Here are few problems I’ve encountered so far:
1. Every once in a while (few days) I take them out of case and one did not charge at all, while other did.
2. For some reason I have to turn off Bluetooth on my iPhone, so I can connect my MBPro to my APP, otherwise they automatically switch back to my iPhone within 10 seconds...
Overall I can live with these problems and I bought AC+ for them, so honestly waiting for end of summer when I go back to California and stop by Apple store to maybe receive a new pair
