How We Have Developed P.D.1HarmonicDyne quickly took a place in HiFi headphone industry with its professional high-standard headphones, like Zeus and Helios. Both headphones have received many positive feedbacks and advice which greatly encouraged the team to go further. Thus HarmonicDyne is stepping into the IEM industry with their latest pair, the HarmonicDyne P.D.1 which features a hybrid driver of planar and dynamic driver with aluminum alloy shell. Derived from the two letters from planar and dynamic driver, P.D.1 comes into being. The name speaks for itself as a hybrid driver IEM and its unique driver configuration will deliver you a natural sound.
10mm Planar Driver+10mm Dynamic DriverHarmonicDyne has equipped the P.D.1 with the latest planar driver with high magnetic flux paired to a customized dynamic driver unit (CNT at the edges and DLC Dome), bringing the best of both worlds together to create a unique musical experience. These two drivers greatly complement each other to present you a uncomparable sound.
