Product Launch: HarmonicDyne P.D1 Planar Dynamic IEM


HarmonicDyne is a newer manufacturer who made some noise with their gorgeous Zeus and Helios headphones. The company has become renowned for their powerful sound tuning and gorgeous selection of materials. The P.D1 is their first IEM design that continues this legacy.

5-axis CNC milled metal housings may draw the eye yet it’s what’s inside these IEMs that’s most intriguing. This is a hybrid DD + planar earphone, similar to what oBravo are doing. Inside is a 10mm high-efficiency dynamic driver sporting a CNT surround and DLC dome, an interesting combination. This is paired with a 10mm customized planar magnetic driver. The overall sound profile promises to be smooth and natural.

The P.D1 retails for $379 USD with first units shipping out in mid-June. You can read more about it and treat yourself to a unit on HiFiGO!
