The Beyerdynamic MMX 300 is truly THE best gaming headset on the planet. Amazing audio quality, extremely comfortable ergonomics, and a rugged design all in a singularly steampunk package. Now this review is not all sunshine and rainbows, so be sure to read the final disclaimer below. However, the MMX 300 is likely the closest thing to an ‘audiophile quality’ headphone currently available in the gaming world.

Essentially the MMX 300 is the Beyerdynamic DT 770 headphones with an attached microphone and a slightly different carbon fiber look to the earcups; this is a good thing because the DT 770 are no slouch cans. The most impressive MMX 300 audio feature derived from the DT 770 is the absolutely amazing clarity and precise detail of the high frequencies. Sounds sparkle and dance with a quickness hard to find in many ‘audiophile’ headphones. We were even able to detect compression and distortion artifacts present in game soundtracks during cut scenes, explosions or voice acting due to the incredible resolution of the MMX 300. The highs extend to the point they can maybe become a touch bright and even slightly grainy in the highest uppermost frequencies depending on the imbedded game sound quality. Midrange response remains decent, but may be a bit lacking in this gamer headset as it doesn’t have great warmth in the vocals and some gunfire can sound a bit thin on occassion. However, this quibble should not be completely discouraging or a total deal-breaker for hard-core gamers. The bass of the MMX 300 sounds tight and punchy with accurate texture and detail. It certainly doesn’t boom or overwhelm the audio like most gaming headsets. In fact, we found the bass perhaps a bit lean during giant fireball explosions. However, there is debate among gamers that too much bass response can be distracting or confusing in fast-paced online FPS (First Person Shooter) gaming. Our HeadRoom conclusion is this gamer headset nails bass quite well; not too boomy, not too thin, just right.

The condenser Beyerdynamic-patented microphone on this headset is also ‘professional’ grade. The voice chat transmission quality is crystal clear and highly intelligible and the adjustability of the mic boom is nearly infinite, so you can always place it exactly where you need to avoid dreaded “heavy breathing into the mic” syndrome. For PS3 users, the USB device has a handy mute button to kill your chat at any time. We do feel the Beyerdynamic MMX 300 headphone benefits significantly from extra amplification. Used directly out of computers, the sound can be dry, tonally flat, and vanilla boring; it just doesn’t muster quite the same quickness and authoritative punch without being powered via a dedicated headphone amp. Overall, it’s hard to beat this combination of terrific sound quality and wide, spacious soundstage image especially considering this is a sealed-back headphone design. By the way you can use the MMX 300 to listen to your favorite music too. So if you are serious about gaming and serious about the absolute best sound quality in the category, the Beyerdynamic MMX 300 is one of the few gamer headphones worth its high price tag.


If buying the Beyerdynamic MMX 300 headset for use with Sony PS3 or Xbox 360, prepare to be slightly disappointed. Plugging the supplied USB device into your PS3 -- or the headphone outputs into your Xbox controller -- will only provide the voice chat of other online players. It does NOT send the game soundtrack audio to the headphones. They only way to hear the actual game audio is to use a headphone amp and the composite (red/white) audio output from your console. Or the better option is to use the optical output of your console to a DAC/headphone amp for the best sound quality. Some hardcore gamers take things even further and add a second headphone amp to combine the chat audio into the game audio for the very best seamless audio experience!

Awesome gaming headphones !
Posted by hehe2 from Paris, FRANCE on 2012-08-23

Recommend Product: Yes
Pros: Pure quality sound, PS3 compatible (read how-to)
Cons: Can feel a bit "too tight" on the head after one or two hours of use...

Well, I purchased this headset some months ago and I can truly tell you that the sound quality is the best you can get at this price range (to be honest, Beyerdynamic has some exact same models without the microphone for about three times the price...).

So, pure audiophiles : don't hesitate, you have there REALLY good headphones.

For gamers, this headset is just awesome. It has to be used (I'm a PC and PS3 owner only) with the provided "USB sound card" though, otherwise your integrated sound card input/output (for computers) won't provide you the best sound quality, lacking of power...

So, plug the provided USB sound card and plug the "heaset" on it, "et voilĂ ", you got it !

