Pair these headphones with a mono mix cube, and witness your mixes going to the next level. Super comfy too. Had an issue with the left can becoming dislodged, and Sennheiser had excellent customer service and replaced them effortlessly.
"Last year I went on heaphone pilgrimage in New York city. During my extended stay in the city, I visited several giant headphone listneing stations located in some of the world's largest high end audio/video/photo/electronics stores. Between all my visits I got to listen to and try almost every headphone that is manufactured worldwide. Every time I put on the Sennheiser HD600's it was obious that they were in a league by themselves. Even the higher end Sennheiser headphones didn't sound as smooth in the extreme treble area but also extremely detailed and clear. The bottom end was extremely accurate and tight like none of the other headphones.
What really surprised me was the price. It seemed that $300 is the point where the sound quality stops and your dollars keep on going. No other headhones in the $300 - $3000 price range sounds as good as these"
These headphones are really great. I have 5 pairs of headphones and now these are the only ones I use on a daily basis. I got my pair for 100$ off, and if you are on a budget, I'd wait for a sale.
