I own a Samsung Galaxy S8. Whenever I try to use my AKG earphones or any earphones with a mic, I can only hear the music but not the vocals of the song. I have also tried to use my AKG earphones with my friend's Samsung S7 and it did the exact same thing.
My earphones are fine when I use it with my laptop. And the only earphones that works with my phone are the ones without the mic.
