Sennheiser has been bought out by sonova, If you can try to get a couple older pairs and you’ll get a lifetime product. Hd560-600 range is amazing headphone, the old marble counter 600 has last me about 16 years and countint, no defects so far!

If you want something long term and easily repairable look into meze 99s, they are fully servicable with a long gurantee! Amazing sound on the 99s and if you want to go budget-er the 99 neo’s are good as well
