Description
In 2014, OPPO Digital released the PM-1 and PM-2 open-type planar field drive headphones, which won the EISA Award, a European AV equipment award, and were highly acclaimed both in Japan and abroad.
On the other hand, many users in the Japanese market and elsewhere have expressed their desire for a sealed planar field drive headphone suitable for portable use. OPPO Digital has succeeded in developing an even smaller unit to bring planar-field-driven headphones, which had been limited to a few enthusiasts due to their high cost and low performance, to a practical level for many customers. OPPO Digital is opening up a new stage in the world of planar field drive headphones.
