Silicone Urethral Sound — Depth Charge by 665 Leather

Silicone Urethral Sound User Guide & Play Styles

Getting Started: What Advanced Users Know Before Their First Sounding Session

The body-safe silicone on this advanced urethral sound means you’re working with a material that can be fully sterilized — a non-negotiable for urethral play. Before insertion, wash hands thoroughly and sterilize the sound. Always use a sterile, water-based lubricant; generous application is not optional. The tapered tip of this textured urethral sound allows you to work at your own pace, letting natural relaxation guide depth rather than pressure. Clean the sound and your hands before play — that’s the discipline that makes sounding rewarding. For more on material safety, see our guide to sex toy material types.

Solo Sessions with a Medical-Grade Urethral Sound

Sounding is an inherently solo-focused practice in most sessions, and this 665 Leather medical-grade urethral sound is well-suited to unhurried, private exploration. Insert slowly, pause at each of the 13 bumps, and let the sensation register before continuing. The real reward of this body-safe urethral sound comes on the deliberate, controlled withdrawal — each bump delivers a distinct wave of internal stimulation. The ridged handle ensures a firm grip even when things are lubed up. Explore our full range of advanced kink products at the medical devices category.
