I've raised a repair for these after I have had them since July and the material from the band had come away from the plastic, I believe this is a defect due to way it had come away was clean, no fraying it looks as though they glue it to the inside I'm not sure, I'm not the only one on this https://www.reddit.com/r/sony/comments/x1zoax/anyone_else_having_issues_with_sony_h7h9_quality/
has anyone in this community also had this issue?
