FIT
Your earphones come with the medium silicone ear tips attached.
Choose the ear tips that form a seal with your ear canal. Our custom round ear
tips are designed in conjunction with the oval nozzle shape to provide a
superior universal fit. Squeeze the ear tip to match its orientation to the
nozzle and then press the ear tip against the nozzle to attach. Tip: to
ensure a secure fit, download the M&D Connect App and perform a Fit Test.
To insert your silicone ear tips, follow these steps:
STEP 1: Tilt the earphone forward with the ear tip resting lightly in your ear
canal.
STEP 2: Rotate the earphone down until the ear tip forms a seal with your ear
canal.
To insert your earphones using foam ear tips:
STEP 1: Gently compress the foam ear tip using your fingers.
STEP 2: Insert it into your ear.
STEP 3: Hold the earphones in place until the foam fully expands and forms a
seal with your ear canal.

CHARGING
Your earphones hold up to 16 hours of charge. The charging case holds an
additional 32 hours of charge for your earphones. We suggest you place your
earphones inside the case when they are not in use. This will allow them to
have the maximum charge each time you begin to use them.
Your earphones will arrive with the battery partially charged. The battery
status will be displayed when opening /closing the lid. A green light
indicates the battery is between 70-100%, amber indicates 30-69%, and red
indicates 1-29%. If the center battery flashes red or does not display, the
case battery is depleted.
To charge your case, plug in the USB-C cable into the right side of your case
and plug the other end into a power source.
To charge your case via wireless charging, center your MW09 charging case on
any compatible wireless charging pad with the LEDs facing upwards. The MW09 is
also compatible with MC100 and MC300 Wireless Charge Pads (sold separately).
CHARGING
The battery status of the case and earphones will remain visible while the case charges.
- Case and earphones charge to 50% in 20 minutes, 100% in 60 minutes via included charging cable
- Case charges to 50% in 20 minutes, 100% in 60 minutes via included charging cable
- Case charges to 50% in 30 minutes, 100% in 110 minutes via wireless charging
- Case and earphones charge to 100% in 160 minutes via wireless charging
MAINTENANCE
Over time the proximity sensor that helps regulate pause/play functions may
become dirty and affect performance. If this happens, take a damp
Q-tip or damp cloth and lightly rub the sensor.
To clean the earphones, use a microfiber cloth. Do not use alcohol or other
cleaning substances on the product. Do not drop, sit on, or allow the
earphones to be exposed to water, moisture, or temperature extremes.
Your earphones are IP54 water resistance rated. Your charging case is IPX4
rated.
It is recommended that you return your earphones to their storage case when
not in use. Always return your earphones to their charging case within 72
hours to minimize potential battery life degradation.

TROUBLESHOOTING
TROUBLE PAIRING EARPHONES AND
SOURCE DEVICE
Make sure both earphones are outside the charging case when attempting to pair
your device. Cycle power by placing earphones in the charging case and fully
closing the lid for 10 seconds. Then remove the earphones from the case to
verify they have entered pairing mode. The indicator light will slowly pulse
on the right earphone.
- Turn Bluetooth OFF, then ON again on the source device.
- Turn OFF Bluetooth feature on any other device that is paired with the earphones.
- Delete any “M&D MW09” earphone connections from your device and then put your earphones into pairing mode and pair again.
- Make sure “M&D MW09” is selected in the Bluetooth device list.
TROUBLE CONNECTING EARPHONES TO THE M&D CONNECT APP
- Ensure the earphones are connected in your phone’s Bluetooth menu prior to using in the app.
- Close and reopen M&D Connect.
- Update M&D Connect to the latest version in the app store.
- Update your phone to the latest OS.
- Disconnect from any other devices that the earphones are connected to via multipoint.
BATTERY LEVEL INDICATORS ON CHARGING CASE ARE NOT LIGHTING UP
Make sure your case is charged. To charge the case, plug one end of the USB-C
cable into the back of the case and plug the other end into a power source.
Try using a diffrerent power adapter or charging cable if issues persist.
Make sure the earphones are properly placed inside the charging case.
“L” represents placement for the left earphone and “R” for the right earphone.
Make sure the charging pads on the earphones and charging pins in the case are
clean, and that there is no other debris in the case. Use a damp Q-tip or damp
cloth to lightly rub the charging pads and pins.
NOTE: If the charging case battery is depleted, the indicator lights will
not light up to show your battery level status when earphones are inserted
even if the earphones still have battery life.
PLAY/PAUSE NOT WORKING WHEN PLACING IN AND REMOVING FROM EAR
Over time the proximity sensor that helps regulate pause/play functions may
become dirty and affect performance. If this happens, take a damp Q-tip or
damp cloth and lightly rub the sensor.
NO AUDIO OR POOR AUDIO QUALITY FROM A CONNECTED BLUETOOTH DEVICE
Move the source device closer to the earphones, as physical objects between
the earphones and the source may obstruct the signal.
Try another music application or try another track. Try a different source
device.
FACTORY RESET
If your earphones are no longer paired to each other, please use the following
steps to perform a factory reset:
- Remove the Left earphone from the case (Leave the Right earphone in the case).
- Quickly press VOL+ on the Left earphone 6 times, and hold on the 6th press until you hear the voice prompt announce “factory reset” on the Left earphone.
- Remove the Right earphone from the case.
- Quickly press the Multi-Function button on the Right earphone 6 times, and hold on the 6th press until you hear the voice prompt announce “factory reset” on the Right earphone.
- Put both earphones next to each other. The earphones are paired to each other when the LEDs stop flashing and start “breathing” as they usually would when pairing to a Bluetooth device.
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).
