1. Providing atmospheric musical nuances
Large-aperture 70 mm HD (High Definition) driver unit
1 - 1 Magnesium dome diaphragm
Thin film magnesium is used for the dome part that needs lightness and high
rigidity.
The magnesium dome diaphragm propagates vibrations generated from the voice
coil to the dome part, and achieves the reproduction of sound in the super-high
frequency range, 120 kHz. For the edge part where adequate flexibility is required,
the aluminium-coated LCP is adapted. The combination of multiple high internal
loss materials leads to less sound coloration and clear sound.
1 - 2 Large-aperture diaphragm
The 70 mm large aperture diaphragm which exceeds the size of a typical human ear
capsule makes sound waves almost flat. You can experience natural sound, such as
listening to live music, by making sound waves wide and flat.
1 - 3 High magnetic neodymium magnet
The highest grade neodymium magnet with a maximum energy product of
400 kJ/m
is used at the maximum size (*) as the headphones, and the total
3
magnetic flux is increased to the utmost limit. Moreover, we developed the high
efficient magnetic circuit, which minimizes the magnetic flux loss. The high
magnetic neodymium magnet responds the input signal of High-Resolution Audio
with high sensitivity, and provides a precise reproduction of High-Resolution Audio.

1 - 4 Fibonacci pattern grill
The grill of the driver unit applies the pattern of the curve referred to in the
Fibonacci sequence that makes its opening equalize. Also, using the high rigidity
material to thin the crosspiece as much as possible, the propagation of air is not
inhibited and smooth ultra-high-frequency characteristics are made. These lead to
less sound coloration and faithful reproduction of High-Resolution Audio.
