Broken WH-100MX4

These are almost 400 dollars and they broke easily. I’ve had them for about a year and a half and I really depend on these since I have medical issues Could a tech repair person fix it? Or could I?? I can’t afford another pair and no other headphones cancel noise like this. Can someone give me recommendations dations for cheap brands I can use that cancel sounds really well whether it’s earbuds or headphones
