“There has to be something else” might be the thesis as Panasonic thought about using a material for earbuds which normaly is used to imitate Diamonds. The speak is about Zirconia often seen in a pair with Moissanits but this time used to dramatically reduce sound distortion. These pair of sound smoothing buds does also come with removable cables for an optimized organization and replacement. Be prepared for the high karat variation.
