Final ZE2000 True Wireless Earbuds with ANC, Hi-Fi Sound & 30H Playtime - Perfect for Gym, Commuting & Travel

Equipped with a newly designed driver "f-Core for Wireless" that achieves ultra-low distortion
Excellent audio equipment, amplifiers and other electronic equipment have an extremely low distortion of about 0.0001%. On the other hand, the distortion generated by the driver unit (speaker part) inside the earphone is 1% or more in the low range even with excellent products. In other words, it can be said that a distortion of 10,000 times or more is generated in the process of converting the electrical signal into sound in the driver unit (speaker part) of the earphone. If this distortion can be greatly reduced, sound quality will improve dramatically. In addition, true wireless earphones often rely heavily on software equalizers to adjust the sound quality, and as a result, the sound quality tends to be easy to get tired of listening to. With the ZE2000, the basic performance of the driver unit has been enhanced, and acoustic sound quality adjustment using the acoustic space inside the housing of the earphone has been adjusted so that the sound quality can be fully satisfied without an equalizer. On top of that, we perform extremely effective correction that only an equalizer can do, such as reducing the sound pressure in a narrow band with pinpoint accuracy. However, in order to make effective use of this equalizer adjustment, a driver unit with extremely high precision sound pressure frequency characteristics is required. If there is a variation of about 3 dB, which is a general accuracy, correcting with an equalizer will rather produce unnatural results.

"f-LINK damping mechanism" that optimizes the internal pressure of the housing
Completely wireless earphones require a high density of batteries, electronic boards, antennas, etc. As a result, the degree of freedom to adjust the sound quality by acoustic means is low, and we have no choice but to create sounds under strict constraints. In addition, since waterproof performance is required for completely wireless earphones, vents (vents) that optimize the pressure of the acoustic space inside the earphone housing cannot be opened outside the housing. As a result, typical true wireless earphones without vents have too much low end and are forced to emphasize high end to balance it out. As a result, not only does it create a flashy sound that emphasizes both the low and high frequencies, but it also tends to lose its naturalness, such as vocals becoming distant. 

The ZE2000 is equipped with a newly developed "f-LINK damping mechanism" that optimizes the pressure in the acoustic space inside the housing of the earphone and enables an acoustic design equivalent to that of wired earphones without venting to the outside of the housing. I'm here. This makes it possible to properly control the low range, which was difficult to achieve with the sound quality design of a completely wireless earphone, and reproduce vocals that tend to be far away with the balance intended by the artist. In addition, the low-frequency reproduction of drum kicks and bass lines, combined with the ultra-low distortion of the driver unit, achieves a high quality that allows you to feel the subtle dynamics in the bass.
