Difference in Xbox One controllers S and X?

Maybe stupid question, but I explain;

I want to give my controller a new design, but I've read in the comments that the buyer has an X controller, but the buttons for a S controller. This baffles me now, because I think that the controllers (of design and build) are all the same.

Can someone possibly enlighten me there? (I have the controller of the X).

The S has, as far as I remember, no vibration motor.

That's not true. Of course, he also has a vibration motor.

Since I own both a One and a One X and also many controllers, I can assure you that there are no differences.

In the trade, there's only one type One controller to buy and none for One, One S or even One S.

What is there are normal controllers in umpteen special designs or alternatively the Elite Controller in two variants.

If you would like a self-designed controller, I recommend the following link. https://xboxdesignlab.xbox.com/de-de/

Thus, depending on your desire, a lot of money but the result is absolutely convincing. Qualitatively an original one controller with individual design.

I do not want to spend extra money on something I already have, just change the buttons. That's enough.
