I have the inspire (but still do not own the attachments) but from what I do know I can guess as to how it works. The inspire has a removable silicone cap to the head, this is removed the attachments then take its place. The thing is that the heads attach on by a notch feature (like an internal pattern that inter-locks like a puzzle piece). The silicone head that it comes with isn't particularly stretchy and I imagine the attachments to be made similar, so unless the vibe you have in question has a matching notch system, I don't see it working out too well.
