Congratulations!
You
are
now
the
proud
owner
of
a
pair
of
headphones
resulting
from
many
years
of
R&D
led
by
a
team
of
passionate
audio
and
acoustics
engineers,
material
scientists,
chemical
technologists
and
audiophiles.
The
OPPO
PM
‐
1
utilizes
a
planar
magnetic
driver
that
sets
it
apart
from
the
majority
of
headphones
on
the
market.
In
our
planar
magnetic
headphone,
sound
is
generated
by
a
very
thin
and
light
diaphragm
whose
entire
surface
area
is
evenly
driven.
The
diaphragm
is
driven
in
a
symmetric
pull
‐
push
manner,
and
the
magnetic
system
and
conductor
patterns
have
been
optimized
for
maximum
sensitivity
and
consistency.
This
allows
the
diaphragm
to
generate
very
stable
and
linear
piston
‐
like
vibrations,
ensuring
phase
coherence
and
high
resolution
performance
with
minimal
distortion.
