EAR TIP OPTIONS
XS S M
L XL
Your earphones come with medium 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. If you have difficulty attaching the ear tip, try squeezing
the ear tip to match its orientation to the nozzle and then press the ear tip
against the nozzle to attach.
To insert your earphones follow these steps:
STEP 2: Rotate the earphone down
until the ear tip forms a seal with
your ear canal.
STEP 1: Tilt the earphone forward
with the ear tip resting lightly in your
ear canal.

Your earphones hold up to 12 hours of charge. The charging case holds an
additional 30 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. If you do not have a USB-C power
source you can use our supplied USB-C to USB-A adapter to use a USB-A
power source.
The battery status of the case and earphones will remain visible while the
case charges.

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.

Master & Dynamic guarantees this product against defects in materials or
workmanship for a period of two years from the date of original purchase on
our website or from an authorized Master & Dynamic retailer or reseller. As
an exception to this warranty period, batteries are guaranteed for proper
functioning for a period of one year from the date of original purchase.
Defective batteries are covered by Master & Dynamic’s Limited Warranty but
battery wear from normal use is not covered.
If returned within the warranty period, Master & Dynamic will at its discretion
either repair the defective product or replace it with a repaired or refurbished
product of identical specifications as the returned product. This limited
warranty is in lieu of all other warranties, expressed or implied, including,
but not limited to, any implied warranty of merchantability or fitness for a
particular purpose.
Master & Dynamic shall have no liability of any kind for any direct, indirect,
incidental or consequential damages or expenses that arise from the use of
this product.
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).
NIHL WARRANTY

Master & Dynamic’s Limited Warranty does not cover normal wear and tear to
items such as blown drivers, battery degradation from normal use, cut cords,
bent jacks, loss or theft. Replaceable parts subject to wear and tear such as
ear tips and cables will be replaced only in case of malfunctioning due to
material or manufacturing defects, and only once during the warranty period
of your product.
The serial number and proof of purchase are required in order to enact the
warranty for products purchased on our website or from an authorized
retailer or reseller. This policy is also applicable to products received as a gift.
If we need to replace your earphones due to a battery defect, your earphones
will be new or equivalent to new in performance and reliability. You will void
your warranty if you disassemble your earphones or expose them to excessive
moisture. If you believe your product is defective within the warranty period,
please contact us at [email protected]. Please include your
product’s serial number, proof of purchase, telephone number and full return
shipping address in your message to us. Conditional to serial number, proof of
purchase, and warranty validity, you will be issued a return authorization and

ment product will take place after our receipt of the defective product. For
