OPPO PM-1 EU

The OPPO PM-1 headphones offer a new way of thinking about orthoplanar transducer technology.

The PM-1 is characterized by a natural, dynamic and clear sound quality with an emphasis on comfort and reduced weight. It is the result of many years of research by a team of passionate audio and acoustics engineers, materials science specialists, and audiophiles.

A number of technological advances were made in the design of the PM-1, including the use of a unique 7-layer diaphragm, double-sided spiral coils, and an FEM-optimized magnet system.

All of these aspects of the OPPO PM-1’s design combine to deliver a transparent, highly dynamic sound that has well-balanced tonal qualities with very low distortion, providing a listening experience that is both relaxing and capable of reproducing all the nuances of your favorite music.
