High-power driver with powerful dual-circuit

TRN Conch is equipped with a dual-circuit design to optimize magnetic flow, ensuring the magnetic and thermal stability of the driver unit under high load, thereby reducing harmonic distortion, improving the resolution and clarity of the sound, and at the same time, providing the sounding unit with a more abundant and powerful driving force, making the music more realistic and stereoscopic, providing a purer listening experience for music lovers.

Good diaphragm, good sound

DLC diamond composite diaphragm
To achieve better sound quality, the TRN Conch uses a DLC diamond composite diaphragm. This diaphragm combines a high-resistance substrate with a nano-thin layer of DLC amorphous carbon. The resulting diaphragm has excellent electroacoustic performance, which effectively reduces the splitting vibration of the loudspeaker diaphragm, reduces audio distortion, and improves the extension and resolution of high frequencies. The result is a purer sound quality.

Multifaceted audio

Interchangeable tuning nozzle filters
TRN Conch comes with three interchangeable nozzle filters that can be used to change the sound style. The filter inner diameter size and filter net are different, which strengthens different audio areas.

Immersive sound world

Optimized delicate sound cavity structure
To achieve better sound quality and soundstage reproduction, we have carefully optimized the sound cavity of the earphone.The ingenious design of the sound cavity structure and volume, in combination with the acoustically stable liquid metal outer cavity, controls the reflection of excess noise. The air holes in the front cavity bring in more air volume while finely controlling the airflow in conjunction with the high-performance DLC diamond diaphragm dynamic unit to output pure and natural sound.

Liquid metal cavity

Precisely engineered design
The outer appearance adopts a liquid metal cavity design, processed through multiple complex procedures. It has not only a high-strength and durable body but also a finely uneven surface in the cavity that can effectively print standing waves, providing a purer sound. In addition, the mirror electroplating process is simple but not lacking a sense of modernity. It not only has excellent durability but also has the temperament of a work of art, enjoying a high-quality aesthetic experience.

Stable ear-hook design

Lightweight wearing experience and extraordinary texture
The "conch" shape optimizes the contact area between the earphone cavity and the skin of the ear canal. The ear-hook design fits more closely to the shape of the ear canal and provides more stable support when worn. It is comfortable to wear for a long time, and you can listen to Hi-Fi sound with peace of mind.

Standard audiophile-grade cable with swappable connectors

Gold-plated 2Pin connectors
TRN Conch adopts a 4-core silver-plated copper wounded and oxygen-free copper braided cable. Such configuration has the advantages of both silver-plated copper and oxygen-free copper. It effectively gives fullness to the sound. Resolution is greatly enhanced, extracting fine details with unsurpassed clarity.
