In case anyone at all's interested in the quick (I know, it's not very good

) translation:
The PFR-V1 brings a new style that puts the speaker directly on your head.
Enjoy big sound without the sense of pressure using small speakers.
Using the reflective properties of the ear concha(I think that's the word), the speakers faced diagonally toward your ears
will sound like a live performance. Mid-high's are sounded directed in such a way that gives the illusion of sound coming
from the front. The bass uses newly developed "extended bass lef duct"(? translated as pronounced) that direcly pumps the bass into your outer canals, which
gives a high quality and spatial bass. This method delivers a life-like soundstage
Personal field speaker system:

Extended Bass Lef Duct effects:

(comparison between previous "bass lef duct" to the new "bass lef duct)
Eliminating unwanted sounds, reproducing clear audio
Small speaker cabinet
By minimizing the speaker size, unwanted frequencies produced with traditional speaker units are eliminated, allowing for a clearer sound.

Blow up of the speaker unit:

<a> center cap (mainly reproduces mid-high frequencies): using silken material, precise and beautiful highs are reproduced
<b> voice coil (transforms analogue signal into vibration): using CCAW, it's light properties is designed for high quality high frequencies
<c> magnet (operates magnet): using 440 kJ/m^3 neodynium magnet
<d> frame (holds speaker unit parts in place): liquid polymer is used
<e> plate, york(?) (signal path for magnets): (sorry I can't translate this...)
