multi-layer diaphragm (comprised of hundreds of layers of

material, which easily folds and

3,000 mW power handling capacity and 80 
kHz ultra high frequency reproduction, these

the driver units have been designed in accordance with the 
angle of the ear, which helps to eliminate pressure on the ear and 
to reproduce a natural, wide soundscape.
