Final D7000

The Final D7000 is part of the Japanese brand’s high-end headphone series. It’s an open-back model equipped with planar magnetic drivers, combining the treble reproduction characteristic of this technology with bass response comparable to that of dynamic drivers. It is 16% lighter than the D8000 models and features the Pinna-Aligned diffuser along with a revamped AFDS system, positioning it between the D8000 and the D8000 Pro Edition.

A sonic balance between two worlds

The D7000 occupies a unique place in the D Series lineup. Where the D8000 excelled with classical music and wide dynamic range recordings, and where the D8000 Pro Edition proved more resolved with rock and pop featuring a narrow dynamic range, the D7000 sits between the two. Final describes this model as the most versatile of its flagship headphones, able to adapt to all music genres without favoring a particular sound aesthetic.

This versatility is based on a meticulously crafted balance. The D7000’s planar magnetic drivers deliver the delicate highs inherent to this technology, while the AFDS system reworked for this model enables bass reproduction as expansive and open as that of a quality dynamic driver. This marriage of characteristics from two different technological worlds is accompanied by high resolution in the vocal and string registers, with a sound signature described as smooth and silky.

The D7000 also distinguishes itself from its predecessors in its amplification approach. With a sensitivity of 89 dB/mW versus 98 dB/mW for the D8000s, this headphone demands more power. This lower sensitivity brings it closer to other demanding planar headphones on the market, requiring an amplifier capable of delivering sufficient current to fully exploit its capabilities. Users with balanced amplification will get the most out of this headphone.

The Pinna-Aligned diffuser: tailoring sound to each ear

The D7000’s major innovation lies in its Pinna-Aligned diffuser, a technology new to Final. The concept draws inspiration from acoustic diffusion principles used in modern recording studios. From the earliest stages of D8000 development, Final considered integrating a diffuser, but developing a system suited to the unique conditions within a headphone enclosure took several years.

The challenge stemmed from the variation in the shape of the ear’s pinna from person to person. Measurements taken with test instruments under ideal conditions yielded good results, but real listening revealed marked differences depending on each individual’s outer ear morphology. To solve this problem, Final conducted numerous simulations based on different pinna shapes, accompanied by listening tests with real listeners. This work led to a diffuser shape that is optimal for all users, regardless of their morphology.

The diffuser is placed in front of the planar magnetic driver and helps even out acoustic distribution. This approach makes it possible to achieve a consistent sound signature from one listener to another, rather than large variations depending on the pinna shape. The D7000 thus becomes Final’s first headphone to benefit from this pinna-aligned diffusion technology.

The reworked AFDS for optimal diaphragm damping

The AFDS (Air Film Damping System), Final’s patented technology, is the other technical pillar of the D7000. Conventional planar magnetic headphones face a physical limit: at high volume, the diaphragm’s excursion when reproducing bass can become so great that it risks contacting the surrounding magnets. To avoid this, manufacturers typically design their drivers with a higher low-frequency cutoff than ideal, then compensate by sealing the ear pads to create a closed space in front of the diaphragm. This solution works, but produces bass in a confined space, similar to in-ear monitors, without the sought-after sense of openness.

Final developed AFDS after performing finite element diaphragm simulations and measurements with laser Doppler devices. The system consists of perforated metal plates suspended on either side of the diaphragm, literally creating an air film between the diaphragm and its magnets. This acoustic resistance damps the diaphragm in a controlled manner, allowing it to extend lower in frequency without the risk of contacting the magnets.

For the D7000, Final revisited the diaphragm coil shape and the perforated metal, enabling more effective damping tailored to the target physical characteristics of this model. Thanks to AFDS, the D7000 can reproduce a sufficient bass range even with breathable pads, without requiring the usual seal. Paired with the new highly breathable washi pads, the system delivers rich bass with a natural sense of openness.

A lighter diaphragm for uncompromised treble

The D7000’s diaphragm illustrates Final’s obsession with lightness in high-frequency reproduction. Compared to a dynamic driver of the same diameter, the D7000’s diaphragm weighs only one-third as much. This lightness comes from an ultra-thin film onto which an extremely thin aluminum coil is etched in a spiral.

This construction eliminates a recurring problem with dynamic drivers: the adhesive required between the coil and diaphragm, which significantly degrades sound quality. In the D7000, since the coil is etched directly onto the diaphragm, no adhesive is involved. This absence of glue, combined with the extreme lightness of the moving assembly, allows the D7000 to reproduce delicate treble with remarkable finesse, revealing details often masked in familiar recordings.

Precise construction and premium materials

The D7000’s housing is machined from an aluminum-magnesium alloy. This machining precision is not mere aesthetics: it is essential to implement the AFDS system, which requires far tighter tolerances compared to conventional planar drivers. The D Series is manufactured at Final’s Kawasaki factory, where assembly precision depends not only on the accuracy of the parts, but also on the assembly jigs. Final designs and manufactures these jigs in-house, allowing fine adjustments to component accuracy variations during assembly.

Dedicated equipment has been developed exclusively for the D Series, including diaphragm molding machines and specialized measuring instruments. This integrated approach ensures that raw materials are transformed in close proximity to the production line, ensuring total quality control.

The washi ear pads are another distinctive feature of the D7000. This traditional Japanese paper stands out for its durability, breathability, moisture management, and antibacterial properties. The headband also uses this material, ensuring high resistance to moisture and wear. The washi’s dry-to-the-touch texture contrasts with typical synthetic materials, providing distinct comfort during long listening sessions.

The D7000 weighs 437 grams, about 86 grams less than the D8000 and D8000 Pro Edition at 523 grams. This 16% weight reduction stems from a global redesign affecting the shells, drivers and their chassis, as well as the headband and earpads. Final remains discreet about the technical details of this weight savings, but the result is immediately noticeable when worn.
