Designed
to be the Very Best In the World
The
Housing
After
extensive testing of materials from all over the world, the
heart-wood of mature Zelkova trees was selected as most suitable
for the housing of the MDR-R1O. Evaluation was made in terms of
hardness, timbre, weight, and overall sound-transferability
characteristics. In order to overcome the problem of designing
housing that could produce a natural, distortion-free sound,
engineers used the FRESDAM (Freeform Shape Design and
Manufacture) computer-aided design system. A delicate waveform
was carved out of the interior wall, achieving sound expansion
and acoustics equivalent to that of a concert hall.
The
Headband
The
housing position is set automatically when placed on the head,
due to a shape-memory alloy employed in the self-adjusting
head-band. Regardless of head size, the super-elasticity of the
headband applies just enough inward pressure to create the proper
acoustic space between the ear and the housing.
The
Diaphragm
Using
leading-edge biotechnology techniques, a natural fiber
(bio-cellulose) produced by a bacteria called Acetobacter acti
is dehydrated, then compressed to a thickness of 20 microns in a
diaphragm die. The advantage of the ultra-thin bio-cellulose
diaphragm is that it can produce the same sound velocity as an
aluminum or titanium diaphragm, along with the warm, delicate
sound that a paper diaphragm provides. Trebles are sparkling
clear, and bass notes are remarkably deep and rich.
The
Holder
Hangers
made of magnesium that attach the housings to the head-band
reduce resonance. Magnesium was chosen because of its excellent
vibration attenuation and absorption qualities. To prevent
mechanical vibration, such as those of the cord or headband, a
housing insulator was placed between the ear pad and the baffle
plate.
The
Earpads
To
provide the ultimate in comfort, Greek lambskin covers the
entire earpads, along with the headband and suspender Renowned
world-wide for its velvety softness and smoothness, the lambskin
affords a luxurious feel that allows even the wearer with the
most sensitive skin extended listening comfort.
The Cord
and Plug
The cord
wires are made of 99.9999% pure, linear-crystal oxygen-free
copper to prevent signal loss during transference. A durable,
soft silicon insulates the wires, and the insulation is coated
in 100 % pure double-woven silk. The OFC plug is double-plated;
once with rhodium to prevent signal loss, and the second time
with gold to prevent sound quality deterioration from imperfect
contact. |
