I sold this guy a pair of XM4’s a few days ago. They were brand new but just taken out of the box. They arrived to his address yesterday, but this morning I woke up to him requesting a return. He claims that I didn’t send him the Sony XM4’s but instead he said I sent him some random pair of Bose headphones. Where do I go from here. I actually sent him the Sony headphones. I’m worried that when he returns my items, it won’t actually be my headphones, but this random pair the he has. What do I do?

EDIT: He just messaged me back and said that he mixed up the box with another one, and he did receive my headphones that I sent. Thank you guys for the help though👍
