Artisan Crafted Open-Back Sound

The Fostex TH616 Limited Edition open-back headphone commemorates the 50th anniversary of the birth of Fostex. Carved from high-quality solid black walnut wood in a design reminiscent of traditional Japanese woodwork, the headphone has been crafted into an open housing while achieving reliable acoustic performance. Enjoy a new premium-feeling headphone that combines "Japanese" taste with an excellent acoustic structure, carefully assembled one by one.

Detailed Features

Open housing carved from solid black walnut. The housing is carved from solid black walnut, a high-quality wood, and has an opening with a design inspired by the fantastic natural phenomenon of sunlight shining through gaps in the trees. This machined design not only reduces weight and maintains rigidity, but also avoids uniformity on the housing surface, suppressing the generation of mode vibrations and reducing unnecessary resonance. In addition, in order to eliminate the effect on the sound caused by the resonance of the openings, all the openings vary in layout to suppress the occurrence of resonance at specific frequencies.

Biodyna diaphragm uses ultra-fine bio-cellulose fiber material. Utilizing know-how accumulated over many years, Fostex blended bio-cellulose and other fibers under optimal conditions. Achieves low specific gravity, high Young's modulus, and high internal loss. In addition to delicate, high-resolution, beautiful mid- and high-frequency reproduction, the adoption of free edges with good linearity faithfully reproduces large-amplitude low-mid frequencies.

Super strong magnetic circuit. The magnetic circuit is equipped with a 50mm driver unit with a magnetic flux density of 1 Tesla. The ultra-strong magnetic circuit provides a wide dynamic range with low distortion.

High quality and lightweight mechanical parts. Aluminum is used extensively for mechanical parts, achieving a high quality feel and light weight. By using high-density resin for the baffle plate, a reduction in the generation of resonance sound has been achieved for high resolution, rich midrange, and high-quality bass reproduction.

Detachable connector port. The cable side terminals and the detachable contact terminals on the headphone body side are rhodium plated for high hardness, wear resistance, and corrosion resistance, improving reliability. In addition, it is also possible to support balanced connections with the optional replacement balanced cable ET-H3.0N7BL.

High-performance pure copper headphone cable. A high-performance pure copper HiFC high-grade cable that exhibits excellent conductivity through special processing is used to clearly express all bands.

Soft leather-like high-grade artificial leather pad with low-repulsion cushioning. Provides a comfortable fit and high sound insulation.
