There is a guide for 3D printing and replacing cracked headband on this headset here: Sony Gold Wireless Headset Headband by Ren If you do not own a 3D printer, you can use the site (World tab) to find someone nearby to print it for you. I am not transferring the whole guide here because it’s mostly about 3D printing but still feel it would be a pity to omit it completely, thus this post.
This is the post. It’s more of knowledge sharing than a question.
