PAIRING / CONNECT TO A BLUETOOTH DEVICE

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 MG2

MULTIPOINT

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.

LOW-LATENCY ADAPTER

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

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

POWERING ON/OFF

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.

The headphones can be used while charging.

Power OFF Headphones
Turn headphones on and headphones will automatically connect to device 1 and 2 simultaneously.

Do not drop, sit on, or allow the headphones to be exposed to water, moisture, or extreme temperature.

MAINTENANCE + TROUBLESHOOTING

THE HEADPHONES AND DEVICE WILL NOT PAIR:

Make sure the headphones are charged. Cycle power switch OFF and ON.
Turn the Bluetooth OFF, then ON again on the source device.
Turn Off the Bluetooth feature on any other device that is paired with the headphones.
Hold power button down for 5 seconds to enter pairing mode.
Make sure “M&D MG20” is selected in the Bluetooth device list.

NO AUDIO OR POOR AUDIO QUALITY FROM A CONNECTED BLUETOOTH DEVICE:

Move the device closer to the headphones, as physical objects between the headphone and the source may obstruct the signal.
Try another music application or try another track.
Try a different audio device.
Disconnect from multipoint and use with only one device at a time.

FACTORY RESET

Power Off the headphones. Hold power button for 5 seconds to enter pairing mode. Simultaneously hold multi-function button and power button until LED lights flash red/white. LED light will flash 4x. The headphones will then be reset.

EAR HEALTH

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

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).
