Product Overview
The HIFIMAN HE-400i
is
an
open-backed headphone
with
specially
designed planar magnetic drivers. Connection
is
made
via
the supplied
cable with screw-on connectors using separate ground leads
for
each
channel to minimize crosstalk between the channels.
Using single-ended drivers, HE-400i delivers a lifelike soundstage and
spatial imaging. Its increased efficiency
of
93dB allows
it
to
be
driven
with
a modest size
amplifier
or
even be used
with
a portable audio
player
or
smart phone.
HE-400i
is
30%
lighter than comparable planar magnetic headphones
allowing the listeners
to
comfortably enjoy music
for
hours on end. In
addition, a newly-designed headband and beveled hybrid earpads
provide added comfort
as
well
as
improved sound quality.

Headband Adjustment
If
the
top
of
the headband does
not
touch your head, move the sliding
black block on each side
of
the headband
so
that
the headband rests on
top
of
your head.
Earpads replacement
To
replace the earpads, you must first remove them. Then you will
see
there
is
gap between
two
screws inside the driver. Insert the
two
adjacent plastic clips inside the earpads into the gap.
Use
your middle
finger
to
hold the earpads inside while your
thumb
holding the outside.
Push
the earpads slightly with your
thumb
until the remaining clips
are
inserted. Revolve the earpad
so
that
it
is
firmly installed.

Set-up and Operation
1.
To
obtain
optimum
performance, please allow at least 150 hours
of
constant
use
for
break-in
of
your
new headphone. This break-in period
does
not
have
to
be at high volume.
2.
To
connect your headphones
to
an
amplifier, please use the supplied
cabling.
The
mini-coax plug with the
red
dot
goes
to
the right side
marked with
R.
(Depending on the cable in
use,
the cable itself
can
also
show Land
Ron
the plugs.)
Push
the connector straight
onto
the socket
and then
use
your fingers
to
tighten the washer. When tightening,
please make sure
to
move
the
washer only and
not
the cable
as
such. A
loose connection
can
lead
to
drop outs and distortion. Repeat the
process with the other mini-coax connector.
3.
The
supplied cable adapter with the large 1
/4"
(6.35mm) jack
is
connected with the typical headphone
output
of
an
amplifier
or
even
better with a headphone amplifier.
Please
be aware
that
many home
amplifiers will switch
off
the loudspeaker
output
when a headphone
is
connected.
4.
To
clean your headphone, please
use
a soft, slightly damp cloth only.
Do
not
use any detergents and make sure
not
to
let any fluid enter the
open sides
of
the headphone. The leather headband
can
be maintained
using standard leather care products. When your earpads become worn
and no longer offer a
good
connection
to
your head, you should
replace them with new ones which
can
be supplied from your dealer,
or
head-direct.com. Note: The internal drivers
do
not
require maintenance.
Any
attempt
to
remove
or
modify
them will void your warranty.
