Pros: extremly good comfort and isolation, clean clear sound, dynamic, very punchy, easy to dirve
Cons: slightly sterile, bass is accentuated in a certain area
Look and Build:
Though different from D5000's classical design, the modern look is actually quite good. The headband along with the outer shell is very low-profile kind of black color. With some bright parts it is not overly dull. The somewhat white inner ear cup and logo look pretty good to me. The sewing on headband and earpads are very neat. Plather parts are nice, hope they will last. Fabric-covered cord and carrying bag feel very good and solid.
Comfort and Isolation:
Insanely comfortable. Really and easily the best I ever tried. Room inside ear cups are pretty large. My ears very slightly touch the walls inside but never the drivers. There is only very minor pressure on my head. With the headband adjusted to the right length I don't feel any weight of the headphone. The ear cups can only be adjusted slightly but they provides 360-degree articulation. They move around in any directions. I can very easily find the perfect-fit position. Earpads are so soft. They also provide great comfort. If I have to pick a drawback, the earpads probably have too much friction on my skin. Isolation is very good, far beyond my expectation. There's a typhoon outside my window right now,but I can hear almost nothing with the headphone on my head. Even with the window open and the pouring rain, I can hear my music clearly. It seems that the high frequency noise is mostly blocked outside. Really the comfort and isolation are off-the-chart good.
D600 is energetic and fun to listen to, yet non-fatiguing.Basically balanced sound. I do feel the bass is somewhat accentuated in one area, though it says on the box 'tuned to a flat EQ.' That makes bass drum and string bass stand out and emphasized in a way. That emphatic bass part is really excessive to my ears and prevents it from being completely coherent, but that may be a personal taste matter. Bass does sound good on some tracks. Rest of the spectrum is very clean and clear sounding. It's slightly cold and fast sounding. Vocals are fine but not particularly inviting. I would like a heftier mid-forward sound and slight warm-tilt. D600 is slightly sterile to me.(HE-500 is my choice and my main phone) Separation is good along with good imaging and location. Soundstage is not like very wide and deep. But I think it is pretty coherent with a good shape and moderate sense of space. Dynamic is good. With accentuated bass D600 is very punchy. D600 is doing a good job here.
Comes with in-line three-button control,carrying bag and Denon Audio app you can download for your Apple devices and android devices, it is obviously made for you to take out. And it works very fine with my Sony Erricsson mobile phone. However the size of the headphone is actually pretty big, I wouldn't wear it on the go. Taking it from places to places should be fine. The design is not as fragile as D2000, which I owned, but still is not tank-like robust. Some care could be needed. Given the performance and new type of sound, you should audition it whenever you can.
