【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[A Game Changer for All Music Lovers: A Super Entry-Level Earphone Offering a High-Quality Sound Experience. Two Types to Choose From Based on Your Needs and Preferences] TRINITY is a super-entry-level concept model newly developed after more than a year of trial and error, aiming for the best sound quality in its class, with the desire to let more people experience a glimpse of the world and sound quality of high-end Hi-Fi wired earphones. TRINITY was named with the aim of becoming a new generation of wired earphones that embodies the tripartite concept of fitting, sound quality, and cost performance. TRINITY comes in two types: a Standard type with a 3.5mm 3-pole L-shaped plug and 120cm cable, and a USB-C type with a USB Type-C plug and a high-sensitivity microphone and 150cm cable. The USB-C type is UAC1.0 compliant, supports 48KHz/16bit playback, and is compatible with Switch/Switch 2 and PS5. [To all music lovers] Experience the vast dynamics of music with TRINITY.
[3-Layer Diaphragm "Advanced ARD Driver"] The driver, which is the key to sound quality, is equipped with an 8mm advanced ARD driver. This is a special dynamic driver with a 46μm thick 3-layer diaphragm structure, in which an ultra-thin PU+PEEK composite diaphragm is sandwiched between two resin layers, and an external magnet that efficiently obtains magnetic force by placing a donut-shaped magnet outside the voice coil. By suppressing partial vibrations, which are difficult to achieve with a typical single-layer diaphragm structure, it enables sound quality with almost no distortion from ultra-low to ultra-high frequencies. The PU+PEEK composite diaphragm offers uniformity, lightness, high-frequency extension, detail enhancement, and reduced nonlinear distortion. The 3-layer structure, in which the diaphragm is sandwiched between two resin layers, achieves optimal internal loss and rigidity. The core thin and lightweight PU+PEEK layer receives vibrations transmitted from the magnetic circuit with as little loss as possible, and in combination with the damping effect of the resin layers before and after it, it achieves flat characteristics across the entire frequency range. By eliminating partial vibrations and suppressing distortion, this technology enables extremely clear reproduction across a wide bandwidth, as well as wide-range reproduction free from frequency response irregularities and phase distortion.
[Class-leading sound image localization achieved through meticulous attention to fundamental performance] TRINITY focuses on the driver, which is the key to sound quality, and has undergone extremely meticulous tuning through repeated trial and error to bring out the driver's performance to the fullest. Distortion is thoroughly eliminated from ultra-low to ultra-high frequencies, resulting in a clear sound with minimal extraneous noise and a high signal-to-noise ratio. The result is a delicate and deep sound achieved by focusing on bringing out the best characteristics of each material. In the low-frequency range, the internal loss has been optimized with the aim of "visible bass" by utilizing the characteristics of the driver, achieving high low-frequency resolution and a sub-bass (ultra-low frequency range) that can be felt. Furthermore, the sound is finished in a way that does not break down even when the volume is turned up, without peaks or distortion. It has also been tested on trains, and the sound has a live feel that is not overpowered by external noise. TRINITY achieves class-leading sound image localization by thoroughly pursuing fundamental performance through resonance suppression with an aluminum housing, ultra-low distortion by suppressing partial vibrations, and optimization of internal loss.
[Includes premium silicone ear tips "SednaEarfit T" with a specially designed shape and a carrying pouch] To improve the fit of the TRINITY, which is not an over-ear in-ear monitor type, and to maximize the signal-to-noise ratio through sound isolation, four sizes (S/MS/M/L *M size pre-installed) of the specially designed ear tips "SednaEarfit T" made from premium silicone by KCC SILICONE are included. The unique tapered fit structure, with a curved umbrella-shaped section that thins towards the tip, reduces pressure on the ear while accurately isolating sound, and the internal horn shape transmits sound from the earphone body directly to the ear. A carrying pouch is also included for portability.
