Beyerdynamic MMX 300 (2nd gen.) Review

What is good for a pilot will probably also be good enough for a gamer, maybe not? We checked the headset, which has been extremely popular in the target group, to determine whether its popularity is justified or based on good marketing. What findings does our test provide?


  • Excellent headphone sound for gaming and multimedia applications
  • Good sound quality of the microphone
  • High quality build
  • Good fit and comfort, practical operation and mute (microphone) via remote
  • Appropriate scope of delivery
  • Fair price


  • Headphone height presence is not for everyone

Details & practice

Features and product properties
The backbone of the Beyerdynamic MMX 300 headset are closed headphones with circumaural auricles and dynamic sound transducers, whose housing construction corresponds to Beyerdynamics’ classic studio headphones that have been tried and tested for decades. “Proven,” among other things, because the fit and comfort, both of which are fundamentally important product properties, are highly valued by many users, including myself. This applies in particular to the generously dimensioned and exemplary soft velour ear cushions, which in my opinion, are among the most comfortable on the market. The earpads and the headband pad are, of course, interchangeable. The swiveling gooseneck of the condenser microphone (back electret) is attached in the center of the left auricle. In the lower area, there is a mini-jack socket for cable connection. The scope of delivery includes two cables, each with a remote (mic mute, volume, telephony, and playback functions). Still, different cable ends (see illustration) for connection to computers and tablets/smartphones. The headset flawlessly made in Germany is supplied in a practical hard case for storage and transport.

Purpose of use

Beyerdynamic already has various headset models for professional broadcasting and communication applications. The Beyerdynamic MMX 300 headset fills the remaining gap for gaming, multimedia, and smartphone/tablet use, which does not necessarily have to exclude properties suitable for profit (insulation, audio quality, robustness) and must not exclude, as it is professional some gamers demand a lot from their equipment. Therefore, the Beyerdynamic headset should easily meet all conceivable requirements.


The scope of delivery includes a Y-cable with a three-pin mini-jack plug for connecting to the microphone input of a computer and a stereo jack connection (3.5 mm including an adapter to 6.35 mm) for the headphone socket. The second cable with its four-pin mini-jack plug is suitable for connection to smartphones and tablets such as my iPad, which was used to record the audio samples.

Sound Quality

In previous test reports, I already wrote that the typical sound signature of Beyerdynamic headphones often does not correspond to my subjective preferences when it comes to the implementation of sound-critical measures. The powerful and bass-strong “larger-than-life playback” fits the Beyerdynamic MMX 300’s special field of application like a fist on the eye. In addition, the sense of space and the location are lively and precise, which is a decisive factor in gaming, for example. On the other hand, only the sometimes somewhat unyielding reproduction of the high frequencies tends, in my opinion, a little too quickly to the sharpness of sibilants and other mix elements in this frequency range.

Sound of the microphone

The homogeneous sound quality of the voice recordings, which were created with the back electret condenser microphone of the Beyerdynamic MMX 300 (2nd generation), I find extremely successful in direct comparison with the professional broadcast headsets I know. The speech intelligibility easily meets professional requirements, and the frequency response is very balanced and sounds neither too thin nor too thick in the low frequencies. Problematic close-up artifacts are virtually non-existent, and the sensitivity to loud ambient noises and structure-borne noise caused by touching the cable is pleasantly low. Top!


With the 2nd generation MMX 300 headset from Beyerdynamic, you get a sophisticated gaming/multimedia headset at a reasonable street retail price. The production quality of the headphone/speaker combination made in Germany is excellent. The sound properties, both of the microphone and the headphones, are of a very high level and, in most cases, should meet the requirements and preferences of the target group. Only the sometimes somewhat unyielding height mapping, a characteristic feature of various headphone models from Heilbronn, is known not to suit everyone’s taste. Therefore, it is worth checking whether the MMX-300 headset meets your own needs!
