The band on my Surface Headphones 2 Broken

I have my Surface headphones 2 since may 2020, their warranty just expired. I use them carefully and normally, they have never been dropped on floor. Last week, when I wanted to take them off, the band on the headphones broke. This was very surprising to me because they were in very good condition and I did not even open them wide enough to fit on my head. There was no sort of excessive force used when going to put them on, they just seemed to snap out of nowhere. After doing some research, several people have had similar problems and it seems to be a design defect with the headphones. Again, I have always taken very good care of them. I would expect them to last a lot longer than they did. They still power on and work fine, but how can I use them if the band is broken? Is there any way my headphones can be replaced or at least have the band on them replaced? Even if the warranty expired, I wish the replacement could be free because of the design defect.
