Life P3 cuts out

I’ve been lucky enough to receive some Life P3 earphones. As they’re a gift, I don’t have a receipt.

They sound amazing but they cut out when I put my phone in my pocket or move it 40-50cms away from the earphones?

Using a fully up to date Samsung S21 5G.

Does anyone have any work arounds?
