Answer
Headless Services provide stable DNS entries for each Pod.
Quick Answer
StatefulSet Pods need stable network identities — pod-0, pod-1, pod-2. A regular Service would load-balance across them randomly. A Headless Service (ClusterIP: None) creates DNS records for each Pod individually (pod-0.service.namespace.svc.cluster.local) so clients can address specific Pods directly, which databases and distributed systems require.
