Tey is tame as he has a respiratory problem and was treated for it in the shop before I bought him, so I am able to handle him a lot. He doesn't seem nervous, he's definitely less skitty than Ella and her ears are always up. He doesn't freeze if I make the noise (Ella does freeze at certain noises), but he just continues as if nothing has happened. I will keep an eye on him but he doesn't seem unwell currently. Also, thanks for the vet, I'll have a look.
