USER MANUAL — MH30 ON EAR HEADPHONES

SOUND TOOLS FOR CREATIVE MINDS
Our obsession is the interaction between sound and creativity.
Our passion is building beautifully designed, technically
sophisticated sound tools for creative minds.
Our MH30 On Ear Headphones are designed to be a more mobile
thinking cap, part of the everyday creative toolkit for those
whose workspace is ever-changing and fluid.
DESIGNED FOR DECADES OF USE
Our headphones are designed to be an essential part of your everyday
creative toolkit that can stand up to decades of use. They are built with
the creative workspace in mind, yet with added portability.
Our headphones are constructed of a forged aluminum body, and utilize
stainless steel components in all high strain areas, including the foldable
hinges. Areas subject to heavy wear, such as cables and ear pads, are
built to last and can be easily replaced as needed. All metals are anodized
or PVD coated, not painted. We separated the microphone from the
remote for increased vocal clarity and reduced noise, removing the need
to hold the remote while you speak on the phone.
APPOINTED WITH THE FINEST MATERIALS
Our headbands are constructed with a premium grain cowhide on
the exterior surface and lined with a soft lambskin. The ear pads
are memory foam, wrapped in lambskin, providing superior comfort
and breathability.
Our heavy-duty woven cables utilize oxygen-free copper to ensure
pure sound and reduced noise. All headphones include a genuine
leather box to store your extra cables and accessories, as well as
a canvas carrying case with a soft interior lining.
A RICH, WARM SOUND
We sought a rich, warm sound signature from our custom 40mm
neodymium drivers. An expansive soundscape that perfectly
captures the exceptional detail that well recorded music has to
offer. Our tuning is designed to accommodate a diversity of tastes
and musical genres.

MAINTENANCE AND TROUBLESHOOTING
Clean ear pads and headphones
with soft, slightly damp cloth.
Do not soak, submerge or allow
moisture to enter near the
drivers or cable jacks. Ear pads
and cables can be purchased
if they are worn out at:
www.masterdynamic.com
Do not drop, sit on, or allow
the headphones to be exposed
to water, moisture, or
temperature extremes.
It is recommended that you
return your headphones to
their storage case when not
in use. To avoid damage, do
not store other items in the
canvas case along with your
headphones.
CAUTION: Incorrectly rotating
or over rotating the earcups
can damage the headphones.
No Sound:
•
Check to make sure all plugs
are fitted completely into their
jacks, both in the headphones
and at the audio source.
•
Check source device to make
sure sound is coming out.
•
Check cable for signs of
extreme wear or test another
cable to see if cable is damaged.
Remote not working:
•
Check to ensure that source
plug is inserted into audio
device and headphone plug is
inserted into earcup.
HEARING HEALTH AND FITNESS
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 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.
If your co-workers (3 – 10 feet away) are always singing along or
commenting on your music choices, chances are good you may be
listening too loud. See an audiologist to have your hearing tested.
If you are interested in tuning your ear to have a more refined
sonic palate, there are some apps and training programs you can
find online.
PREVENTION OF NIHL (NOISE INDUCED HEARING LOSS)
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 sounds louder than 110 decibels
and extended exposure to 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).
