Description

KZ D-Fi Tuning Version - high-performance flagship dynamic headphones.

Features:

  • 10mm dynamic driver with dual magnets.
  • Full-metal 3D stereo design.
  • 4-position tuning (16 options).
  • Upgraded ear tips.
  • 2-pin gold-plated connector.

KZ D-Fi utilizes an exclusive special amplifier with a dual magnet, dual-driver dynamic driver. Dual magnets mean a double magnetic circuit, the magnetic field of which is strengthened by the overlaying magnetic force of the two magnets, achieving energy efficiency and higher transient characteristics.

Traditional tuning methods are achieved by replacing dampers with different numbers and sizes of cells, but this method cannot precisely control specific frequency ranges. KZ applies innovative PCB tuning methods to accurately control each frequency band according to our target curve.

KZ D-Fi utilizes exclusive patented tuning technology and is equipped with precise electronic switches with 4 positions. The first, second, and third positions are tuned for low frequencies, with each additional position increasing the lower frequency. The fourth position is tuned for the whole frequency range. Users can customize sixteen tuning styles according to their preferences to meet their sound needs.

Most headphones on the market have a frequency response range of only 20 Hz to 20,000 Hz. The frequency response range of KZ D-Fi can range from 7 Hz to 45,000 Hz. Therefore, KZ D-Fi offers deep immersion in the low frequencies and excellent performance.

High-purity silver-plated wire can reduce signal loss during transmission and ensure high-quality sound transmission.

Package Includes:

  • Headphones.
  • Cable.
  • Tuning key.

The lowest frequency, Hz
7
The highest frequency, kHz

The upper limit of the frequencies reproduced by the device. The human ear hears the standard frequency range: 20 Hz – 20000 Hz.

Glossary of terms

Driver type

Most of the headphones are dynamic but there are electrostatic, isodynamic, etc.

Glossary of terms
dynamic

Dynamic drivers use a circuit with a fixed magnetic system, in the gap of which a movable sound coil connected to a diffuser is placed.
