D-Fi adopts the exclusive custom dual-magnet & dual-cavity dynamic driver. Dual magnetic what it means dual magnetic circuit, whose magnetic field is enhanced by superimposing the magnetic force of 2 magnets, which to achieve energy efficiency and stronger transient performance.


Pioneering and innovative precise tuning method

The traditional tuning method is achieved by replacing dampers with different mesh numbers and sizes, but this method cannot accurately control a certain frequency band. KZ adopts innovative circuit board adjustment methods, which can accurately control each frequency band according to our target curve.

Two versions available

Meet the individual needs of different music lovers

D-Fi is designed with a standard version and a tunable version. Standard versionhas an accurate and balanced frequency responsetuning. Tunableversion can achieve 16 different sound styles by adjusting the toggle switch to meet the different needs of more players.Precision four-gear switches

Sixteen tuning styles

D-Fi adopts exclusive patented tuning technology and is equipped with precise 4 gear electronic switches. The first, second, and third gears are adjusted for low frequencies, and each additional gear increases the lower frequency. The fourth gear is adjusted for the full frequency band. Users can customize and adjust sixteen tuning styles according to their personal preferences to meet their individual needs for sound.Suitable for a variety of music styles, easy to drive

The bass is strong properly & clear, plus the natural & smooth sub bass, treble well-defined, which makes D-Fi becomes one of the dynamic king in the market.

Outstanding parameters bringoutstanding sound quality

Frequency response range is an important parameter for judging the sound quality of anearphone. Most earphones on the market have a frequency response width range of only between 20Hz and 20000Hz. The frequency response width of D-Fi can range from 7Hz to 45000Hz. Therefore, D-Fi has deep enough low-frequency diving and excellent high-frequency performance.Creative irregular faceplate design

The engaging metal texture is created through multiple processes, andthe mirror effect is achieved after manual mirror polishing. Through the above process, to create high-end IEM.Focus on ergonomic in-ear designfor cavity & nozzle

Comfortable to wear it

The properly length nozzle, with the ergonomic cavity design, which ensure the earphone comfortable to wear and not easy to fall off. Meanwhile, D-Fi adopts the sound-isolating memory foam eartips to effectively reduce external noise interferenceProfessional high-purity silver-plated cable

High purity silver-plated wire can reduce signal loss during transmission and ensure high fidelity transmission of sound.Control all function in one button (only for the cable which with microphone)
