Fostex’s model TH900mk2 is the second generation of the TH900, one of the most renowned premium dynamic headphones in the market. This special edition model features ‘Pearl White’ cups and the same anniversary tuning found in the SB model, with more relaxed highs and neutral low end. The TH900mk2 adds detachable connectors for easy replacement of the standard unbalanced cable, switching to the optional balanced 4-pin XLR cable (ET-H3.0N7BL), or for using third party cables. The TH900mk2 features a unique Japanese traditional Urushi lacquer, applied to Japanese cherry birch (Betula Grossa) cup housings. Betula grossa the wood from this tree is rigid and dense. It is prized as a fine wood for furniture production. The Pearl White “Urushi” finish is a traditional lacquering technique developed by a group of Japanese artisans founded in 1900. This exclusive lacquer finish not only gives the headphone housings an elegant and sophisticated visual appeal, but also it improves the housings’ durability. The process requires various meticulous steps. Numerous sulphur smoked silver foils are adhered on a black-lacquered base, creating a torn paper type collage. This is then finished with a rich Bordeaux-wine translucent paint. As a finishing touch and for an added sense of luxury, platinum leaves are used to detail the Fostex brand logo on each cup. Each cup holds the reputed proprietary Fostex ‘bio-dyna’ free edge 50mm diaphragm, driven by a very powerful 1 tesla (1,000 gauss) magnetic circuit. The Biodyna diaphragm is made of a bio-cellulose fibre featuring low specific gravity, high Yang’s modulus and high internal loss, to achieve double propagation velocity and five times the rigidity compared to a conventional plastic film diaphragm. In real times this offers an extremely wide dynamic range with low distortion and a very balance presentation across a wide frequency range. Each cup uses a low repulsion cushion earpad covered with protein leather made from eggshell membrane, this is 60% lighter than genuine leather so offers very high levels of comfort. The thick 7N grade (99.99999%) OFC cables, with soft fabric weave sheaths, are exclusively manufactured for the TH900mk2 to transmit a very low distortion signal and to specifically enhance low frequency reproduction. A hard, wear and corrosion resistant, rhodium plating is applied to the 2-pin headphone connector as well as in the cup terminal, with a duralumin coating applied to the plug housing, to ensure reliability and long-life. Enclosure type: Closed Drivers: Neodymium magnet / 50mm Bio-dyna diaphragm Impedance: 25 ohm Sensitivity: 100dB (at 1kHz, 1mW) Max Input: 1800mW Freq. response: 5Hz – 45KHz Weight: Approx. 390g (excluding cable) Package content: 3m, 6.35mm / ¼” 7N grade OFC detachable 2-pin rhodium coated, fabric weave cable, leatherette carry bag, wooden headphone stand, colour brochure, manual.
