Razer Opus Not turning on

Hi, The headset was working fine two days ago, but it suddenly stopped today. I tried turning it on, charging it, and i have pressed the power button several times but its not working but nothing worked. When pressing the power button, the power light (?) never turns on. It was fully charged before I tried using it, but now it refuses to charge no matter how long or what cable is used. The light never turns on. This is the first time that this has happened, and I’ve only had the headphones for 8 months. The only issue is that it have some cracks on the sides . Is there anything I can do to fix it?
