Rating : - Reflection after 12 months use
I normally don't write reviews, but for these headphones I'll make an exception. They are the ultimate. I have been using them basically non-stop for 12 months with a variety of music at a variety of volume- Jazz mostly but also metal, classical, j-pop, prog rock, you get the idea.

I thought I would buy these exclusively for studio monitoring, but they work so g*ddam well that I use them to engineer albums too.

They worked great right out of the box, but the icing on the cake is that they actually work /better/ over time. That is, the bass settles and sounds more like that which you would hear out of actual stereo studio monitors.

I recommend them to everybody regardless of musicianship. They're less than $100 for goodness sake, and the durability leads me to believe they'll last for decades. If my pair breaks for some freak reason, then I'll have no qualms replacing them with an identical pair.
