Does anyone have problems with the Starfield headset?

My headset keeps disconnecting because it has no battery, even though I'll leave it charging all night. I'll then do the thing where you hold down the mic and power button and insert the USB cable to reset it and then it will say it has full battery and will last for about an hour until it disconnects again.

I've had a look at returning it to Microsoft but it says that if it's faulty they'll replace it for a refurbished one! What's that all about. They should be replacing it with a brand new one surely?
