Why is my headphones blutoothed and connected, but my phone playing?
Turned on my Beats Solo 3 headphones, paired them, heard the jingle in the headphones signaling they were synced. Only sounds I get are the pairing and if I take the plug out (the little Apple adapter for Iphone8) And yet, music comes though my phone. I tried resetting headphones and disconnecting from Bluetooth but same result.
