MMX 300 PRO: Detailed Game Audio, Clear Communication
The beyerdynamic MMX 300 PRO combines STELLAR.45 drivers with a cardioid condenser boom microphone in a closed-back wired headset. It suits players who want an analogue audio path, precise game detail and a comfortable fit without a charging routine.
This is the 48-ohm PRO model. Its revised headband and driver system distinguish it from the earlier MMX 300 generations.

Explore the Features

FEATURE 01
STELLAR.45 Gaming Audio
The driver platform comes from beyerdynamic’s studio range and is tuned here for games. It reproduces the changing layers of a game soundtrack alongside dialogue and directional effects.

FEATURE 02
Closed Earcups for Focus
The closed design reduces some external distractions and playback leakage. Passive isolation depends on pad fit and does not make the headset an active noise-cancelling model.

FEATURE 03
A Condenser Microphone for Team Chat
The cardioid boom microphone covers 20Hz–20kHz. Position it close to the corner of your mouth and set gain carefully for clear speech without breath blasts.
FEATURE 04
48 Ohms for Practical Source Matching
The 48-ohm STELLAR.45 system is designed for use with common gaming sources. A suitable headset output can power listening while its microphone input handles chat.

FEATURE 05
PC and Controller Connections
The analogue cable ends in separate 3.5mm plugs for audio and microphone. The included Y adapter supports a compatible combined headset socket on a console controller.

FEATURE 06
Comfortable Velour Ear Pads
Soft velour surrounds the ears and helps make extended sessions comfortable. Keep the pads clean and replace worn pads to maintain a consistent fit.

FEATURE 07
A Headband Designed to Reduce Pressure
The padded headband includes a central recess and a practical fastener. The spring-steel core supports the fit without making the padding a permanent, non-serviceable component.
FEATURE 08
Replaceable Wear Parts
Pads, headband and cable can be replaced. That makes routine maintenance possible when a heavily used gaming headset needs attention.

FEATURE 09
German-Made Construction
The MMX 300 PRO is made in Germany. Its combination of durable materials and serviceable parts is useful for a setup you intend to keep through multiple PC upgrades.
Set Up Sound and Voice Separately
Connect both PC plugs to the correct headphone and microphone ports, or use the supplied Y adapter with a compatible combined headset socket. Select the correct input and output in the game or voice-chat application.
This is an analogue headset. A USB-only console port needs a compatible audio interface; a passive USB adapter does not automatically provide console support.
Compare Your Gaming Audio Setup
For simpler wired alternatives, compare MMX 100 Black and MMX 150 USB. The latter’s Augmented Mode is a separate USB feature, not part of MMX 300 PRO.
If you prefer separate headphones and a desk microphone, see DT 700 PRO X and RODE PodMic USB.
Frequently Asked Questions
Is this the MMX 300 PRO or the second generation?
This is the PRO model with 48-ohm STELLAR.45 drivers, the updated headband and a condenser microphone.
Is it wireless?
No. The MMX 300 PRO uses a wired analogue connection.
Can I use it with PS5 or Xbox?
Yes, through a compatible 3.5mm headset socket using the included Y adapter.
Does it have USB Augmented Mode?
No. That feature belongs to the wired MMX 150, not this model.
What is the microphone type?
It is a cardioid back-electret condenser boom microphone with a 20Hz–20kHz frequency response.
Does it need 48V phantom power?
No. Use a compatible headset microphone input. Do not connect the headset microphone directly to a 48V XLR phantom-power supply.
Can I replace the cable and pads?
Yes. The cable, ear pads and headband are supported as replaceable components.
