About US


In 2018, the journey began with a dedicated acoustic team that focused on developing cutting-edge acoustic technology. High-quality 3D printing and acoustic testing equipment were acquired and a unique acoustic lab was built.

With our relentless pursuit of excellence, in 2019, a breakthrough was achieved with the first engineering prototypes that featured a novel circuit topology and acoustic structure. This enabled a single BA driver to deliver stunning HiFi performance.

Continuing our technological upgrades, in 2020, the technology was refined and the second generation of circuit topology and acoustic structure was developed. Three technology patents were secured for the innovations.

In 2021, the technology was commercialized and new applications were explored. The original S&E Math technology was recognized by the Chinese Academy of Sciences and selected for the “China-Denmark Technology Exchange Roadshow” to showcase the technological prowess of Denmark.

By 2022, the Performer series earphones were successfully launched worldwide, receiving rave reviews from customers and critics alike. The S&E-Math technology also won government funding from the Suzhou Municipal Government’s “Leading Talent Award”.

As of 2023, the latest masterpiece is ready to be unveiled: the 1DD+7BA Performer 8. Single Balanced armature driver IEMs based on S&E-math technology are also in the pipeline.

Stay tuned for more details.
