Fostex unveils TH810 and TH818 premium over-ear headphones

Fostex has announced the upcoming TH810 closed-back and TH818 open-back premium over-ear headphones. Both utilize the same components as the previously announced flagship TH910 and TH919 headphones, but use more affordable acacia wood housings rather than Japanese-lacquered maple housings decorated with sulfur-smoked silver foil patterning.

Both over-ear headphones leverage the company’s 50mm BioDyna driver, with an updated design that uses a new voice coil and driver surround to help deliver bass with low artifacts and reduced muddiness, according to Fostex. The drivers have a frequency response of 12.5 to 40,000 Hz, with an impedance of 25 ohms and a sensitivity of 100 dB/mW. These premium headphones are designed for high-power amps and can handle inputs up to 1,800 mW over the included 3.5 mm oxygen-free copper cable (7N).

Lightweight magnesium alloy is used to drop the weight of the headphones by approximately 20% over the prior models, and both headphones now weigh 13.6 oz. (385 g). The headband uses natural sheepskin padding while the ear cups use silk protein synthetic leather over contoured, dual-density urethane foam.

Readers can look for the TH810 and TH818 at authorized distributors worldwide and in the Fostex store on Amazon when they begin shipping in late April 2026. Pricing has not been announced, but they will likely start around $1,000.
