{"product_id":"fostex-th810","title":"Fostex TH810","description":"\u003cdiv lang=\"en\"\u003e\n  \u003cp\u003e\u003cstrong\u003eFostex TH810\u003c\/strong\u003e is a closed-back over-ear headphone with a solid acacia wood housing — the closed counterpart to the TH818 and the direct position below the TH910 flagship in Fostex's premium lineup. The component set is identical to the TH818: the 50mm BioDyna driver with an updated voice coil and reinforced diaphragm surround, a magnesium alloy chassis, dual-density urethane foam earpads covered in silk protein synthetic leather, and a natural sheepskin headband. The closed-back architecture differentiates the TH810 from the TH818 acoustically: stronger, more immediate bass response and passive environmental isolation — at the cost of the wider soundstage characteristic of open-back designs. TH810 is the choice for environments where external noise attenuation matters, or where listening cannot take place in complete silence.\u003c\/p\u003e\n\n  \u003ch3\u003eClosed architecture and BioDyna driver: controlled bass without box resonance\u003c\/h3\u003e\n  \u003cp\u003eThe 50mm BioDyna transducer in the TH810 is the same updated unit as in the TH818 and TH910 — a bio-cellulose and composite fiber diaphragm at 1.5 T magnetic flux density, with a new voice coil and reinforced surround engineered to reduce distortion and artifacts in the bass range. The closed acoustic chamber builds pressure in a way that typically favors the characteristic resonance issues of closed headphones; Fostex minimizes this deliberately through housing material selection and geometry. Acacia wood replaces the Japanese-lacquered maple of the flagship models — acacia is used in stringed instruments including guitars and ukuleles for its resonant properties, which carry over into the acoustic character of the housing. Every TH810 unit shows individual variation in wood grain, texture, and color, with no effect on acoustic performance. Electrical parameters are identical to the TH818: 25 Ω impedance, 100 dB\/mW sensitivity, 1,800 mW maximum input, 12.5 Hz to 40,000 Hz frequency response. Weight is 385 g — approximately 20% lighter than the previous generation due to magnesium alloy use in the headband and yoke assembly.\u003c\/p\u003e\n\n  \u003ch3\u003eComfort materials and cabling: sheepskin, silk protein leather and 7N OFC\u003c\/h3\u003e\n  \u003cp\u003eThe headband pad is covered in natural sheepskin leather. Earpads are built from dual-density urethane foam covered in silk protein synthetic leather — softer and more peel-resistant than standard PU, with a more natural feel against skin during extended sessions. The included cable is 3.5mm with 7N oxygen-free copper conductors and a 6.3mm adapter in the box. The detachable cable connector uses rhodium-plated contacts. Balanced connection is supported via the separately purchased XLR cable (ET-H3.0N7BL).
