Hela's technical and structural design is not simply about "stacking the number of drivers." Based on the parameters of past hybrid driver models, the "1642" hybrid array with thirteen drivers is constructed. For the low frequencies, a 6mm liquid crystal polymer dynamic driver exclusively designed by Kinera is used to ensure depth and richness in the bass. For the mid to upper mid frequencies, a custom "4+2" Knowles balanced armature driver configuration is carefully arranged to enhance the naturalness and smoothness from the mid to high frequencies.

Additionally, four Sonion electrostatic drivers responsible for the ultra-high frequency range serve as the core of the sound output. Paired with a metal sound nozzle design, this setup allows better control of sound wave propagation, achieving a wider high-frequency extension and significantly enhancing detail representation, while maintaining an appropriate level of brightness and softness. Moreover, the specially added 1+1 composite Sonion dual bone conduction unit enriches the tonal layers of the mid to high frequencies, ensuring smooth integration across Hela's high, mid, and low frequencies. Combined with Kinera's consistent balanced and refined tuning approach, the Hela comprehensively display an overwhelming "queenly presence," achieving a super flagship-level pinnacle in terms of sound completion and quality.

Leveraging over a decade of profound expertise and extensive development experience in acoustic design, material science, and electroacoustic engineering, a new generation 6mm liquid crystal polymer diaphragm dynamic driver was selected for Hela. This diaphragm assembly significantly strengthens both the mass and damping of the membrane, effectively reducing unnecessary resonance. This expansion of the frequency response range and significant distortion reduction are achieved through these enhancements. The magnet component uses a high-precision, fully enclosed layout, which enhances the strength and uniformity of the magnetic field. This fortified magnetic field provides a more stable and uniform operating environment for the coil, increases the magnetic flux, and improves the magnetic conductivity.

Consequently, this significantly enhances the stability of the sound chamber and greatly boosts the acoustic performance of the dynamic driver unit, ensuring that the bass remains rich with excellent elasticity and a relaxed, natural dynamic response.

Through the meticulously designed Hela, from the faceplate to the outer shell, each piece is hand-painted stroke by stroke by seasoned designers and painters. Utilizing an exclusive "multi-layer hand painting technique" that incorporates high-quality pigments and 3D printing technology, this method allows for a collision of colors that create rich layered effects and gradient patterns. Drawing inspiration from the image and personality of Hela, the shell and faceplate are primarily in deep starry night blue, with the addition of flame stripes on the faceplate symbolizing the fires of the underworld, and further embellished with sparkling silver foil. The vivid colors are filled with natural tension, and each pair of Hela faceplates features a unique texture that reflects a depth and mystery akin to the underworld.

Furthermore, the earphone cavity is manufactured using high-precision 3D printing technology. Based on Kinera's extensive database and ergonomic design, the earphone shell perfectly fits most users' ears, offering a custom-fit feel. The pressure relief holes at the bottom of the cavity are designed to effectively balance the pressure inside and outside the ear canal, eliminating the sensation of ear pressure caused by long-term wear, thereby greatly enhancing comfort.

Kinera, taking into account the tuning preferences and listening habits of users in the Hong Kong region, also includes a Hong Kong-exclusive cable made by the Singaporean cable brand Eletech, named Victoria. This cable employs a flagship 9x9 geometric braiding configuration, complemented by a quad-twist 26 AWG high-purity single crystal copper + single crystal copper gold-plated core, further enhanced with a copper-silver plated shielding mesh. Paired with Hela, it provides a clear and warm vocal presentation, increases the richness and moistness of the mid and low frequencies, significantly enhances high-frequency details, and offers a quiet musical background, optimizing the sound potential of Hela to its fullest.
