Sounding is one of the fastest-growing fetishes around, and the Sport Fucker Ultra Sound is a standout way to explore it. Made from medical grade silicone, it gives you all the benefits of an ultra-smooth, sterilisable surface without the rigid, unforgiving feel of traditional metal sounds. Flexible, body-warming, and seriously satisfying.
What sets this sound apart from a standard plug is its design. Three cylindrical ridges – slightly wider than the shaft – add a layered sensation as the sound moves. The curved handle arcs over the head and rests with its ball right on your frenulum glan, delivering a combination of internal depth and a subtle external pressure at the same time. It looks just as good as it feels, with the handle sitting proud and the shaft buried where it counts.
Design details that make the difference
The shaft tapers from 4.35mm up to 4.6mm, with ridges measuring 5.1mm-5.2mm and a tip of 5.2mm – a gradual progression that makes insertion smooth and controlled. The overall length is 12.7cm, with a ball diameter of 1cm and a distance from ball to shaft of 2.3cm. That curved handle isn’t just for show; it anchors the sound in place and keeps stimulation exactly where you want it. Available in black (as well as blue, grey, and red across the Sport Fucker range).
