About This Items

▼ Product overview

This product is a premium headphone developed based on Fostex's top open headphone type TH909. The housing technology is carved from solid black walnut, a high-quality wood, and is equipped with a unique in-house Biodyna diaphragm driver unit. Based on an open design that integrates photo-etched aluminum parts, it has been put together with precise acoustic tuning. We are looking forward to receiving your new premium headphones, each carefully assembled one by one at our domestic factory.

▼ Equipped with an in-house driver unit that boasts a magnetic flux density of 1.5 Tesla from the TH900 series, and has undergone TH808 original acoustic adjustment to achieve delicate, high-resolution sound quality over a wide band.

Our in-house driver unit, developed using proprietary technology accumulated over many years, has a diaphragm blended with biocellulose fibers and other fibers under optimal conditions, achieving low specific gravity, high Young's modulus, and high internal loss. Adopting a neodymium magnet repulsion magnetic circuit, the low distortion and ultra-strong magnetic circuit with a magnetic flux density of 1.5 Tesla and good free edge linearity provide excellent response in all bands and a vast dynamic range. In addition to delicate, high-resolution, beautiful mid- and high-frequency reproduction, it also faithfully reproduces large-amplitude low-mid frequencies.

▼ Original open housing made of solid black walnut and aluminum materials

The housing is carved from solid black walnut, a high-quality wood, and has an original design with two layers of etched aluminum parts that change the impression depending on the light and angle at the open opening. The careful fine-tuning of the aperture ratio and each internal part, coupled with the resonance of solid black walnut, reproduces a natural sound field that is comfortable and less tiring to listen to.

▼ TH808 original high purity OFC unbalanced cable included

Equipped with a detachable connector port and uses 7N grade cable for internal wiring.

▼ Ear pads with low-repulsion cushioning

It fits perfectly behind the ear to reduce sound leakage, and uses low-resilience cushioning and carefully selected high-quality synthetic leather to provide a comfortable fit and feel even when used for long periods of time. It uses the same ear pads as TH909.
