Two orbs with no sound

I just arrived home. I went on my back patio, 2nd floor apartment and I noticed two orbs just appear right in front of me just above house tops in a southeast direction. They were circling each other so I ran to get my high speed camera but it was dead, do I grabbed my cell and started recording. By the time I hit record, they stopped circling and flew extremely close together. Keep in mind the the location they were above was right above my medical clinic i work at. All residential, air craft do not fly that low with lights that bright. There was absolutely no sound. I can always hear planes much farther and helicopter blades are very easy for me; ex Military Veteran. I posted the video on Facebook and a old friend I use to work with responded on FB that she witnessed the same two lights.
