FiiO x Jade Audio JT7 - Planar open headphones

Flagship Planar Technology at Hand

Planar open headphones with an ultra-light, foldable design with a proprietary 95 × 86 mm transducer

Next Generation Open Planar Headphones

The FiiO x Jade Audio JT7 is a wired open planar headphone that redefines the relationship between audiophile orthodynamic technology and everyday convenience. Traditional planar headphones have been associated for years with considerable weight, rigid headbands and current requirements forcing the use of powerful stationary amplifiers. Designers of the FiiO and Jade Audio brands broke this pattern by creating a structure weighing only 318 grams, equipped with a full folding mechanism and a high-sensitivity transducer, capable of working with both mobile devices and advanced desk equipment.

The open design of the JT7 guarantees free air flow and no sound wave compression, which directly translates into a natural holographic music scene. Unlike dynamic transducers, the electromagnetic force in this model works evenly over the entire surface of the membrane, eliminating division distortion. The whole has been verified with a rigorous Hi-Res Audio certificate, certifying precise and faithful reproduction of the full acoustic band.

Original planar transducer 95 × 86 mm and ultra-thin membrane 3 m

The heart of the headphones is a large-format, proprietary planar transducer with dimensions 95 × 86 mm, designed and made entirely internally by FiiO engineers. Full control over the research and development process – from the chemical properties of the membrane, through the paths of the vibrating coil, to the magnetic circuit – allowed to achieve unprecedented repeatability and phonic consistency of the transducers. The large active surface of the diaphragm allows you to freely generate deep, resilient bass without the need for artificial boosts with an equalizer.

The key element responsible for the phenomenal speed of transients is the ultra-thin membrane with a thickness of only 3 micrometers (3 m). The reduced moving mass reacts immediately to the smallest electrical impulses transmitted from the amplifier. In practice, this means crystal clear treble, no microdetail masking phenomenon and the ability to accurately render the attack of percussion instruments or of acoustic guitar strings.

Innovative F.E.S. system and 28nm semiconductor coil integration

In conventional planar constructions, flat film faces harmful internal stresses that limit its tilt in the lowest registers. To solve this problem, FiiO developed the patented F.E.S. (FIIO Elastic System) spring system. Multidimensional textures were embossed on the surface of the membrane, which play a role similar to suspension in dynamic transducers. This solution introduces an additional dimension of film flexibility, allowing for free, non-linear counteraction of material stresses. The result is a higher tilt amplitude and a generous, perfectly controlled bass with a perceptible texture.

An advanced electroplating process taken from the semiconductor industry with a precision of 28 nm was used to apply conductive paths to the membrane – identical to the technology used in the flagship models FiiO FP3, FT1 Pro and FT7. In this way, the coil and substrate form a uniform, seamless molecular structure without the use of thick adhesive layers. This guarantees exceptional mechanical integrity, long-term durability and elimination of the risk of path delamination under the influence of continuous operation.

Lightweight, foldable design and glass fiber composite hinges

With a weight of just 318 grams, the FiiO JT7 ranks among the lightest full-size planar headphones on the market. Low weight significantly reduces pressure on the top of the head and eliminates neck fatigue during long hours of listening. The designers have integrated a fully folding headband, which allows you to fold the shells inwards and turn them flat. This makes it easy to easily stow your headphones into the included travel case and take them on any route.

Hinged elements made of high-strength glass fiber composite are responsible for the reliability of the folding mechanism, which offers stiffness and crack resistance parameters far superior to traditional plastic. In the course of research and development, the hinges were subjected to rigorous laboratory tests: more than 10 000 sliding cycles, more than 10 000 twisting tests and tensile loads exceeding 5 kg. This guarantees loose, smooth operation of the structure for years of intensive use.

Ergonomics, breathable ear cups and full modularity

The ergonomic headband of the JT7 headphones is equipped with a adjustment system in four axes, which allows precise adjustment of the angle of the shell to the anatomical shape of each user's head. Proper adhesion of the ear cups guarantees optimal acoustic sealing, which in open structures is necessary to maintain the full woofer band and the correct distribution of the sound stage.

The ear cushions in the zone of direct contact with the skin are finished with highly breathable textile mesh (mesh), which dissipates excess heat and reduces sweating of the ears on warm days. Both the ear cups and headband cushion are fully removable. The modular design allows for instant cleaning of upholstery elements or their replacement with new ones after years of use, which prolongs the life of the equipment and protects the user's investment.

Double-sided NdFeB magnets, wiring and source selection recommendation

The performance of the headphone drive was based on two-sided, heterogeneous neodymium-iron-boron magnets (NdFeB) with high flux density. The strong magnetic field provides a sensitivity of 92 dB/mW with an extremely low impedance of 18 Ω. Thanks to this, the JT7 does not require a stationary power plant to sound loud and clear – they can be powered by high-end portable DACs/Amp converters.

The manufacturer equipped the headphones with 3.5 mm jack sockets in each shell and a rich package of wires. The package includes a single-ended 3.5 mm cable, a balanced 4.4 mm Pentaconn cable and a screw-in 6.35 mm to 3.5 mm adapter, which gives immediate compatibility with all audiophile connector standards without the need to buy accessories.

In terms of the selection of the listening track, FiiO recommends the use of balanced outputs of portable devices with an output power exceeding 500 mW – such as dongles and players FiiO KA15, KA17, QX13, BTR17, M21, DM13 or DM15 R2R, which easily ensure full control and proper sound pressure. For enthusiasts looking for maximum dynamics, authoritative bass and full stage momentum, stationary drivers with an amplifier will be the ideal partner, e.g. FiiO K11, K11 R2R, K7 or higher class constructions.
