I like the idea of the removable cable, so I can replace it in the future in case it fails. This is the number 1 reason to throw away a set of headphones, as they are very difficult to repair, so this is a big plus.
The foams, as you would expect with any headset, will deteriorate over time, but there are kits available to replace them. In other words, I expect my headphones to last me many years.
