Built with 60mm nanowood fiber composite drivers and a closed-back design, it provides clarity and depth while controlling resonance. The use of North American walnut or beech wood gives each pair a unique look with distinct grain patterns.\nNatural Wood Shells for Authentic Sound\nEach FT1 ear cup is made from solid walnut or beech wood. The natural density of wood helps reduce resonance and standing waves, while adding a warm, organic character to the sound.\n60mm Nanowood Fiber Composite Driver\nA large 60mm driver with a nanowood fiber composite diaphragm ensures wide frequency response, with both impactful low-end and refined treble reproduction.\nAcoustic Tuning with Precision Design\nThe FT1 features a conical baffle plate,
