Delicate and compact industrial style

Like its name, KZ Ling Long adopts a minimalist aesthetic design, and the earphone chamber is made of pure aluminum alloy. Its net weight is only 18g, and it can be worn in various ways.

Professional open-back cavity acoustic design

Wider sound field
The precise cavity structure can control the airflow to enhance the dynamic performance of low frequency. At the same time, it can also make the voice sweet and warm, retain more details of the instrument, and form a clean and balanced sound.
The traditional pressure relief structure
The traditional structure
The traditional pressure relief structure adjusts the chamber's internal pressure through the pressure relief hole to avoid damaging the diaphragm when the chamber's internal pressure is too high, and it helps weaken some low-frequency output. Still, this practice will distort the overall sound quality.
Open-back design
Open-back design
On KZ Ling Long, we optimized the new magnetic circuit structure on the XUN-6 unit. Also, we adopted an open-back chamber design, which significantly increased the air flux and flow rate, making the hearing more transparent and natural.

Amazing professional tuning

Small size hides incredible energy
Compared with the conventional-size dynamic unit, the micro-dynamic unit has an inherent structural advantage in high-frequency performance. It is easier for the micro-dynamic unit to show the UHF details vividly.
KZ Ling Long Frequency Response
KZ Acoustics Laboratory measured the above data.
Actual use may be slightly different depending on the specific situation.

Ingenious design

Good-looking and practical
The small and light shape also effectively reduces the pain of wearing in-ear earphones, and smaller sizes can be more deeply inserted into the ear canal. The high-frequency attenuation is negligible when the nozzle is closer to the eardrum.

Simple, practical, and environment-friendly packaging, it has been used for 10 years

We believe that products do not need to be packaged in luxury because the actual performance of products can not be presented in packaging. We advocate environmental protection, but we will not make high profits in the name of environmentalism, which has been one of the beliefs of KZ since its founding.
