Designed for the depths of the ocean
The dynamic protrusion on the TRN Dolphin earphone cover is not a decoration. Still, a tribute — it reproduces the smooth curvature of a dolphin's head breaking through waves, transforming water resistance into a comfortable fit on the ear.
The liquid-metal chamber has undergone dozens of curved polishing processes, achieving a symbiosis between "rigidity" and "softness."
The metallic texture provides acoustic stability, while the streamlined contour makes it feel like a fin attached to the ear. Stable as a dolphin swimming in motion, hidden quietly in silence.
The resonance of sound
Listening is another form of wandering
In the vast ocean, dolphins are elegant creatures and wise singers. They break through waves with streamlined bodies, perceive the world through high-frequency sonar, and weave intangible melodies in the deep blue. TRN Dolphin earphones embody the beauty of life in every detail, dedicated to every soul that desires free listening.
Transient as a leaping dolphin, effortlessly controlled
Precision captures every musical wave
TRN Dolphin employs a high-molecular-weight LCP (Liquid Crystal Polymer) diaphragm, delivering exceptional “high-resolution” sound that faithfully reproduces every intricate detail in music. Much like a dolphin’s sonar precisely locating its target, the LCP material maintains high rigidity while achieving lightweight thinness, enabling lightning-fast transient response. Like a dolphin leaping from the sea, it brings agility and decisiveness, infusing music with vitality and rhythm.
Second-generation 10mm dual magnetic dual cavity
Experience the immersive sound of a large dynamic driver
The TRN Dolphin features a second-generation 10mm large dynamic driver with a larger diaphragm area that moves more air, delivering powerful bass with a solid sonic foundation for a natural, spacious listening experience. Just as dolphins require robust physiques to navigate the deep sea, the doubled magnetic flux enhances energy conversion efficiency and improves driving control. This results in rapid sound response and more powerful dynamics. It excels at reproducing contrasts in musical intensity (dynamic range), making the grandeur of symphonies or the impact of electronic music even more awe-inspiring.
Upgraded acoustic structure
Delivers natural, seamless sound across all three frequency bands
A well-structured acoustic cavity acts as a natural “physical tuner.” It regulates airflow, ensuring seamless transitions between the three frequency bands (high, mid, low) as fluidly as a dolphin gliding through water, preventing abrupt peaks or dips in certain ranges. These unwanted vibrations act like echo interference in a concert hall, obscuring details and muddying the sound.
Through extensive calculations and specialized materials, TRN Dolphin features a new acoustic cavity that effectively absorbs and dissipates harmful standing waves and resonances.
Outline the curve of emotional tone
The melodious voice of professional tuning
Based on scientific data, professional sound engineers perform curve tuning, integrating human listening preferences and musical emotional expression to achieve precise fine-tuning. The sound details are delicate, capturing every subtle breath and nuance of the singer, allowing the music to reach straight into the heart. With TRN Dolphin, every note resonates with clarity and emotion.

Scientific optimization of frequency response
Achieving native low distortion
This scheme is based on standard acoustic curves and scientifically optimizes and compensates for earphones' full frequency response using precise algorithms. It significantly reduces harmonic and intermodulation distortion at the source, achieving native low-distortion performance. TRN Dolphin achieves energy balance across all frequency bands, delivering precise and natural sound reproduction.

Liquid metal chamber
Creating a pure space for sound
TRN Dolphin adopts a liquid metal cavity design with high rigidity and premium materials, effectively suppressing cavity resonance and vibration. When the unit is operating, the cavity itself generates minimal unwanted resonance, avoiding “sound distortion” and ensuring purity and accuracy. A quiet acoustic space allows every note to be presented clearly without interference.
Upgrade the cable to elevate sound quality
Replaceable plug on demand
TRN Dolphin is paired with a high-purity silver-plated oxygen-free copper upgrade cable. Oxygen-free copper features low resistivity and excellent conductivity, effectively reducing signal loss and distortion during transmission. The silver-plated layer further enhances high-frequency transmission efficiency, making the sound more detailed and the high-frequency extension more natural. This cable combination helps preserve the original character of the music and avoid sound quality degradation caused by cable issues.

0.78 2-Pin plug
3.5mm/4.4mm/Type-C plug, comes standard with one. Different plug styles can be selected based on specific needs.
Wear around the ear
Build a silent barrier for music
The TRN Dolphin features an over-ear cable design that forms a stable support around the upper part of the auricle. The ear tips are available in various sizes to ensure a secure fit and prevent detachment. Whether during intense exercise, outdoor running, or daily commuting, the earphones fit snugly, allowing users to focus fully on music and movement. A well-designed ear wrap structure distributes weight across multiple support points on the ear, reducing pressure at the ear canal opening. It is especially suitable for users with sensitive ear canals, delivering true “pressure-free wearing” and long-term comfort.
Rich accessories
Meet the needs of multiple scenarios
TRN Dolphin comes standard with two strands of silver-plated oxygen-free copper cable and four pairs of ear tips in different types and sizes: T-tips *1 (M) and Balanced tips *3 (S, M, L). It supports 3.5mm, 4.4mm, and Type-C connectors (optional), thoughtfully designed for hassle-free use.
