Only if they are not under warranty. Otherwise using warranty to is better. Because fiddling with them is a gumble

That sucks. I have been abusing my HD650 daily since 2017 and they are still going strong because they were made in Irelan and was thinking of buying the Ananda because of their sound quality but after seeing comments about their buil quality I changed my mind.

Did you check the resistance with a multimeter. It could be a bad soldering job and the driver is still good. I would give up on them immediately. I would open them and see if the wires are still attached to the driver
