Fostex TH616 Limited Edition Premium Open-Back Audiophile Headphones – Solid Black Walnut Housing, 50 mm Bio-Dyna Drivers

Unlock the ultimate listening experience with the Fostex TH616 Limited Edition—a premium open-back headphone crafted for discerning audiophiles and wood-cup aficionados. Celebrating the 50th anniversary of Fostex, this model features hand-assembled construction in Japan, and a striking aesthetic carved from solid black walnut that not only impresses visually, but also contributes to acoustic integrity.

Designed with a philosophical nod to natural light filtering through trees, the open-housing architecture is intentionally machined to reduce resonances and deliver a refined, spacious soundstage. Under the hood, the TH616 harnesses Fostex’s advanced Bio-Dyna diaphragm (ultra-fine biocellulose fiber) and a robust 50 mm driver with a 1 Tesla magnetic circuit, achieving a remarkably wide 5 Hz–45 kHz frequency response and ultra-low distortion performance.

Complementing the high-end acoustics, you’ll find a premium cable with rhodium-plated detachable connectors, a soft low-resilience artificial leather ear pad for extended comfort, and a luxurious leather pouch for safe transport. Whether you’re mixing in the studio, immersing in high-res audio, or simply indulging in top-tier sound at home, the TH616 stands out for its combination of build quality, sonic purity and discriminating design ethos.
