Alternative approach

... Because my goal IS for hubs to feel something, not go into the Void.

I like the idea of the void and not feeling anything. I got a sung and tight cobra, I was thinking of larger size but was advised to go a size smaller than I thought, it was good advice. The sung is quite comfortable and the bit of movement gives me pleasurable sensations that I can do nothing about which is lots of fun. The tight is a perfect size, I really feel nothing as everything fits so well. I'm want to have my chastity journey to be about having no self induced orgasms, I'm only allowed to orgasm with someone. My only issue is my foreskin, depending on how things sit the tip can extent out and sometimes gets pinched in the tight. I already feel a need to address this somehow and maybe a different make / model.

Because my goal IS for hubs to feel something, not go into the Void.

The void is by all accounts very real. Can't feel anything etc.

But that's only in between when he's aroused. And he will get aroused and feel the Cobra becoming tight and restraining. He will definitely feel that.
Sometimes he will get an attempt at an erection (prevented of course) for no known reason.
Other times something will turn him on, something visual, sensual, or maybe just his own imagination.
Other times you can make sure he gets aroused by teasing him.
He will feel all of those things.

It's just the in-between times when the Cobra doesn't actually cause the arousal in the first place.

But maybe you want more deliberate sensation from the cage.
My man wears a House of Denial cage (when he's not nubbed) that does just that.

Questions welcome if you want to know more

Dont worry. It is a perfect first cage. I wear one occasionally.. with permission that is.

The void we talk about is primarily because it lacks weight and it fits so well.

To begin with, believe me he will feel lots of things. Frustration of course whitch is something that he has to get used to, attempted nocturnal and daytime erections, leaking and a constant state of horny.

The Cobra is the perfect cage to get your man exactly where you want him. Locked, horny, frustrated and doting on you.

Just wait for those little puppy eyes wanting a little tickle and you'll never look back.

The void doesn't kick in until everything settles down by which time you will most likely have enyoyed this so much you'll have ordered another cage or three.

I have to say of the many, many cages we’ve experimented with the nub is the one of choice by her and I must agree it sets well with me too. The void spoken of is as said before the feeling of not feeling when nothing is happening down there. If anything the void will cause him to do a lot of self evaluation and think of his kh more often. At which time snugness starts up again.

There!
I knew a wearer (or 2) would be able to write a better answer than mine as a keyholder.

As @Mr Pickle says, "The void doesn't kick in until everything settles down” - I'd forgotten about that.

And @Tongue+groove says the void will make the wearer think about his keyholder and “the snugness starts up again”

I agree.
Arousal happens a lot (The snugness starts up) and Herbi reports feeling it a lot.
It's just the comfort and excellent fit of the Cobra mean that the cage itself doesn't actually cause arousal (I think!)

I might also add that the nub helps the wearer to appreciate a good ball massage.
