Songs stop for no reason & settings in app change on their own

Just bought liberty 4 hc and having all sorts of issues.
First off music can be playing then just stop. The actual Bluetooth connection hasn’t dropped the music just stopped , on Qobuz and Amazon music so not app specific. Press play again and all fone plays for a bit then stops again.
Second issue within the app set it to noise cancellation , then it just reverts back to normal without me touching it, again mid song. No reason for it.
I’ve reset the headphones , still doing it , deleted the soundcore app and even changed phones and doing it on both phones. Even got a replacement pair of headphones from soundcore, still doing it on this second pair. Anyone else has this as these are going back and getting a refund at this rate?
