Razer Hammerhead TWS (2nd Gen) doesn't work

Maybe you guys can help me someone? I have some issues with my RAZER HAMMERHEAD TRUE WIRELESS (2nd Gen). The problem was in fact, that my earbunds won't turned off while I'm putting them in the case so the next time I'm using it, they just always discharging and charging at 20% max. So I was start to trying figured it out myself and just tryed to turn them off completely by holding the button for 5 sec. and then tapping 3 times and holding for 3 sec. After that I heard a phrase like: "factory restart, power off" or something like that and, after this, I can't turn my earbuds on no matter I would do. Can you please try to help me?
