I'm at 10 years with my Ultrasone Signature Pros and they look and function just like new. Of course they're not wireless and don't have a DAC built in so there's very little to go wrong, but despite being a person that upgrades my phone and laptop frequently - I don't see myself replacing them for another 10 years - they're pretty much perfect audio quality and comfort wise.
