To celebrate Audio-Technica's 50th Anniversary, A-T has introduced special limited edition ATH-W3000ANV headphones. The ATH-W3000ANV is the embodiment of 50 years of Audio-Technica headphones expertise. The ear pieces are made from strikingly beautiful traditional Japanese Echizen lacquer-finshed Hokkaido Asada cherry heartwood. The ATH-W3000ANV is engineered for superlative sound quality, with special high-power driver magnets, OFC 7N ultra-high-purity oxygen-free-copper voice coils and isolated left/right internal wiring, and a newly-designed 53 mm wide-range driver element. The frame is constructed from magnesium for exceptionally light weight and high rigidity, and the ear cushions are fabricated from luxurious Spanish lambskin. Like all 2012 Limited Edition products, the ATH-W3000ANV features a 50th Anniversary logo and commemorative certificate signed by our president, Kazuo Matsushita.<br/><a href="http://www.audio-technica.com/cms/50th_anniversary/index.html/" target="_blank">To read about A-T's history & see more 50th Anniversary Limited Edition products, click here.</b></a>
