I just purchased a pair of soundcore Liberty air wireless earbuds. They sound great they're very comfortable the only problem I'm having is when I make a phone call nobody can hear anything I'm saying! It seems as if the microphone starts to work and then cuts out. And I cannot find any information anywhere to troubleshoot the issue. Please help! Am I overlooking something? It would be nice if there was a downloadable manual or troubleshooting guide online but I just can't seem to find anything anywhere. Any help would be greatly appreciated.
