Personal Field Speaker (2007)
The PFR-V1 was a revolutionary new headwear, a "Personal Field Speaker" that allowed users to enjoy a highly realistic sound experience. It proposed a new style that differed completely from conventional headphones, eliminating any departure from natural, open field sound. The shape relates to the function— the speakers are lifted away from the face to reduce echo waves. Special effort was put into the frame design to represent lightness in look and feel, as well as in actual weight.
