I have an early pair of 600 ohm Beyerdynamic DT-990 Pro's.
I've had to replace the velvet ear pads once.....other than that.....they are still fine.
Despite their size.....they are soooo comfortable!
Great bass.....without being boomy!
Just a plain good all-around performer IMO.

For the price it's got to be good, those cans you have are not very expensive.
