Fantastic sound and very comfortable

Untill they break.... and break.....

I was incredibly impressed with the sound of these headphones, they are probably the nicest headphones I have ever heard. Everything from low to high is incredibly clear and represented, and the transient response is very revealing for headphones.
Unfortunately, they keep blowing and distorting bass notes. My pair have blown twice in 6 months and even though Beyer have repaired, I am thoroughly unsatisfied with this. I've never had HP's blow on me in the past and these have only been plugged into the dedicated headphone out of my Focusrite Saffire audio interface.
They have been sat on the shelf as I have not had the time to post them to Beyer (again)
Despite my initial satisfaction with their (truly awesome) sound, these headphones were not worth the money and my low score reflects my disappointment.
