Yup, same issue I have regarding finicky Bluetooth connections. Frequent dropouts while just turning my head to cross the road while phone is in my front right pocket. Gets worse when a light gust of wind blows my way. For each time the left bud 'pops' and loses connection for 1-2 secs, the music will then shift from center to the left. I needed to pause music, wait for 1-2 secs and resume to 'adjust' the sound back to center. These buds are strictly for indoor use only, coupled with your phone lying just next to you, and you best not make sudden movements or jerk away from your seat else you get another drop out.
But oy, the sound man....really makes it hard to return/refund them after sampling their sound for a few days. Just like being caught between a rock and a hard place.
