Advanced Silicone Urethral Sounding Kit - Extreme Advanced

Hidden Desire Extreme Advanced offers this duo of matte black silicone urethral sounds for experienced practitioners: one with large regular beads and one twisted with a stopper ball. Both are designed to go further than introductory sounds in terms of texture and sensation.

Two stimulation profiles in one kit

The beaded sound creates rhythmic stimulation with each inch of insertion—each bead passes the urethral sphincter one after the other. The twisted sound provides continuous, more uniform friction. The stopper ball at the base of both models prevents accidental insertion beyond the safe zone.

Soft silicone: advanced safety and comfort

Non-porous medical-grade silicone is the material of choice for sounding—it is easy to sterilize, does not react with water-based lubricants, and its flexibility reduces the risk of injury compared to metal for users who have already mastered the practice. Always use with sterile water-based urethral lube, under strict hygiene conditions.
