I was using the AKG earbuds that came with my S10 phone for my Xbox ONE controller, the earbuds were working fine and the mic was fully working until suddenly the microphone stopped working, I plugged the earbuds into my phone and tried calling and talking off that but the microphone still wouldn't work. I can hear any audio and phone sounds, music, videos, etc. But I cannot speak through the microphone on the earbuds.
Thanks for reaching out! I'll be happy to look into what options are available. Will you please send a private message with the model code and IMEI number of your phone? http://bit.ly/2XERsky
