Hi! Thanks for reading and for the reply!
I’m so sorry you had this problem. I actually wrote something about this about a month ago over here: https://medium.com/@Xander51/buyer-beware-it-looks-like-the-sony-mdr-1000x-has-a-build-materials-issue-c37d8ca3aa1f
Your comment reminds me that I should probably link that in this article as well, as I only added a link to my original 1000X review.
I really hope you’re able to get a refund before the return period expires. I’ve heard from other people with similarly crappy experiences. :( Hopefully Sony will change their headband plastic material soon. Reminds me of the issues they had with early DualShock 4 rubber.
