The 3 rd PU doesn ' t do anything as well . All the same . I ' m aware of changing only one thing at a time , that ' s how I proceeded with all the cables , PU and headset of the 2 nd unit to make sure I know what fixed it for me . Well , if it would have fixed anything . I don ' t have any room with dark walls , though I ' ve tried different directions in my living room and my small office . Though the setup options are limited considering the length of the camera cable . They sent you the wrong cable ? Wow , gives me hope about calling customer service for having them figure out what my issue is after anything I ' ve done so far . <| sep |> He sounds like a bellend <| sep |> Owen Shroyer the destroyer ! Man I love this guy owning libtards hahaha
