8K SOUND can only be realized when hardware and software are designed in parallel and the two complement each other. In order to realize the full potential of digital signal processing technology, the driver unit must be highly accurate and have extremely low distortion. The ZE8000 features the newly developed "f-CORE for 8K SOUND" ultra-low distortion driver with a large 13mm equivalent* diaphragm, unprecedented for TWS earbuds. A lightweight aluminum-magnesium dome in the center is injection molded onto a highly flexible special silicone surround, and a floating mechanism is used for the CCAW voice coil leads. These designs have resulted in a significantly lighter diaphragm and, because no common adhesive is used, stable piston motion during vibration is achieved. The "f-CORE for 8K SOUND" is said to be the dynamic driver with the lowest THD+N (Total Harmonic Distortion Plus Noise) in wireless earphones and IEMs. This superior physical characteristic of "f-CORE for 8K SOUND" not only provides the highest precision in digital signal processing results but also allows for the fullest possible portrayal of sound texture and detail. * An approximate diameter calculated from the area of the central dome

Conventional sound tuning focuses primarily on altering the frequency response, with little freedom to master the time response. Taking advantage of the computing power of the ZE8000's microprocessor, a series of algorithms using FIR filters were designed and applied to rectify both the frequency and time response. In addition, multiple digital signal processing techniques are applied to each other to enhance the overall system performance and meet the requirements of 8K SOUND.

Furthermore, in addition to the normal "noise canceling mode", it is possible to switch between four patterns: "wind cut mode", "listening while listening mode", and "voice through mode". "Noise Canceling Mode": Reduces ambient noise to make the playback sound easier to hear. This is the default setting. "Wind cut mode": Reduces the "wind blowing sound" noise caused by the wind hitting the microphone of the earphone body, making it easier to hear the playback sound "While listening mode": The music playback volume remains the same , you can hear sounds around you. This eliminates the unnaturalness of loud sounds, such as footsteps, which are supposed to be soft, and is a natural sound capture function that feels less uncomfortable than when you are not wearing earphones. You can enjoy music as background music while checking the surrounding sounds while running or working. "Voice through mode": Automatically lowers the music playback volume to make it easier to hear the surrounding sounds. This is effective when temporarily listening to outside sounds such as train announcements. You can talk without taking off the earphones. *To use it, a software update using the dedicated app "final CONNECT" is required.
