beyerdynamic MMX 300 PRO review

The beyerdynamic MMX 300 PRO is a wired headset for players who care more about audio fidelity than features. beyerdynamic fits the STELLAR.45 driver it also uses in studio headphones, with a published headphone frequency response of 5 to 40,000 Hz and a 48 ohm impedance that the company says works on PC and consoles. The microphone is a cardioid back electret condenser. Connection is two 3.5 mm jack plugs, with a Y adapter for consoles; beyerdynamic lists support for PS5, PS4, Xbox, Nintendo Switch and other consoles with 3.5 mm. Comfort is the other draw: velour pads, a head pad with a fontanelle recess and a weight of 314 g without the cable. At $379.99 on the check date, it is the priciest headset here, and it has no wireless, no USB and no surround processing. We compared documented features and published prices only.
