The Intersection of Ocean Art and Acoustic Technology

The TRN Whale Shark is one of the TRN Marine Series products, inspired by the dominant creature of the vast ocean – the Whale Shark. In terms of appearance, it features a unique hollow design with smooth and dynamic lines. Meanwhile, crystal gems are embedded at the base. When illuminated, these gems radiate a profound and enchanting glow, evoking the mysterious shimmer of light in the deep sea, thereby endowing the design with an elegant temperament.

When the designer first laid eyes on the hand-drawn sketch of the whale shark, inspiration surged like a tidal wave — this gentle giant of the ocean is both a ruler of the deep and a walking work of art. Subtle, thoughtful touches are hidden in the details: the hollowed-out design on the outer faceplate of the TRN Whale Shark draws inspiration from the arrangement of dermal denticles (placoid scales) on the whale shark's skin. These tiny scales reduce water resistance, and the designer transformed them into a highly distinctive decorative element.

This design choice not only echoes biological features but also presents a delicate touch through matte coating technology. With TRN Whale Shark, we never intended to replicate a marine creature — instead, we sought to capture the qualities that resonate deeply with human perception. As the designer wrote in their notes, “When users wear it, we hope they feel not just a pair of earphones but the breath of the ocean, the flow of life, and the romance of nature and technology coexisting.”

Three Dynamic Drivers + One Planar Magnetic Driver

Delivering uncompromising fidelity to every sound

The TRN Whale Shark is equipped with a premium configuration of three dynamic drivers and one planar magnetic driver on each side. Considering the distinct acoustic characteristics of these two types of drivers across different frequency ranges, our engineers conducted continuous adjustments and experiments to integrate them into a unified four-driver matrix acoustic architecture.

Through fine-tuning and precise control of the frequency response of each unit, TRN Whale Shark achieves an overall balance, stronger sound hierarchy and depth, and a smoother connection between frequency bands. The result is a more comprehensive auditory experience — every melody feels full of emotion, every note resonates like the deep sea, delivering pure sound quality that shocks the aural world.

Patented Three Dynamic Driver Acoustic Architecture

Second-generation full-size beryllium-plated composite diaphragm

The TRN Whale Shark utilizes a three-dynamic driver acoustic architecture to ensure pure and accurate sound reproduction. The low frequencies are powered by a second-generation 10.5mm full-size beryllium-plated composite diaphragm driver, an 8mm PET diaphragm driver handles the mid-high range, and the high frequencies are delivered by a 6mm titanium-plated diaphragm driver.

These advanced diaphragms combine lightweight construction, high strength, and excellent vibration characteristics. The result is extended frequency response, exceptional rigidity, and low-density performance. Each driver is optimized for its frequency range, providing superior separation, precise spatial imaging, and a natural sense of presence.

With TRN Whale Shark, listeners can enjoy a rich, immersive "deep-sea sound" experience — from the energy of pop tracks to the refinement of classical music — always with faithful and engaging sonic reproduction.

6mm Planar Magnetic Driver

Exceptionally smooth and natural detail reproduction

The TRN Whale Shark incorporates a 6mm planar magnetic driver capable of extending into the highest frequency ranges with low distortion, broad bandwidth, and smooth response. It has a natural advantage in reproducing ultra-high-frequency tones and fine details.

Through rational power distribution and synergy with the three dynamic drivers, TRN Whale Shark achieves precise and clear reproduction of the highest frequencies. Thanks to its unique vibration pattern and frequency response, the planar driver responds rapidly and accurately, capturing subtle nuances with precision.

Compared to other driver types, it is also easier to drive, significantly lowering the barrier to powering the earphones. With this design, the ultra-high-frequency range is meticulously rendered, resulting in a more natural, authentic, and engaging listening experience.

Triple-driver Core Technology

Ensuring every sound element performs with precision

The TRN Whale Shark adopts a hybrid driver architecture with three dynamic drivers and one planar magnetic driver, combined with core triple-frequency division technology. This "triple-frequency division" goes beyond a simple split into three frequency bands.

It relies on professional-grade acoustic tuning algorithms and optimized crossover networks to ensure each driver handles only its specialized frequency range. At the same time, transitions at overlapping intervals remain smooth and natural. Through careful allocation and expert calibration, TRN Whale Shark delivers a balanced, detail-rich, and immersive listening experience across the entire spectrum.

Unleash The Power Of Triple Dynamic + Planar Drivers

Capturing every nuance of sound without leakage

The TRN Whale Shark features a novel driver configuration with three dynamic units and one planar magnetic driver, combined with a rigorous acoustic design. Its final sound profile was refined through extensive listening tests by multiple acoustic engineers. After several stages of acoustic tuning, TRN Whale Shark fully unleashes the potential of this architecture, delivering a natural, expansive, and detailed tonality with high-fidelity reproduction. It maintains ultra-low distortion even during passages with a wide dynamic range, offering stronger bass extension and enhanced atmospheric immersion.

In addition, the earphones are equipped with three adjustable sound style tuning nozzles, easily replaceable thanks to a threaded quick-release structure. Each nozzle contains different filters that create unique tuning effects, unlocking more possibilities and allowing listeners to experience music with greater richness and authenticity.

Ultra-low nonlinear distortion is attributed to excellent craftsmanship and a rational driver structure. The high-quality diaphragm material enables the TRN Whale Shark to achieve nonlinear distortion below 1% across nearly the entire frequency range, resulting in a profound sense of tonal stability and accuracy.

Crystal Gemstone Art Hollow Design

Exquisite acoustic treasure

The surface of the TRN Whale Shark features a hollow art design, with each line replicating the unique texture of whale shark skin in smooth and dynamic curves. This carefully calculated structure not only reduces the burden of wearing but also gives sound wave transmission a natural, flowing rhythm.

At the base, a sapphire crystal serves as the finishing touch of the deep sea. Under illumination, it radiates a brilliant luster that enhances the earphones’ texture while adding a subtle, mysterious temperament.

Standard High-Quality Single-Ended Cable

Oxygen-free copper and silver-plated single crystal copper hybrid

The TRN Whale Shark comes standard with a premium hybrid cable, crafted from oxygen-free copper, silver-plated wire, and single-crystal copper braided together in a precise ratio. This dual-strand structure features 500 cores per strand, combining the advantages of both materials. The result is enhanced high-frequency response, reduced signal distortion, and reliable high-fidelity transmission.

Thanks to the Litz hybrid design, the cable delivers improved separation and clarity, offering more transparent and detailed audio. It also uses a 0.78mm 2-pin interchangeable connector, allowing users to upgrade or adapt the cable for different listening scenarios with ease.
