Top Secret Technology

IE's greatest difference from other audiophile speakers lies in the founder's years of R&D on the core technology – "Sound Dyeing.”

While achieving high fidelity, the multi-level sound presentation makes the sound more delicate and emotional, this is suitable for all kinds of music to stir in the carriage.

IE sets an unreplicable standard in technology, creating a nearly perfect audio system. This prevents other manufacturers from imitating and producing subpar products with IE shadow technologies.

The unique technological innovations of IE are highly confidential, and robust security measures make IE a truly one-of-a-kind presence among Hi-End brands.

IE's obsession with craftsmanship is beyond imagination.

The production cycle of the president series speakers is 150 days, with each speaker undergoing 93 complex processes. From the smoothness of unit surface treatment for smooth airflow, to the uniformity of multi-layer glue fine coating to reduce distortion, and the pursuit of zero-error unit assembly for optimal sound matching.

IE embodies the sp irit of craftsmanship to the fullest.

The ability to quickly respond to external airflow instability ensures robust low-frequency output at every moment.

The non-reproducible signboard adopts the low-frequency vortex storage technology that propels high power to even greater strength.
