Based on a new 50 mm diameter BioDyna diaphragm, powered by a neodymium magnet, the new Fostex closed-back TH910 and open-back TH919 models improve sound amplitude and reduce feedback. The frequency response is advertised as covering a wide range from 12.5 Hz to 40 000 Hz.
Thanks to their new structures, these new flagship models are also 20% lighter, with some aluminium parts replaced by magnesium. Carefully painted with traditional Japanese Urushi lacquer by Sa-kamoto Otozo Shoten Co., Ltd, these headphones set new standards in terms of components (7N OFC copper internal cables) and comfort (new high-resilience urethane foam to adapt to the shape of the head, new synthetic leather made from silk protein).
Weighing approximately 385 g (excluding cable) and with an impedance of 25 ohms and a sensitivity of 100 dB/mW, these new headphones come with a leather pouch and a detachable 2 m asymmetrical cable, with two 3.5 mm jacks to connect to the headphones on one side, and a gold-plated 6.35 mm plug to connect to the amplifier on the other. A 4.4 mm symmetrical cable is currently in development.
The TH910 and TH919 are the brand’s new flagship headphones and are priced at 3 290 € and 3 490 € including VAT in Europe.
