E-Stim Step Sound M

Balanced Stepped Urethral Sound with Four Widths

The E-Stim Systems Step Sound M Stainless Steel offers a versatile middle ground within the stepped sound range. Its 20 mm stages, 80 mm insertable length and four progressive diameters create a measured journey from 6 mm to 12 mm. The Step Sound M gives each width more length than the compact S model without moving into the deeper reach of the larger options. That balance makes it appealing to experienced users seeking a substantial electro-compatible urethral sound that remains manageable and controlled.

Progressive 6 mm to 12 mm Design in One Solid Sound

Rather than choosing one fixed diameter, the Step Sound M incorporates 6 mm, 8 mm, 10 mm and 12 mm sections in a single mirror-polished form. The sound begins narrow and increases in defined stages as insertion depth grows. Each step is 20 mm long, allowing you to spend more time at each width before reaching the next transition. You can stop at the stage that suits the session or gradually become familiar with the wider sections over time.

Compatible with E-Stim Systems Power Equipment

The Step Sound M Stainless Steel is machined from solid stainless steel by E-Stim Systems in Watford, United Kingdom. Every piece is hand polished to produce the smooth mirror finish expected from the UltraSounds™ collection. A standard 4 mm banana socket is machined into the base for connection to the 2B, ElectroHelix, ElectroPebble, ABox or E-Stim Remote. The sound requires a second contact point to complete the circuit.
