard. I have zero hiss when the mixamp is cranked and it handles everything at loud volume with ease. I am powering these with the Astro TR Mixamp. The sounds actually sound layered and you can pinpoint where things are coming from. Unlike the previously mentioned headsets, the sounds all run together and there isn't as much distinction. All in all, if you are looking for the best gaming headset with the most precision in locating enemies, get these! If you are wanting save a few bucks but want a 'larger sound' go with the GSP 600 headset. I bought the MMX 300 on sale for 265 but they are usually 350.
* edit *
I forgot to mention how comfortable they are. The ear cups are super soft and create a nice seal around my ears. The headband is wrapped in a cushioned leather like wrap which is easy to replace. And the mic! I heard that this mic from their aviation line of headsets used in helicopters! Everyone says that I sound fantastic after switching to the MMX 300. They thought I bought a fancy stand alone mic. The case is oval shaped. It has an exoskeleton all the way around with soft padding on the inside.
Glorious
I've gone through a lot of gaming headsets over the years but I've never found one that was the “one”. Until now.
I've had this headset for five months now and I couldn't be happier. Comfort is a major influence in my purchases and I was at first worried about the circular earcups, as they tend to press against my ears and cause cartilage cramps. But these are hefty, big enough that they surround my ears no problem. They are also incredibly light, so no having to worry about them tiring your head out.
And of course the sound is amazing. I have them paired with an Astro mix amp and it's great, but they can perform very well without an amp. I'm no audiophile but after using a bunch of headsets these have sounded the best, and the mic is fantastic to boot, people can hear me nice and clear with no problems.
My one initial gripe I had was the clamping force, as it was a bit too tight for my liking at first, and one who wears glasses I have to kinda fidget them about to get it right. However after a while I got used to it, and now what was once a gripe is just an afterthought, but it's somethig to consider if you have a larger head like myself and wear glassses.
Overall though this is the best headset I've ever owned, definitely worth the price.
