Bring studio sound to your games

The MMX 300 PRO uses Beyerdynamic's STELLAR.45 driver, bringing technology also found in its studio headphones into your gaming setup. Dedicated gaming tuning balances the highs, mids, and lows, providing detailed reproduction across different game situations. Precise sound localisation helps you identify smaller audio cues and judge their position, while the low end gives atmospheric music added depth.

Refined higher frequencies also make the headset suited to listening to music outside gaming. Its closed-back construction helps reduce surrounding distractions, allowing you to concentrate on these details. With a 48-ohm impedance, the driver can perform across PCs and compatible consoles without requiring a dedicated amplifier.

Make every call easy to understand

Clear communication matters when you need to share information quickly with your team. The MMX 300 PRO uses an integrated condenser microphone designed around Beyerdynamic's microphone experience, providing natural voice transmission during games and voice chat. Its extended 20 Hz to 20,000 Hz frequency range reproduces both high and low frequencies with detail, helping your voice remain clear and balanced.

A supplied foam pop filter provides an additional practical accessory for the microphone. Combined with the headset's detailed sound reproduction, this gives you clear communication in both directions, helping you hear important team calls while making your own instructions easy for other players to understand.

Stay comfortable through longer sessions

Extended gaming sessions put comfort high on the list, so the MMX 300 PRO borrows ergonomic features from Beyerdynamic's studio headphones. Soft velour ear pads provide comfortable contact around your ears, while the redesigned headband includes a dedicated fontanelle recess to reduce pressure on the top of your head.

A snap-button closure on the head pad adds further practicality to the design. Together, these features are intended to keep the headset comfortable during long periods of play. The closed-back ear cups also provide passive isolation from surrounding sound, helping you remain focused on your game without relying on electronic noise cancellation.

Built for years of gaming

Made in Germany, the MMX 300 PRO combines careful construction with materials selected for repeated use. A spring steel headband core provides a sturdy foundation, while key wear components can be replaced instead of requiring you to change the complete headset. Replacement ear pads, headband parts, and cables are available to help keep it working over time.

The supplied 2.5-metre detachable cable gives you useful reach around your setup, while the included Y-adapter supports use across PC, PlayStation, Xbox, and Nintendo Switch systems. You can also personalise selected visual elements through Beyerdynamic's MANUFAKTUR service for a more individual setup.