For PS3 users, you should be "angry" at the start because it's considered as a "headset" and thus the PS3 acts as it was one : only the "voice chat" sound is directed through the headphones, the game sound is using the regular sound output (most of the time, your speakers).

Don't panic ! You just can configure this ! Go to "settings => Accessories => USB microphone" and set it to go through your regular output device.

Now, go to your settings => audio and set your output to your USB device and that's it, you got everything routed through your headphones.

Note : for the best experience and the most exigent users, use it combined with a "astro Mixamp pro" (or some equivalent device) and you'll have the ultimate gaming headset. It will provide you with a direct access to the volume via a giant knob plus you can mix an external source like a mp3 player alongside the game sound, plus use your PS3 digital optical sound output for best quality... very handy =)

Pros :

- sound quality (really accurate mid/high tones, deep basses, studio quality sound)
- microphone quality (ultra clear voice)
- durability (seems solid)
- design (I got the "gray" ear cushions + "carbon style" version and it looks awesome =)

Cons :

- can feel a bit "too tight" after one or two consecutive hours of use

Personal rating : 4.5/5

Recommend Product: Yes
Pros: Comfortable, Great Sound, Amazing Mic
Cons: Dated Style

(Once again, I forgot that these reviews remove returns. I will double dash -- where paragraph breaks should be to help isolate my comments. I wish they'd fix that.)

I've had these a good while now and feel I am qualified to speak to the MMX 300 strengths and weaknesses.

-- I was tired of $50 headsets that made my ears hurt by sitting on them or being too shrill or just plain too loud in a very narrow band. I'd learned the benefits of clean amplification, even with inexpensive headphones and was tired of mics that either made me sound like a little girl or worse, only picked me up when I was screaming.

-- After spending a lot of time researching, I realized that not only could I use them for gaming but I could use them at work. Given the sealed cups, there is good isolation from general noise - and it also helps keep my music inside my head where it belongs. Sometimes other people's leakage can be annoying. So you would be right thinking that I wear these for hours at a time. I spend even more time with them on when I game over the weekend, the velour earpads are amazing. Neither cold nor hot. Not slick or sweaty they really fell good and continue to look as good as the day they came.

-- I looked for a relatively flat frequency response over a wide range to ensure that I thought I was getting a fair representation of what the audio should sound like. Do you know what the one audio problem I found was? Source. I found many motherboards have horrible isolation issues and these darned headphones showed me just how bad it can be. On some PCs I could actually hear the mice on nearby USB ports and on my desktop at home with Intel's HD Audio, there is just a slight ring that gets picked up and it is annoying. It all comes down to source - and I don't blame the headphones for it, it is just that they let me hear it where other headphones don't.

-- The included USB adapter is good and sounds clean. It's not your cheapo $10 USB "sound card" that just wraps a stock chip with whatever audio components they could get today. It's properly engineered to sound decent. It has only two flaws. Input is monaural so it's not a line-in replacement and output just really doesn't have the power to do these headphones justice.

-- Solution: a Total Bithead.

-- This solved all my signal quality issues I had with onboard audio (hoping that the promise of 192kbit audio really was there - it's not.) and power. It works with every machine I hooked it up to and flexible power options means I could use any USB port as a power jack to listen to my iPod. Even though the dac doesn't have fantastic numbers, the whole unit sounds great plugged into anything with these headphones.

-- Yes, that does change the pricing a bit but honestly, if you're going to spend this much on headphones buy a decent source to drive them with.

-- These things sound so good the guys at work would steal them if they weren't so distinctive looking. That is not really a good thing. They just haven't got much style and they look a bit dated. But put them on and "who cares" what they look like when they sound this good.

-- The only headphones I would listen to before these are my DT990s.

soso for price.
Posted by musicmonkey from CA. on 2012-03-25

Recommend Product: No
Pros: look nice, usb interface
Cons: average sound, heavy, ears sweat

I hooked these cans up to my x-fi titanium sound card and they sound no better than a 50 dollar pair of phones. Sound is ok but not worth 400 bucks for sure. They are heavy and make my ears sweat.
It said on their website ( Beyerdynamic site ) that they were supposed to be high quality for music and gaming. Maybe for gaming but definately not music.
I'll continue to write this honest opinion i have of them until Amazon and the Recording store give me a refund. But that's a whole other story :/
