Invisibility and the Ring!

[Maédhros]

I wonder about if the men who had the Rings, could control their invisibility.
From the Published Silmarillion: Of the Rings of Power and the Thrid Age

Those who used the Nine Rings became mighty in their day, kings, sorcerers, and warriors of old. They obtained glory and great wealth, yet it turned to their undoing. They had, as it seemed, unending life, yet life became unendurable to them. They could walk, if they would, unseen by all eyes in this world beneath the sun, and they could see things in worlds invisible to mortal men; but too often they beheld only the phantoms and delusions of Sauron.

Does that means that they while wearing the Ring could turn on-off the invisibility of the Ring or they could only turn invisible while wearing them.
