For steamdeck on the couch something like the xreal or rokid would be better. Some people have been able to make VR work with steamdeck with bad performance but they only tried VR games so don’t know how it would be with regular games.
I bought a pair when they were still going by NReal name and they worked well with steam deck and my laptop. Battery life would last longer with only the glasses on. I didn’t like always having to wear contacts so picked up a pair of Rokid’s glasses too. Those have built in diopters and have been working well.
