Not sure what caused this issue, but suddenly my right earphone on my Audio Technica M50xBT has been much quieter than normal (I use them with the wire when gaming on my PC). I tested them wirelessly and on my phone and they worked fine. Both earphones have the same balance, but the right earphone is much quieter (but not silent) than the left one. Also, while checking my audio devices, there's one that has appeared called Headset Earphone and under it says 'Wireless Controller'. My audio drivers are up to date and the problem still stands after restarting my PC. Thanks.
