Plug the provided USB-C to 3.5mm cable into headphone audio input to engage
passive (wired) audio. Headphones are required to be powered on for audio
to work.


Activate Pairing Mode by powering ON the MG20 and continuing to hold the
button until the ring pulses and the pairing tone is heard. Access the Bluetooth menu on your device and select M&D MG20.


Up to two devices can be connected to the MG20 at one time, including the
Low-Latency Adapter. If two devices other than the Low-Latency Adapter are
connected to the MG20, the MG20 will need to be put back in pairing mode in
order to reconnect to the Low-Latency Adapter.


Plug the adapter into a PC or Playstation and power on the MG20. If no
connection is made:

  1. Unplug the adapter.
  2. Put the MG20 into pairing mode.
  3. Ensure your PC or Playstation is powered ON.
  4. Plug the adapter back in.


Press and hold button to power ON/OFF. Battery level will be displayed at
startup. To conserve power, the MG20 will enter sleep mode after 10 minutes
of not being worn.

Our ability to hear is amazing. Treat your ears like the precious tools they
are, and they will continue to provide you with exceptional data, as well as a
lifetime of incredible sonic experiences.

In general, do not listen “too loud” or for “too long,” and be attentive to your
own ears. Ringing, discomfort, or sensitivity to high frequencies and treble
may be a signal from your ears that you are pushing them to their limits and
causing irreparable damage.

As a general practice, find what seems to be your preferred listening level
and then adjust the volume down another 10% or more. Surprisingly, your
ears will attune to a slightly lower volume over time, and what seems quiet
at first can be perfect for longer listening periods.


NIHL is a preventable condition caused by both one-time and extended
exposure to excessive decibel (dB) levels. This harm to sensitive inner ear
structures is irreversible and people of all ages can be affected. Damage
can happen in a single event or gradually over time. One-time exposure to
an intense “impulse” sound, such as an explosion, or by continued exposure
to loud sounds over 85 decibels can cause harm. Indicators of NIHL include
hearing loss and tinnitus, a condition of sensing constant ringing, buzzing, or
roaring. The NIDCD (National Institute on Deafness and Other Communication
Disorders) offers this simple rule of thumb: avoid sound exposure that is
“too loud, too close, or too long.” Here are some general references to sound
levels that occur in everyday life: refrigerator humming (45 dB); normal
conversation (60 dB); city traffic (85 dB); motorcycles (95 dB); an MP3 player
at full volume (105 dB); sirens (120 dB); firecrackers (150 dB).
