12 Balanced Armatures HiFi In Ear Monitor

With the strongest hardware configuration, L12 features 12 drivers each side which is quite a classic and reasonable number of drivers with excellent performance and perfect frequency division. Well acclaimed Sonion and Knowles drivers combination guarantees satisfying sound quality and it indeed reaches the peak of the current driver technology.



In the field of pure moving iron earphones, we believe that the 12-driver is close to the limit of sound quality. With the ergonomic cavity structure, it is difficult to increase the quality by adding more drivers. L12's tuning design philosophy is to return to the basics. In reaching this level of sound, quality is not the only goal pursued. It should be able to handle any music interpretation with ease and leisurely walks. In the tuning design, we make the sound of L12 more emotional, rather than fiercely compelling. The introverted and moist listening, accurate driver voice connection, and unhurried sound style will let you return to the music itself, rather than cold. The parameters and data-based blunt auditory effects. Gentle and melodious is the core of the L12's sound. The sound quality is high enough, detailed and orderly, suitable for fans who want to return to the music itself, low-key and luxurious sound.


Ergonomic Shape

When it comes to the appearance, Leisurely audio will never let you down with their extraordinary aesthetic. L12 is also designed with ergonomic technology to better fit human ear canals. It can greatly isolate noise and provide extremely comfortable experience even after a long time wearing.

The biggest feature of the L series is that the BA's grade is great high. Like the 38D1X in the low frequen-cy band and the 23 series in the high frequency band, they are generally used in over $2000 HIFI products. Although the drivers are imported from Knowles and Sonion, they are of different series. driver prices vary widely. The cost of BA of the high-end HIFI product line is several times that of the socalled domestic custom-ized drivers and disassembled drivers, not the BA of the HIFI product line. When you choose a earphones, if it is not a branded eraphones, then the material is the most intuitive to see whether the it is conscience. The L series is a series with solid materials.
