Sonos one as surrounds - height?

[welldog]

Just purchased a couple of Sonos One speakers to use as surrounds added to my Beam gen 2 soundbar.
These will be wall mounted with the sofa up against the same wall.
What height should I place these speakers on the wall?

Just above head height is normal
