“Ortho” is a microplanar magnetic driver developed by MADOO. There are two types of planar drivers: "push-pull drive" and "single drive", and "Ortho" uses the push-pull drive method. Due to the high degree of difficulty in incorporating it, it is difficult to make it small and lightweight enough to fit into earphones, but with the help of skilled engineers, we have succeeded in developing a high-quality push-pull type planar driver that is the size of an earphone.

The tuning applied to Typ622 further brings out the potential of "Ortho", which is good at a wide range of expression, from powerful mid-low range to glittering and delicate high range.
