Remote-controlled and app-controlled C-rings are a modern category of c-rings that offer a new level of interactive pleasure. These devices, often made from body-safe silicone, typically feature a vibrating element. The key differentiator is that the vibration and intensity can be controlled remotely, either by a partner using a small handheld remote or via a smartphone app. This allows for dynamic, hands-free play and the possibility of long-distance or public control, adding an element of surprise and excitement to solo or shared sexual experiences.
