The HFI-15G headphones provide the user with a natural surround sound listening experience without the use of additional equipment and offer one of the industry's largest frequency ranges at 20Hz to 20kHz. The HFI-15G's also are 40% safer for your ears, allowing for safer listening at higher levels.
These lightweight headphones can follow you easily. You
barely feel it when you wear them. The open-back design of the Ultrasone
HFI-15G is highly appreciated for mobile applications or as hearing aid
for watching TV. This is the smallest headphone of the Ultrasone HFI
line, convincing with its pure and spacious sound.
Through the
S-Logic Natural Surround Sound the usual headphone sound will be moved
out of the head in the room around you. The sound is no longer locked
in, but appears broad and detached. Directions and distances can be
heard and perceived - it?s just like being in a live concert. For this
new technology additional equipment is not required. Take a pair of
Ultrasone headphones plus your sound device and you will be ready for
the 3-dimensional sound enjoyment!
S-Logic does not only create a Natural Surround Sound. S-Logic allows
at the same time a reduction of sound pressure levels by up to 40% (3-4
dB) for the same loudness sensation. This may reduce the risk of
hearing damage while ensuring hours of fatigue-free listening. However,
Ultrasone generally advises not to listen to music at high volumes to
prevent hearing damage.

10
Reasons
to
use
Ultrasone
1. S-‐LogicTM
Natural
Surround
Sound:
The
sound
is
moved
out
of
the
head
in
the
room
around
you.
The
sound
appears
broad
and
detached.
Directions
and
distances
can
be
heard
and
perceived
–
as
if
you’re
in
a
live
concert
or
in
the
sweet
spot
of
fine
monitor
speakers.
2. Less
hearing
fatigue:
Listening
(or
working)
with
headphones
causes
hearing
fatigue
rather
quickly
(ouch
my
ears
hurt).
With
S-‐Logic
the
sound
into
your
individual
ear
reduces
hearing
fatigue
close
to
zero.
3. Hear
more
details:
One
of
the
most
important
facts
for
the
working
musician,
engineer,
or
producer!
You
are
able
to
hear
more
detail
and
nuances.
For
a
consumer,
you’ll
discover
hidden
gems
you
never
heard
before.
4.
Safer
hearing:
S-‐LogicTM
reduces
sound
pressure
levels
(3-‐4
dB)
up
to
40%
for
the
same
perceived
loudness.
This
may
significantly
reduce
the
risk
of
hearing
damage
-‐
a
must
if
you
spend
a
lot
of
time
in
headphones.
5.
Patented
ULE
Technology:
Ultra
Low
Emission:
Unlike
other
headphones,
with
ULE
you
have
*radiation
protection.
Electro-‐magnetic
emissions
are
cut
to
approximately
98%.
Without
ULE
it’s
as
if
you
put
5
computer
CRT
monitors
directly
on
your
head.
ULE
is
very
important.
6. Design:
Reviewers
have
spoken
glowingly
and

words
like
“upscale
and
elegant”
and
have
written,
“...the
combination

high
style
and
stellar

and
cutting
edge
look.
