A coherent interface between a mechanical oscillator and superconducting electrical circuits would enable the control of quantum states of mechanical motion, but such interfaces often result in excess mechanical energy loss. A new material-agnostic approach is shown to achieve strong electromechanical coupling while preserving a long phonon lifetime.
