ZMF HD620S Sub Pads

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.
