NUARL to Launch World's First 2x2 Sound Technology Completely wireless earphones "Inovator" to be released in December 2024

MTI Corporation (Location: Toshima-ku, Tokyo; Representative Director: Keijie Chang) announces that it will release the world's first (according to its own research) fully wireless earphones with "2x2 Sound Technology", "Inovator "*, from its original brand "NUARL" in December 2024. Inovator" earphones will go on sale in December 2024.

Inovator" is officially written with an umlaut over the letter "o

Inovator (1)

The world's first "2x2 Sound" technology

The dual-driver configuration with two drivers for high and low frequencies does not use a physical network element, but uses a bi-amplifier drive system that independently controls each driver using a separate amplifier (DAC), similar to that used in high-end home-use audio systems. The earphones are designed with a conventional hybrid driver configuration. This is the world's first technology for fully wireless earphones that eliminates crossover distortion and adverse effects on sound quality that conventional earphones with hybrid driver configurations have, and also enables more detailed adjustment of sound quality for each driver.

MEMS speaker

MEMS speakers, which boast ultra-high frequency reproduction capability of over 100KHz, low distortion, and high precision, are employed for the high frequency range. Compared to the BA driver used in conventional hybrid configurations, the MEMS driver has superior phase characteristics and reproduces a more delicate ultra-wide frequency range.

NUARL's unique dynamic driver

The dynamic driver combined with the MEMS speaker is the newly developed NUARL DRIVER [N8]v4, which uses a φ8mm LCP (liquid crystal polymer) diaphragm. Despite its small diameter, it delivers excellent low-frequency reproduction capability required for active noise cancellation.

■Built-in metal earphones

The dynamic driver and MEMS speaker are combined on the same sound axis to prevent phase shift that can easily occur in multi-driver configurations. Furthermore, by enclosing them in a forged aluminum alloy housing and mounting them in analog-tuned wired earphones, unnecessary resonance is suppressed and clear sound is achieved.

Housing formed with medical grade resin

The complex shape of the housing was derived from a simulation based on the ear mold database of an earphone housing manufacturing company that produces a variety of custom IEMs, and the 3D printing process was used to create the housing. The housing is made of medical grade resin that is gentle to the skin and provides both a lightweight fit and high sound insulation.

Audiodo(TM) Personal Sound" sound personalization function

Audiodo(TM) Personal Sound" optimizes sound quality according to the user's hearing. Sound quality is optimized to maximize the acoustic properties of Inovator according to the hearing characteristics measured using the "NUARL do "*1 smartphone application. Instead of lifting frequency bands that are difficult to hear as in general hearing correction technology, the reproduced sound is corrected using a proprietary algorithm so that the original sound quality of the product being used is perceived correctly. In addition, the system dynamically compensates for hearing differences between left and right ear and for changes in hearing caused by volume, thus achieving more effective correction of hearing characteristics than conventional sound quality correction technologies. In addition, the corrected personalized characteristics are stored in the earphones so that playback sound quality is always optimized even if the music playback software or hardware is changed.

Audiodo Equalizer" supervised by Carl Falk

Audiodo Equalizer" supervised by Carl Falk, who has provided music for One Direction, Ariana Grande, and many other musicians. The interface is more intuitive to use than conventional equalizers, and in addition to auditory correction by audiodo, it is possible to adjust tones according to your preferences.

■Consideration for acoustic hearing loss

The "Safe Listening" function, an optional feature of "audiodo(TM)," is supported. This function limits the volume to prevent hearing damage caused by prolonged use at excessive volume levels.

■Immersive audio function

Regardless of the content format, the immersive audio function reproduces the natural sound expansion of any sound source, including music and movies, and reproduces a three-dimensional sound field like that of a live performance. (This function will be added in a firmware update at a later date.)

HDSS(R) for more accurate sound

HDSS(R)" is a patented technology developed by T.B.I. of the U.S. that suppresses distortion caused by physical phenomena inside the earphone housing to achieve more accurate sound reproduction in response to input signals. The HDSS(R) technology prevents in-head localization, which is common in canal-type earphones, and reproduces natural sound with depth and a sense of three-dimensionality.

Hi-Res Wireless support

Supports the high-quality sound wireless codecs "LAC*2" and "aptX Adaptive (96K/24Bit)". LC-3*2, aptX Lossless and AAC codecs are also supported.

■Hybrid Noise Cancellation

Hybrid active noise cancellation combining feed-forward and feedback is provided. Mode switching and intensity adjustment via an app are also possible.

■Call noise cancellation*3

The 3-microphone cVc (Clear Voice Capture) technology is used for call noise canceling. It eliminates ambient noise during calls and provides clear voice transmission to the person on the other end of the line.

Smartphone operation*4

The NUARL do app can be used to customize settings.

Low latency mode

A low-latency "gaming mode" is available by using the NUARL do app. Low latency wireless communication is available regardless of the device being used, such as a PC or game console. *5

Optimized balance between sound quality and comfort

Two types of earpieces are included: "Magic Ear+7" low-resilience foam earpieces that provide both comfort and sound insulation, and "Block Ear+6N" earpieces made of antibacterial silicone. It is possible to optimize the wearing comfort and sound insulation to suit your preference. *6

Dedicated application "NUARL do

The dedicated "NUARL do" application, available for iOS and Android devices, allows users to set Audiodo functions, expand Inovator functions, and update firmware. When using a multipoint connection, the app can also be operated on the side of a connected device other than the device listening to music, making it convenient for use with DAPs. *1

Color variations limited to 200 units

The "White Porcelain" color variation features a pattern inspired by "white porcelain" pottery on the top cover of the earphones. The random patterns created by the handmade process expresses originality, with no two patterns being the same. This is a limited production model of 200 units worldwide.
