I have a new pair of Anker Soundbuds Curve. They connect flawlessly to my iPhone X and the first few times the phone audio worked. Now 7/10 times I am unable to hear any audio from my phone even though the device is paired. I can still control volume (volume bar goes up and down), pause/play, but no audio. I’ve updated my iPhone, and I’ve disconnected the Bluetooth and repaired multiple times.
