Black / Metallic objects seen flying NE to SW over Manhattan

I live in the Harlem area of Manhattan. My apartment has a roof deck from where I observed two unknown objects. While exercising there, I spotted the first dark circle moving with a steady velocity from the northeast to southeast. At first, I thought it was a balloon but quickly ruled this out as the object was perfectly spherical and moving too quickly in a straight line. It was too high to be a drone. At one point while directly overhead, it reflected sunlight and I could make out a metallic surface. My location is near La Guardia airport, but this craft was not observing any common flightpath. The object eventually faded from view as it proceed southwest. I observed a second craft approximately 15 minutes later, also dark and spherical, flying a similar path but more westward. The velocity and elevation appeared similar to the first craft. Neither craft displayed erratic movements. There were no lights / signals. In, fact, what was most strange was the ut! ter lack of any surface markings / characteristics.
