Question about WH-1000XM4 - 318650

Hi! From what I've been able to find online, it seems that the oads are made out of soft protein leather. There's also a foam inside but I wasn't able to find its name. From what I can see on mine, the pads definitely feel like leather. That being said I cannot guarantee 100% that this product is silicon-free. Nothing is detailed on the product's box.

Hi, unfortunately I don't have the answer to your question.
