Sony PFR-V1 headset [speaker] system atlas

SONY PFR-V1 is a very interesting product. PFR is the abbreviation of Personal Field Speaker. Sony named it as a personal sound field speaker system. This product was released in January 2008 at CES, but it has been discontinued for sale. The price is 53,000 yen. As shown in the figure, it is a device that puts two spherical speakers at a certain distance from the human ear, and uses two brackets to extend the outer ear and strengthen the low frequency with a certain bone conduction. Wearing speakers and headphones actually have a distinctly different experience. AKG K1000[KK], SONY SRS-AX10 speakers have similar positions when worn. Thank you very much for sending this precious product. Soomal is also the first to experience this. The product, although the product has been discontinued, and separated from the release year, we are still very interested in this product.
