Fiio JT7 Open Back Planer Wired Over Ear Headphones Black

FiiO, in collaboration with Jade Audio, presents the JT7, a fully in-house–developed planar-magnetic headphone designed for pure, lifelike sound. From diaphragm research and magnetic circuitry to voice-coil architecture, every element is meticulously crafted under FiiO’s control for consistent acoustic excellence. Its 95 x 86 mm proprietary planar driver delivers an expansive soundstage, quick transient response, and powerful, controlled bass. Certified for Hi-Res Audio, the JT7 stands as a professional recognition of FiiO’s commitment to precise, high-fidelity reproduction. The result is a headphone that marries advanced semiconductor-grade engineering with a comfortable, portable design built to reveal every musical detail with accuracy and energy.

Fused With 95 × 86 mm Planar-Magnetic Driver For High-Fidelity Audio

FiiO JT7 features a 95 × 86 mm planar-magnetic driver developed entirely in-house. Unlike traditional dynamic or balanced-armature designs, its diaphragm is driven evenly by electromagnetic force across the entire surface. This uniform motion eliminates sectional distortion, resulting in ultra-low distortion levels, superior transient response, and a vast, holographic soundstage. Though complex to manufacture, the planar architecture delivers detail, speed and power in perfect harmony.

Features Ultra-Thin 3 µm Composite Diaphragm For Speed And Accuracy

FiiO JT7 features a 3 µm ultra-thin composite diaphragm engineered for effortless movement and exceptional agility. Its feather-light structure captures minute electrical signal changes with precision, allowing micro-details and transient nuances to shine. The result is treble that sparkles with clarity, midrange that breathes naturally, and bass that remains tight and articulate for a clean and transparent tonal balance.

Embeds FIIO Elastic Suspension F.E.S. System For Enhanced Driver Control

FiiO JT7 incorporates FiiO’s proprietary Elastic System F.E.S., a multidimensional texture applied to the diaphragm surface that increases elasticity. Similar to the surround ring of a dynamic driver, this structure distributes internal stress more evenly, enabling smoother diaphragm motion with minimal distortion. The added elasticity allows richer, fuller bass reproduction while maintaining precision and control, giving the JT7 a powerful yet effortless low-end output.

28nm Precision Magnetic Chip & Dual N52 Magnets For Superior Efficiency

FiiO JT7 is built using a 28 nm semiconductor-grade plating process derived from FiiO’s flagship models, seamlessly integrating the voice coil, diaphragm, and magnetic circuit for superior stability and efficiency. Its two-way neodymium-iron-boron magnets generate a strong, uniform magnetic field, achieving 92 dB/mW sensitivity and effortless driveability. This precision engineering ensures exceptional transient response, dynamic impact, and clean, distortion-free sound that remains consistent over time.

Lightweight Built Design With Breathable Cushions For Seamless Experience

FiiO JT7 weighs only 318 g, making long listening sessions effortless and comfortable. Its foldable frame and multi-axis ergonomic headband 90° fold, 35° horizontal, 45° pitch, 38 mm slide ensure a precise, adaptive fit while allowing compact storage for easy portability. The soft, breathable mesh earpads minimise heat build-up, and both the earpads and headband cushion are detachable for convenient cleaning or replacement. Thoughtfully engineered for durability, flexibility, and all-day comfort, the JT7 is built to move with you at home, in the studio, or on the go.

Comes Bundled With Multiple Detachable Cables For Versatile Connectivity

FiiO JT7 comes bundled with multiple detachable cables to accommodate diverse setups – a 3.5 mm single-ended, a 4.4 mm balanced, and a 6.35 mm adapter. Each cable uses dual 3.5 mm connectors for secure, reliable signal transmission. This versatility lets listeners easily match the JT7 with portable DACs, desktop amplifiers, or professional interfaces, ensuring the ideal balance of convenience and audio performance.
