i have just received my second pair of AirPods and they have same problem as the first. Ear detection does not work when they are horizontal. The first pair it was the left one with the problem, this set it is both. So the simplest scenario is: I'm lying down on my right side, I take left had pod out of case and insert in ear nothing happens. If I slowly sit up it will chime when I get to about 45 degrees. This has nothing to do with the shape of my ears, they are a snug fit. I can simulate the problem by covering the sensors by gripping in palm of my hand and tilting the AirPod by turning my wrist. Apple support have been no help they are escalating the problem and will call me back tomorrow. Anybody else with this problem?
