This UltraSound™ Smooth is a massive 12mm in diameter made from mirror polished solid stainless steel it is ultra smooth and ultra shiny with a sleek tapered end with a rounded tip. This design will give a gentle lead in to help stretch the urethra and help you take the full thickness more easily. With the 2mm differential between the tip and the shaft you get a gradual stretch as you gently insert this sound helping to open you up, ensuring that you can go on to take the full diameter.

All of our UltraSounds™ are designed with a stylish grooved base area to help with gripping them with lube covered fingers and are fitted with an industry standard 4mm socket. As this is monopole electrode so a second point of contact will be needed such as one of our conductive rubber loops or for prostate stimulation you can use the head of one of our Premium Electrodes.

This 12mm UltraSound™ Smooth for many is an eye watering size but for those experienced players it is just what they are looking for.


Depending on what you use will depend on the cable required, either a standard 4mm Cable or our BiCable for use with our 2mm Conductive Rubber Loops or Sticky Pads. Remember as this is a monopole electrode you will need a second point of contact to complete the circuit!


Cleaning is simple and easy, just wash them off in warm water and a light detergent or sterilising fluid or as they are solid stainless steel and unlike other cheaper sounds, they are safe to boil. Make sure the UltraSound™ is fully dry before storage. If you have any issues with your UltraSound™, just contact us as they covered by our Lifetime Guarantee.


Because of the nature of Sounding cleanliness is paramount so we suggest the use of Alcohol wipes to clean the sound immediately prior to use and the use of sterile lubricant. Both of which are available from us.
