Silicone Sounding Rods — Master Series Hardware Nail & Screw by XR Brands

Silicone Sounding Rods User Guide & Play Styles

Advanced solo sessions with textured sounding rods

These advanced urethral sounds are built for experienced users who know what they want and how to get there safely. The smooth hexagonal nail offers a clean, uniform glide, while the spiral-textured screw makes every centimeter feel deliberate. Use a generous amount of water-based lubricant — silicone lubricant is not compatible with this silicone material — and always allow your body to dictate the pace. Alternate between both body-safe sounding rods as your comfort and confidence grow. For a broader look at kink-category tools, explore the Medical Devices collection or the full Kink Pleasure range.

Shared exploration and couples play with black silicone sounds

Urethral play at this level can be an intensely connecting experience when approached together. The XR Brands Master Series duo gives couples two distinct tools — nail and screw — to introduce variety and rhythm into boundary-pushing sessions. Trust, communication, and patience are foundational here. The black silicone construction keeps both rods easy to clean before and after, so the focus stays on the experience itself.
