Hello,
So I connected my headphone today with an aux cable to my pc but I noticed that the headphone is fading songs and making an electronic voice, So I tried to connect it to my phone via Bluetooth but it worked normally, So I decided to take a look inside the headphone to see if any wire is out of its place but I found that all wires connected to its place, I tried to reconnect my headphone to my phone via an aux cable but the same thing is happening, I don't know if the port in the headphone is broken or the aux cable how do I differentiate?
