Why won’t it turn on... like at all?

So my headphones aren’t actually beats but they didn’t seem to have my headphones on there so I’m just gonna do this instead… I’ve had these headphones for about three days and they all of a sudden stopped working (they’re IJoy Bluetooth over the ear ones btw). Like the light on the side won’t turn on at all unless it’s charging- and even then I can’t pair it or listen to anything (holy f*ck in the middle of writing this it just made a noise that scared the !&&* outta me) and it’s super annoying bc they haven’t been dropped or anything. And yes, they are definitely not dead, had them charging overnight before writing this.
