Newly developed 13.2mm dual-cavity planar unit

KZ PR1 is equipped with a new planar unit, the high frequency and ultra-high frequency response is far superior to the traditional balanced armature and dynamic unit. It adopts an ultra-thin silver-plated diaphragm and independent acoustic cavity of the N55 double-sided magnetic circuit array system. This unit brings fast and accurate responses and gentle and transparent sounds.

What is a real planar diaphragm unit?

The planar diaphragm unit differs from the traditional balanced armature and dynamic unit. Its coil is integrated into the thin diaphragm, the permanent magnet is on one or both sides of the diaphragm, and the changing current in the coil drives the diaphragm to vibrate in the magnetic field. Some so-called "planar units" look like planar units in shape, but they still have a traditional coil structure similar to that used in a dynamic unit under the diaphragm. This type of product is not a real planar unit.

What are the advantages of planar earphones?

Because there is no voice coil with substantial weight, the high frequency, and ultra-high frequency of planar earphones are far superior to the balanced armature and dynamic earphones. The coil evenly distributed on the entire diaphragm, combined with the planar magnet array, can distribute the diaphragm's driving force evenly. The motion state of the diaphragm is ideal. It effectively eliminates most of the split vibration and achieves the effect of excellent extension, good transient, and minor distortion.

What is burn-in, and how does it work?

Burn-in is a measure to quickly stabilize the performance of equipment. Burn-in is warming the diaphragm ring. The diaphragm ring of the new earphone has unstable mechanical compliance, resulting in relatively large distortion. After a period of use, compliance gradually changes. Well, the distortion will also drop progressively to normal levels. Of course, the above effect can also be achieved through natural listening, and the burn-in is just a more efficient means for users to choose.
