Sounds come in a range of sizes, and that's is a problem.
Our standard UltraSounds run 6mm, 8mm, 10mm and 12mm. Four diameters, and no honest way for someone new to sounding to know which one they want before they've bought one. You have to guess. Most people do, and a fair few guess wrong, ending up with something too thin to feel much or too thick to make a comfortable start.
So we thought we'd fix it in the workshop. One piece of stainless, all four diameters on the same shaft, thinnest at the tip and stepping up as it goes. Slide it in, notice where you stop, buy that size. That's a gauge, not a toy, and a sizing gauge was all we thought we'd built.
A confession
Now, a confession. I don't do sounding. Twenty two years of making this kit and the one thing that still puts the willies up me willy, is a length of steel going anywhere near my willy. Which is exactly why we have a test team, and why the gauge went out to someone who does.
The report came back and it wasn't what we were expecting. No notes on the diameters, nothing on whether the measuring actually worked. Just a question.
"Why are you wasting this as a sizing tool?"
We sat with that for a bit. They were right. We'd spent the design effort making something that climbs through four thicknesses in a single insertion, then filed it under measuring equipment, which is a bit like machining a lovely thing and using it as a doorstop. The stepping was the interesting part all along. We'd just been treating it as a byproduct.
So we put a socket in the base.
A 4mm banana socket, machined into the end of what had been an inert length of stainless, and the gauge became an electrode. Current goes in and all four diameters start doing something. As far as we know nobody had built a stepped sound that does that, which makes these the first electrified stepped sounds anyone has made. We got there by accident, via a ruler.
Once it was a product rather than a measuring stick, one size stopped being enough. A gauge only ever needs to exist in one form. An electrode that people are going to play with needs to suit the person playing with it, so we extended the set.
What ended up on the shelf
Every Step Sound climbs the same four diameters. What changes between the four models is how long each step is, which sets both how deep the sound reaches and how much distance sits between one thickness and the next.
| Model | Step length | Insertable | Total |
|---|---|---|---|
| Short | 15mm | 60mm | 80mm |
| Medium | 20mm | 80mm | 100mm |
| Long | 25mm | 100mm | 120mm |
| Extra Long | 30mm | 120mm | 140mm |
Short gives the quickest progression and keeps things near the head. Extra Long spreads that same climb over twice the distance and takes you furthest. All four come off the same stainless as the rest of the range, machined and hand polished in the same Watford workshops.
We didn't plan the next bit either, and there's no sense pretending otherwise. The original idea hasn't gone anywhere. Your fit is still built into the sound, so you don't have to commit to a diameter on day one. Stop where it feels right this week, go further another time, and you don't need to buy anything else to do it.
Connecting one up
That socket is the same 4mm fitting as the rest of the UltraSound family, so it works with every box we make. The 2B, ElectroHelix, ElectroPebble, ABox and the E-Stim Remote.
It's a single connection, so it needs a second point of contact to complete the circuit. Pair it with a sticky pad, a loop or an ElectroRing.
Before you get carried away
Urethral play asks more of you on cleanliness than anything else we make. Clean the sound with an alcohol wipe immediately before use, and use a sterile lubricant throughout. Not the gel you use for everything else. Sterile.
Made in the UK in our own workshops, and covered by our lifetime guarantee like every e-stim powerbox and insertable we build. The new Step Sounds come in four lengths, £42 to £48.
