Quite cook ring and Prostate butt plug help

Hi well I am looking for Quite cork ring.

I did see this

Tracey Cox Supersex Twin Silicone Vibrating Love Ring for Couples

and as I live with other student in the same house I need something that is Quite so I would like to ask how sound does this make?

I am also looking for cook ring that used normal size battery like aaa. I dislike the LR44 battery so I would like to steer clear of them.

What would you advice?

I also need advice on this
