Thank you for your purchase of a HIFIMAN product. We take great pride in
offering audio products that provide best-in-class performance and value.
Though it seems like only yesterday when, as a passionate audiophile, I started
HIFIMAN, we just finished our first decade in business and eagerly look
forward to an exciting future. The company continues to grow at a rapid pace,
and the HIFIMAN brand is one of the most respected in the industry.
Even with our success, two things that never change are my love of music and
my commitment to creating products that recreate the experience of hearing
a live performance. I am joined by many others in the company who share my
passion and in turn, we humbly share our passion with you.
Thank you again for your purchase. I hope you will find this guide a useful tool
for learning about your product, ultimately helping you enjoy countless hours
of pleasure.
Happy listening,

A smaller mass from either the diaphragm or conductor results
in improved upper frequency response.
Outstanding Sound Quality
Compared to traditional dynamic headphones, planar magnetic
technology offers a superior sounding experience in terms of overall
quality, especially when it comes to the aural soundstage. Dynamic
headphones utilize conductors that vibrate in select areas of the
diaphragm. This results in a large percentage of the diaphragm not
being directly driven by those conductors, resulting in somewhat
diminished performance. Planar magnetic headphones are funda-
mentally different in that their weight (conductors + diaphragm) is
much lower than dynamic headphones. The result is superior perfor-
mance, especially in the upper frequencies, or treble.

Planar headphones feature conductive layers distributed throughout the
surface of diaphragm. The diaphragm is evenly driven by the magnetic force
so that planar headphones produce significantly lower distortion when
compared with conventional dynamic headphones.
This lower distortion results in better overall reproduction of minute details.
Positioning of instruments and other elements of imaging are demonstrably
better, with a soundstage that is consistently wide and natural sounding.

The advanced magnet design featured in the DEVA Pro is acousti-
cally transparent, dramatically reducing wave diffraction turbulence
that typically degrades the integrity of the sound waves. The result
is reduced distortion, yielding a purer, more harmonious sound that
is demonstrably better than previous designs.

DEVA Pro DEVA Pro

HIIMAN devoted extensive time and resources to create a nano scale
thickness diaphragm that allows for lightning fast response that not only
produces stunning levels of detail but ultra-low distortion too. Making
use of technologies originally developed for such revered models as the
HIFIMAN Susvara, and borrowing the same driver shape, the DEVA Pro
offers performance levels and musical purity that exceed expectations,
especially for such an affordable headphone.
The DEVA Pro includes a user-replaceable 3.5mm cable designed for
DEVA Pro only, guarantee the maximum extraction of audio quality. It's
high sensitivity means it will bring out the best from almost any source,
including laptops, digital audio player and mobile phones.
With optional part - Bluemini R2R*, it can even paired with Bluetooth and
USB devices (left side only).
Bluemini R2R should be provided with DEVA Pro wireless version or
need to purchase separately. Bluemini R2R is not the default part of
DEVA Pro.

use two fingers to bend them in and slip them out gently. To install new
pads, align the ear pad with the mounting ring and gently bend the
clips to slot in their appropriate locations.

Please listen to the DEVA Pro at moderate listening levels so that you
can continue to enjoy their audio quality for years to come. You only
have one pair of eardrums, so please look after them.
Do not use any headphone while driving or operating machinery.
For a long product life, the DEVA Pro should be kept away from pets
and small children.
Wipe the surfaces (ear pads, cups, etc.) with a microfiber cloth and
store the headphone in a dry, cool and safe place that is away from
dust, heat, humidity, sunlight, young children and pets. Periodically
wipe the headband to remove any dust.
Planar headphones benefit from break-in to achieve optimum perfor-
mance. This can take up to 150 hours. However, the sound is great out
of the box, so continue to enjoy your headphones throughout the
break-in period.
Modification without authorization, such as changing the transmission
frequency, increasing the transmission power, or other alterations will
invalidate the warranty.
Use only accessories that are officially provided or recommended by
HIFIMAN.
