Ultra Sound Black – Premium Silicone Urethral Sound

The Ultra Sound Black is a high-quality urethral sound made from 100% medical-grade silicone, designed for safe and comfortable internal stimulation. Engineered for flexibility and precision, it provides the smooth surface and sterilisation benefits of a traditional metal sound, without the rigidity or cold sensation.

This device offers a unique combination of internal and external stimulation. Its curved handle sits comfortably against the glans, gently stimulating the frenulum while the smooth shaft and subtle ridges provide controlled internal sensation. Ideal for experienced users or those exploring urethral play safely for the first time.

How It Works

Urethral sounding involves gentle insertion of a smooth, lubricated device into the urethra to stimulate internal nerve endings.
The Ultra Sound Black features:

• Three cylindrical ridges for progressive stimulation.
• A curved handle that rests on the glans for mild external pressure and stability.
• A design that distributes sensation evenly while maintaining flexibility.

According to sexual health research, safe urethral play can heighten arousal, increase sensitivity, and enhance sexual awareness when practised hygienically and responsibly.
