This technology focuses on minimizing the low-frequency magnetic fields produced during the process of converting electrical signals into acoustic signals in the headphones. The VIRTUOSO uses an upgraded material based on “MU Metal”; a special military metal used in the original ULE technology. This new material allows for reduced shieling thickness while increasing the overall size, and is installed between the source of the electromagnetic radiation and the human body, resulting in enhanced protective capabilities over previous technology. This setup bends the direction of the electromagnetic waves before they reach the body, reducing emissions by approximately 98%.
