FOSTEX Open Dynamic Premium Headphones TH616 Black Walnut Solid Wood Specifications [Model] TH616(AZ)

Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. This product is a [package model] of FOSTEX's popular open dynamic premium headphones TH616 made of solid black walnut. [Open-type housing carved from solid black walnut wood into a shape that resembles a beam of light] The housing is carved from high-quality solid black walnut wood, creating an illusion created by the sunlight shining through the gaps in the trees through the open-type opening. We adopted a design inspired by the rays of light, which is a natural phenomenon. This machined design not only reduces weight and maintains rigidity, but also avoids uniformity of the housing surface, suppressing the generation of mode vibrations and reducing unnecessary resonance. In addition, in order to eliminate the impact on sound caused by resonance of the open openings, all openings have different areas to prevent resonance at specific frequencies. [Uses a Biodyna diaphragm using ultra-fine biocellulose fiber material] Utilizing the know-how accumulated over many years, biocellulose fiber and other fibers are blended 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 a free edge with good linearity faithfully reproduces large-amplitude low-mid frequencies. *“Biodyna” and “BIODYNA” are registered trademarks of Foster Electric Co., Ltd. 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. In addition, aluminum is used extensively for mechanical parts, achieving a high quality feel and light weight. By using high-density resin for the baffle plate, we have reduced the generation of resonance sound, achieving high resolution, rich midrange, and high-quality bass reproduction. 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". Adopts a pure copper Hi-FC high-grade cable that exhibits excellent conductivity through special processing, and clearly expresses all bands. *“Hi-FC” is a registered trademark of Hitachi Metals, Ltd. In addition, the soft leather-like high-quality artificial leather pad uses low-repulsion cushioning to provide a comfortable fit and high sound insulation.
