Studio DNA for an immersive gaming experience
At the heart of the MMX 300 PRO is the STELLAR.45 driver, which is also used in the Beyerdynamic DT 700 Pro X and DT 900 Pro X studio headphones. This ensures the exceptional audio fidelity and spatial sound reproduction of the MMX 300 PRO. Compared to the previous model, the bass and treble profiles have been thoroughly refined. Acoustic in-game events can be pinpointed immediately. The MMX 300 PRO is also impressive when it comes to music playback.
The integrated condenser microphone provides a competitive edge thanks to high speech intelligibility.
