I just figured it out. I was playing my guitar amp through them and when I unplugged the aux the wireless stopped working. It would connect but no sound except for this computer/glitchy sound. So I plugged the aux back in and out a few times. The last time I pulled the aux out really fast and they started working again. I think if you use any aux chord besides the factory one they don't fit as good and possibly bend the inside connection and the headphones think they still have an aux chord in them. Idk mine work now
