Thank you for selecting the MMX 300 headset. Please take some time to read
carefully through this quick start guide before using the headset.
Safety Instructions
Warnin : When connecting the headphones, make sure that you have turned
the volume down to the minimum. Adjust the volume only after the
headphones are in place.
We would like to point out that listening at high volumes over a long
period of time may damage your hearing irreversibly.
Make sure that the set volume is not too high. Rule of thumb: The
higher the volume, the shorter the time of listening. This also shows
an example from working life: According to the Occupational Health
and Safety Regulations of German trade associations, noise
pollution e.g. in the workplace must not exceed 85 dB (room
volume level) during a maximum permissible listening time of
8 hours. If the volume level is increased by 3 dB respectively, the
permissible listening time is cut in half, i.e. at 88 dB, the listening
time is 4 hours, at 91 dB 2 hours, etc.
Risk of injury!
When wearing wired headphones, avoid any sudden movements. You could
seriously injure yourself, especially if you have any piercings or wear earrings or
glasses, etc. that can get caught in the wire.
Warnin – Microphone
Please make sure that you do not connect the microphone to microphone inputs
supplying phantom power (12 - 48 V), as this will damage the microphone.
Applications
The MMX 300 is an ideal headset for all gaming, multimedia and Voice over IP
applications. The technology of the MMX 300 is based on the reliable HS 400
aviation headset suitable for hi-fi applications. The noise-cancelling microphone
with a crystal-clear sound ensures a clear and precise voice transmission even in
noisy surroundings. The closed design guarantees absolute undisturbed enjoy-
ment of game and sound combined with a high comfort due to soft, replaceable
ear and headband pads.
Thanks to the cable remote control and supplied adapter cable the MMX 300
headset is suitable for use with a PC and gaming with a notebook or console
which have a mini (3.5 mm) combination jack.

Settin up and Use of the Headset
Put the headset on your head. The microphone is on the left side. Position the
microphone to the front of the middle of the mouth. In order to avoid pop noise
you should use the microphone with a pop shield.
Headband
For best comfort and noise attenuation, the headband can be adjusted to fit
your head properly.
Wear the headset so that the headband runs over the top of your head and
adjust the headband so that
• your ears are completely enclosed by the ear cushions,
• you feel a gentle pressure around your ears,
• both ends of the headband have the same length to ensure a proper fit
Microphone
• The pop shield should enclose the microphone completely.
• Bend the flexible gooseneck so that the microphone is placed about 2 cm in
front of the middle of your mouth.
Important: In order to avoid overstretching and premature wear and tear
never bend the gooseneck more than 90°.

• Turn the microphone holder (not the
gooseneck!) to position the micro-
phone as requested.
Connection
The MMX 300 headset is supplied
with two connecting cables.
Headset cable with a 4-pole jack
connector to connect to tablets,
smartphones and laptops.

Headset cable for gaming sessions
with two 3-pole jack connectors to
connect to a headphone output and
microphone input of a PC, notebook
or console, which have a mini
(3.5 mm) combination jack. Due to
the screwed-on adapter the head-
phone can also be connected to
devices with a 1/4" jack.
Note:
A common source of error is that the 5-pole jack connector is not properly
connected to the headset. If the headset does not work, please check first
whether the cable is completely plugged into the headphone housing of the
MMX 300. Please refer also to fig. 1.
There is a locking protection on the 5-pole jack connector of the connecting
cable, which has to lock in place. When a malfunction occurs, simply pull out
the plug again and push it firmly into the socket with a slight rotary motion so
that all 5 poles of the connector have contact. Please refer also to fig. 2.

Maintenance
• As with any equipment which will be used in close proximity to sensitive areas
of the body, it is essential that the ear pads and headband are kept clean. Use
a damp cloth for cleaning using warm water only taking care not to allow any
water drops into the transducers.
• For cleaning the pop shield remove it from the microphone and wash it
under clear running water. If necessary you can use a mild cleansing agent
(e.g. washing-up liquid). Make sure that the pop shield is completely dry
before you replace it onto the microphone.

Chan in the Headband Pad
1. Open the Velcro and remove the padding from the headband. Take care not to
damage the cable.
2. Place the new opened headband pad on the underside of the headband.
Make sure to lay the cable in the crease of the pad on the outer edge of the
band. Tip: to do this, splay the headphones slightly, over both knees, for
example.
3. First close the middle Velcro fastening and the two outer ones.
How to replace the Ear Pads
• Should it become necessary, replace the
ear pads.
• Pull the ear pads up and remove them
from the earcups. The new ear pads can
be attached easier, if you warm them
beforehand.
• If other components have to be replaced,
please contact your beyerdynamic dealer.
Service
Servicing must be carried out by qualified service personnel only. Dismantling
the headset yourself will invalidate the guarantee.
