The ElectraStim Silicone Noir Flexible Urethral Sound is a precision-engineered electro-stimulation accessory designed for comfortable, controlled urethral play. Crafted from platinum-cured, medical-grade conductive silicone, this sound delivers focused electrical stimulation deep within the urethra, producing intense and highly targeted sensations that are simply not achievable through external stimulation alone. The silicone compound is phthalate-free, body-safe, and fully compatible with the unique demands of electro-stimulation play.
One of the standout qualities of this sound is its flexible construction. Unlike rigid metal sounds, the soft, pliable silicone gently conforms to the natural curvature and anatomy of the individual user, making insertion more comfortable and the overall experience more accessible — particularly for those who are newer to urethral stimulation. With approximately 150 mm (5.9 inches) of insertable length, it provides a generous range of depth options, while clearly marked measurement notches at every inch allow the user to monitor insertion depth at a glance. This depth awareness is especially important during electro play: the smaller the surface area exposed, the more concentrated and intense the electrical sensation becomes, so many experienced users prefer full insertion to distribute stimulation more evenly.
A key technical advantage of this sound is its bi-polar design. Traditional urethral sounds are unipolar, meaning a second electrode must be placed elsewhere on the body to complete the electrical circuit. This sound contains both poles within a single accessory, allowing it to function as a fully self-contained electro unit. This makes it an excellent choice for those who are new to electro-stimulation, as it removes the complexity of managing a second electrode and allows the user to focus entirely on the sensations being experienced. For those who prefer conventional play without electrical stimulation, the sound can also be used independently, without connection to a stimulator.
The 7 mm diameter of this model makes it a comfortable step up for users who have some prior experience with urethral sounding and are looking for a slightly fuller sensation. A 5 mm variant is also available for those who prefer a smaller introductory size. Both versions connect easily to the full range of ElectraStim stimulators via the standard 2 mm connection, giving users full control over the intensity, frequency, and pattern of electrical output.
Whether used as part of a solo session or incorporated into partnered play, this sound offers a sophisticated and body-safe route to a unique form of internal stimulation. Its flexibility, clinical-grade materials, and self-contained bi-polar circuitry make it one of the most user-friendly electro urethral accessories currently available.
Key Features:
Care & Hygiene: As a medical-grade silicone accessory used for internal urethral insertion, thorough cleaning and sterilisation before and after every use is essential. The non-porous silicone surface resists bacterial build-up and can be sterilised by boiling, wiping with a 10% bleach solution, or using a dedicated toy steriliser. Always use a sterile, water-based lubricant specifically formulated for urethral use during insertion, and never use silicone-based lubricants with silicone toys.
