Kids don't pick up such cues without prompting.
I know some that even in musical/dancing training have no rhythm at all.
It typically would be best to ask him to relay his best/favorite headphones to you. Depending on his likes\taste of sound stage amount of Bass.
He could probably recreate a similar near field setup using one of your bookshelves. Maybe fun? To see how different your tastes may be?
When I was a kid we all thought Boomboxes or an old 2 channel hooked up ghetto surround was the greatest thing.{multiple old speakers everywhere}
