Features

Sony redefines the world of sound with its new 2007 PFR-V1 Personal Field Speaker that mimics audiophile grade front-facing speakers. First in the industry (and the world) to separate bass from mid and treble frequencies so that users can hear even better sound. Bass sounds are reproduced through a new "extended bass reflex duct" which extends directly into the ear canals. Mid and treble frequencies are projected through the two unique looking spheres towards the ears just like a pair of two perfectly positioned speakers. Result? An extended frequency playback of 35Hz to 25KHz, with better frequency separation. The new, and one-of-a-kind "Personal Field Speaker" PFR-V1 comes with ultra large drivers of 21mm (newly developed by Sony) for superb sound reproduction. A new flagship headphone, or should we say, speaker-on-your-head on the market.
