First ever review on these and I have owned them for over 9 years.  Still going strong, but there have been several issues over the years.  The first issue had to do with the earpads.... they only lasted about three years and had to be replaced.  Not an expensive replacement, but worth noting.  Then, sometime within the last 5 years, I started getting intermittent sound and had to replace the wire connecting both sides together.  This wasn't a horrendous job, but still had to be done right (I used some cheap two wire speaker cable I had lying around).  The current problem seems to be that the left headphone speaker and pad have pulled away from the main part of the headphone.  I think the screw holes warped or broke and the assembly gave way.  Something else I'll have to repair soon, but for now these units are still working as long as I'm not careful to tug too much on that side.  The biggest reason for 3 stars though is frequency response.  I didn't find the frequency response close enough really to use for any serious recording work.  You can equalize this out to compensate, but I thought the response would be better initially.  What response is present though is ok.
