Problems with my 450HDs

My headset has died on my in the last day or two. The last time I remember them working I had them paired to both my phone and laptop now they won't turn on properly... they make static and don't get past the connecting stage of the start-up. Is this a physical issue or is it software related? I have tried many times to reset the headset however have not managed to do so before the headset turns off. The headset is at 100% battery as well

Any pointers would help heaps, Cheers
