Compatible with: Sennheiser HD 620S

After recognizing the HD620S's unique potential, Zach embarked on an intensive development process involving numerous prototype iterations. The breakthrough came with the angled form factor—a departure from traditional flat pad design that specifically addresses the HD620S's closed-back architecture. This innovation optimizes driver positioning to unlock performance characteristics that simply aren't achievable with conventional pad designs.

Engineered exclusively for the Sennheiser HD620S after extensive development, these pads feature a unique angled form factor that sets them apart from ZMF's other 5xx series offerings. Zach's innovative angular design optimizes the HD620S's driver positioning, unlocking enhanced depth, layering, and punch while expanding the soundstage significantly.

Through multiple iterations, this precise angled construction addresses the HD620S's mid-bass characteristics, creating a more cohesive and wide sound signature. The result transforms the closed-back HD620S into a more spacious, dynamic listening experience while maintaining its inherent benefits.

Compatibility Note: These pads are specifically engineered for the Sennheiser HD620S. While they share the 5xx series mounting system, the unique angled design is optimized exclusively for HD620S acoustics and may not provide optimal performance on other 5xx models.
