Do headphone drivers degrade over time?

I've had my Sony MDR-V6 for about 15 years. They are still in visibly good shape with some wear on the pleather earpads. I have used them mostly indoors. They sound pretty good, but not great, compared to my speakers. And it seems that I'm a bit less enchanted by them than I was several years ago. Would new MDR-V6 sound better than my aged set? I avidly follow the commentary on the performance of various headphones in this forum and others, but I've apparently somehow bypassed discussions that address this topic.

Well, everything deteriorates over time...the V6's are some of the most enduring/well built headphones, but even those will break down, eventually. And, generally, one set of V6's will sound different than another set of V6's.

You decide for yourself if you need another one.

Anything that is used for 15 years (!) will show the age to some degree. Perhaps the V6 itself have improved over the years too.

15 years? I think its time for some new heapdhones.
