Fostex TH616 Limited-Edition Open-Back Headphones

TH616 Limited-Edition Open-Back Headphones — Limited-Edition Walnut, Machined for Openness

The TH616 is a limited-edition open-back headphone assembled in Japan around Fostex’s 50 mm BioDyna driver. Its solid black-walnut housings are intricately machined into an acoustic opening that is both structural grille and visual signature.

The BioDyna diaphragm is designed for low mass, high rigidity and controlled internal loss, helping the TH616 move cleanly from extended bass through a detailed, naturally projected midrange. A detachable HiFC pure-copper cable and replaceable pads support long-term ownership.
