TONALITE

New flagship model that meets all functions

TONALITE isfinalAs a new flagship model, it combines unprecedented ultra-high sound quality and the highest level of noise canceling performance.

In order to achieve high ANC functionality, it is equipped with SONY's highest class ANC dedicated chip "CXD3784" *1. On top of that, by introducing the ultra-low distortion technology cultivated in the flagship wired earphone model "A10000," we have achieved sound quality that surpasses even high-end wired earphones.
Furthermore, the world's first *2 personalization technology "DTAS" is adopted. By scanning your body with an app and creating sounds that match your body shape, you can now directly experience ultra-high quality playback sound.

*2...As of October 31, 2025, according to our research. The results of a survey of TWS manufactured by major domestic and foreign brands to determine whether there are products whose main purpose is to apply individualized tones.

A completely new experience with new personalization technology “DTAS”

The new personalized technology ``DTAS'' brings not only dramatic tonal reproducibility. It's a completely new feeling that can't be measured by how good or bad the sound quality is. Dramatically update your music experience itself.

What is noteworthy is the overwhelming sense of reality of the "human voice." Human ears have evolved to hear human voices. That's why we paid particular attention to its reproducibility. Its smoothness and vividness breathe life into all voice-centered content, including music, radio, podcasts, anime, movies, and more.
"I can't believe Oshi's voice sounds so good..." Some people expressed surprise at the audition.

We have received many other positive comments, such as, ``It's a strange feeling that the sound has a sense of definition even though there is no piercing or noisy sound at all,'' and ``I was surprised by the localization, which made the vocals appear right in front of my eyes, but I was surprised again when I heard that this was due to correcting the difference in the shape of my left and right ears.''

The sound produced by DTAS is such an overwhelming music experience that once you listen to it, you will never go back to other earphones.

Equipped with triple hybrid noise canceling

The nested housing ensures a highly airtight acoustic space, while the unique inner vent mechanism optimizes air pressure.
In addition to these physical sound insulation properties, we have adopted a triple hybrid method that combines feedforward and feedback methods. Furthermore, we use SONY's ANC dedicated chip "CXD3784"* and Infineon's high-performance MEMS microphone,finalA unique algorithm achieves silence without any oppressive feeling.

In addition, for noise canceling, you can select "Sound Quality Priority" or "ANC Priority" in the in-app settings. If you select "Sound Quality Priority" mode, you can enjoy music in a quiet environment without affecting the sound quality at all.

Equipped with ultra-low distortion driver "f-CORE for DTAS"

We have generously applied our unique distortion reduction technology cultivated through the development of the wired flagship model "A10000."
By integrating the diaphragm and the edge using injection molding, there is no need for adhesive itself, achieving a thorough weight reduction and uniform weight balance. Furthermore, "air wiring" is used for the coil drawer to reduce adhesive and maximize drive accuracy.
As a result, the distortion rate has been dramatically reduced as shown in the figure below. Especially the reproducibility in the low range below 200Hz is amazing. The bass line and drum kicks do not feel crowded, and even the minute scales of the bass are easily understood, achieving a detailed and overwhelming bass expression.

Ambient mode that can be used even in quiet environments

Generally, when using the earphone's ambient mode in a quiet environment such as a library, some people have complained that the sound of keyboards and footsteps can be distracting. A unique algorithm suppresses the emphasis on specific sounds, creating an ambient mode that can be used even in quiet environments.

Excellent fit and comfort

Large parts such as the battery and circuit board are placed on the outside of the housing (the part that extends outside the ear), making the part that is inserted into the ear as small as possible. As a result, even people with small ears can wear it comfortably without feeling pressured.

Furthermore, the earpieces are made of FUSION-G, which combines the flexibility of silicone and the sound insulation properties of foam. While maintaining high sound insulation performance, it is also comfortable to wear even after long periods of use.

Long battery specifications of up to 9 hours

In order to achieve ultra-high sound quality, the internal chip performs advanced signal processing. Although this process requires more power than usual, by carefully adjusting and optimizing battery control, we have achieved a long battery life of up to 9 hours with the earphones and up to 27 hours with the charging case included.

Grain finish that resists fingerprints

A grain finish with finer grain than usual by layering matte and gloss. It is resistant to fingerprints and dirt and has excellent durability.

Mechanism of tone personalization using unique simulation technology “DTAS”

The shape of the human body -- the size of the head, the shape of the ears, the thickness of the shoulders -- changes the sound that reaches the ears. The body shape varies greatly from person to person. However, since earphones deliver sound without taking into account the influence of body shape, the impression that each person receives when listening to sound differs from person to person.
TONALITE is the world's first* earphone that measures the individuality of the body and personalizes the tone (applies individuality).

What is the tone personalization brought about by DTAS?

When ``natural tones'' are realized through tone personalization, you will be able to hear delicate sounds and intonations that you have not noticed before, even in songs you have listened to many times, and the image of the sound you get will completely change. As a result, I keep getting curious, "How will this song sound?"

The results produced by DTAS are, so to speak, a blank canvas. The colors (tones) drawn there stand out clearly against the white background, allowing you to see even the finest touches.
If this canvas itself becomes cloudy, the drawn lines (sound) will become difficult to see.

Numerous studies have shown that the naturalness of the timbre is more important than the spatial impression when enjoying audio content. For example, the graph below shows the number of comments categorized regarding sound during playback experiments of VR (Virtual Reality) content. Even in VR content where spatial reproducibility is often thought to be important, it can be seen that timbre is the most dominant, and sense of space is second. [1]

A new world of EQ opened up by DTAS

Conventional earphones did not take into account the influence of individual body shapes, so there were differences in how people heard sound when wearing them. In order to use an EQ (equalizer) to adjust the sound to my liking, I had to make extremely difficult adjustments to get the sound closer to the ideal while correcting the difference between the earphone's target curve and the influence of my own body shape.

finalThe R&D team believes that in order to create an ``immersive experience'' where there is no difference between the sound of the earphones and the real world, it is essential to first thoroughly improve the physical characteristics of the earphones and eliminate the effects of body shape. I am confident that only then will a world in which each individual can pursue their own preferences expand.

This time, TONALITE has succeeded in creating a natural tone base that takes into account the influence of body shape using "DTAS" technology. Because of this foundation, you can experience a completely new world of sound by adjusting the EQ.

In fact, I often hear people say, ``I've tried adjusting the EQ many times, but in the end I don't use it much anymore.'' However, if you operate the EQ after setting up DTAS Personalized, you will be surprised to find that no matter where you make the adjustments, you will be able to make the adjustments as intended and that they will suit your tastes.

Additionally, until now, even if you found your favorite EQ settings, it was theoretically impossible for someone else to hear the same sound with the same settings due to differences in body shape. However, with personalized TONALITE, you can share the EQ settings with your friends and share the exact same sound with excitement.
