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.
Through Kinera's proprietary dual acoustic crossover architecture, seamless integration between each sound driver is achieved through both electronic and physical crossovers. Initially, a carefully designed electronic crossover system skillfully controls the frequency cutoff points and slopes to handle sound signals of different frequencies, ensuring that each driver receives the most suitable frequency range. Then, the physical design within the earphone is adjusted according to the characteristics of different drivers, reducing electronic interference between signal transmissions. This allows each driver to focus more on its best frequency range, thereby enhancing the overall clarity and detail representation across all three frequency bands.
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.
The 1+1 composite Sonion dual bone conduction driver used in Hela is one of the most versatile bone conduction units on the market today. Not only does it possess stable transmission performance, but its dual diaphragm co-vibration design also allows for an expansion of the vibration range and frequency of the metal diaphragm, enabling sound to be directly transmitted through the ear cartilage and bones to the auditory nerves. Kinera has also made subtle adjustments to this unit, specifically enhancing its mid to high frequency performance to ensure a very high fidelity transition between the frequency ranges of the balanced armature drivers without compromising the smoothness and comfort of the sound and timbre. These meticulous adjustments not only enhance the focus and sensitivity of the unit but also provide a more realistic and vivid interpretation of the contours and textures of string and woodwind instruments, particularly in terms of transient response and spatial representation, achieving a comprehensive improvement.
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.
The package also includes a black genuine leather case and four different brands of eartips, offering a diverse range of sound configurations:
- Final Type E: Enhances the bass, reduces sibilance.
- AZLA SednaEarfit Crystal: Balanced sound, expansive listening experience, good vocal texture, cohesive bass, clear highs, and excellent adaptability to music.
- Spinfit CP145: Comfortable fit, with excellent elasticity and deep diving bass performance.
- Symbio F Foam: Absorbs treble spikes, enriches the vocals, and provides a thick bass response.
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.
Hela's tuning philosophy specifically emphasizes four major sensory perceptions: atmosphere, crispness, fluctuation, and envelopment. It possesses a high level of fidelity and exceptional detail representation, coupled with a balanced, enduring, and healthy listening experience. Thanks to the assistance of the Sonion bone conduction unit, it maintains a linear and coherent natural connection even under strong sound quality. In the bass range, Hela exhibits outstanding elasticity and deep diving ability. Even under intense beats, the bass remains flexible and agile, with solid drum hits and sufficient extension to enhance the texture of drum skin vibrations and reverberations; it also maintains a good sense of fluctuation in atmospheric jazz music, supporting the bass line to be stable and distinct, with superior layering and diffusion. This is a lively and dense bass performance.
In terms of low-frequency performance, Hela demonstrates excellent elasticity and profound depth. Even in high-intensity percussive music, the bass maintains its flexibility and swift response, with clear drum hits and ample extension, enriching the texture of the beats and echoes. Particularly suitable for listening to atmosphere-rich jazz and live performances, it maintains a stable and clear sense of fluctuation in the bass, with exceptional layering and diffusion, presenting both vibrant and delicate low-frequency effects.
In the midrange, Hela has large sound imaging and dynamic fluctuations, delicately restoring the texture of vocalists and instruments even at low volumes. Each sound maintains sufficient buffer space, keeping the primary and secondary sound focuses distinct and enhancing the depth of the sound field, creating an elliptical stereo envelopment effect. When listening to string music, you will be amazed by Hela's realistic string bouncing and vibrating effects. The mid to high frequencies, supported by the bone conduction unit, maintain the brand's consistent linearity and natural listening sensation, with smooth transitions and brightness, effectively avoiding sound irritation that could arise from overemphasis in specific frequency ranges.
