Decent condition, comes with clear visor and mic (untested). Unable to identify the model number, as there's no label that I can find inside.
There's a label on the back that says SP-H6 but I'm unable to verify that model exists anywhere. Looks to me very similar to an HGU-55/P.
Some scratches on the clear visor. See pictures for more details on condition, and feel free to message any questions/comments!
