Bolted Deluxe Silicone Urethral Sound Set by XR Brands

Bolted Deluxe Silicone Urethral Sound Set by XR Brands is a three-piece urethral sound set crafted from medical-grade silicone with graduated diameters of 7.5mm, 10mm, and 11.5mm. Each sound measures 13.75 inches long with a precision-tapered tip for smooth insertion. It suits experienced practitioners who want professional-grade equipment and complete control during urethral exploration.

What you're getting

Bolted Deluxe Silicone Urethral Sound Set by XR Brands gives you three graduated sounds in one complete set. Each is moulded from medical-grade silicone—a non-porous, body-safe material that resists bacterial growth and sterilises easily. The tapered tips guide smoothly into the urethra, while the flexible shaft adapts to your natural anatomy. Unlike rigid penis plugs, these sounds are engineered specifically for urethral insertion with precision-engineered diameters and extended length for secure handling.

The three-piece progressive system lets you build intensity at your own pace rather than jumping to one fixed size. Medical-grade silicone feels warm against the body and offers a unique blend of flex and firmness that rigid materials cannot replicate. The extended 13.75-inch length keeps you in complete command throughout each session.

The features that matter

• Progressive sizing system: Start with 7.5mm and advance through 10mm and 11.5mm diameters as comfort builds over multiple sessions
• Precision-tapered tips: Each sound narrows smoothly from tip to shaft, engineered for controlled insertion and minimal discomfort
• Medical-grade silicone construction: Non-porous material that is body-safe, bacteria-resistant, and sterilisable with boiling or toy cleaner
• Extended 13.75-inch length: Provides secure grip and complete depth control for confident, hands-on exploration
• Flexible yet firm: The silicone warms to body temperature while maintaining enough rigidity for controlled insertion and withdrawal

• Colour: Black
• Weight: Lightweight per sound, under 30 grams each (full set approximately 85 grams)

• Cleaning: Wash with warm soapy water or toy cleaner; can be boiled for sterilisation

Using a silicone penis plug without rushing

Start by washing the sound thoroughly with warm water and toy cleaner. Apply generous water-based lubricant to the tapered tip and your urethra—do not skip this step. Begin with the smallest 7.5mm diameter sound. Relax your body completely; any tension makes insertion harder. Hold the sound firmly near the shaft and guide the tapered tip slowly into the urethra opening. Pause if you feel resistance; breathe deeply and apply more lubricant rather than forcing it. Once fully inserted, you control the sensations through gentle movement or stillness.

Never rush progression to larger sizes. Most practitioners spend several sessions with each diameter before moving up. The 10mm and 11.5mm sounds should only be attempted once the smaller size feels comfortable and natural. Remove the sound slowly and gently, using additional lubricant if needed. After use, wash immediately in warm water and pat dry. Store silicone penis plugs in a clean, dry place away from direct sunlight. If you experience pain (not just sensation), stop immediately and allow recovery time before the next session.

Care and storage

Wash each sound thoroughly with warm soapy water or toy cleaner immediately after use. Pat dry with a lint-free cloth and allow to air-dry completely before storage. For deep sterilisation, boil the sounds in water for five minutes, then cool and dry. Store in a clean, dry place away from direct sunlight, heat, and silicone-based lubricants, which can degrade the material. Keep away from sharp objects. Inspect regularly for any signs of tearing or damage before use.

What to expect

The first time you use a urethral sound, the sensation is unlike anything else—a deep, intense awareness of the passage itself rather than external sensation. The tapered tip makes entry smoother than many expect, but never skip lubricant or rush the process. Most first-timers find the 7.5mm diameter feels manageable after five to ten minutes of patience and breathing.

The medical-grade silicone warms quickly to body temperature, which many people find more comfortable than the initial coolness of steel or glass. The flexible construction means it follows your natural curves rather than forcing a rigid path. Progressing to the 10mm usually feels noticeably different—fuller and more intense—but most practitioners find it approachable after two to four sessions with the smaller size.

Cleaning and maintenance are straightforward: hot water and soap, or boiling for full sterilisation. The silicone does not absorb odour or bacteria if dried and stored properly. Many practitioners keep their sounds in a clean pouch or container to prevent dust accumulation. The set lasts years with proper care, and the flexibility of silicone means there is minimal risk of cracking or splintering like rigid materials.

Common mistakes include progressing too quickly between sizes, using silicone-based lubricant (which degrades the material), and inserting without adequate lubrication. People who struggle often find success by slowing down and spending more sessions at each stage rather than treating it as a race.
