Summary: The Denon AH-D600:
First thing you notice when getting the headphone is it's fantastic packaging. From the outer sleeve sleeve to the actual fold box, everything speaks quality from a reputable company.
Pros: Bass extends very low and has great clarity, sounstage is wide, comfy phones, quality build, packaging and accessories are excellent.
Cons: Mids are slightly recessed, not very portable but has cable for it, it LOOKS like beats, somewhat heavy, full MSRP
Summary: I'm in a good place. Three days ago I bought a pair of Monster Inspire headphones, which I find to be tremendous. However I let my wife try them on and I could sense a tinge of envy; I knew that I needed to have two pairs of premium cans in the house.
Pros: Enveloping, rich sound. Not shy on bass, but still tight. Massive, comfortable earpads. Great in-line microphone cable as well as "pure" long cable.
Cons: Much heavier and bulkier than Monster Inspire, MSRP is too high.
Summary: I think that the old D2000 sounds better than these, they are not bad at the current pricing but they do not sound very natural in the treble and also the midrange is a bit lacking, the size of these beasts is impressive and so is the bass and soundstage, I like the big sound of them, just shame...
Summary: When I bought these headphones about 2 months ago, I didn't expect much and I bought them without trying them out. It was an impulse buy to be honest, they were on a considerable discount and I just could not resist it.
Pros: Clarity, resolution, detail, smoothness, deep bass that is in general tight and well controlled, very easy to power, great quality cable, value.
Cons: Slight bass resonance, slighlty "off" tonality in the mids, highs can be sibilant sometimes, too big and bulky, resulting in loose fit.
Summary: So I got this headphones used on Amazon for €170 which I think is a pretty good deal. I mostly listen to alternative metal and rock. ( Korn, Deftones, Radiohead, System of a Down, etc.. )
Pros: Easy to drive, Tight and controlled bass. Very soft ear pads though can get hot over time. Nice soundstage.
Cons: Tooooo big. Sibilant. Mids are slightly recessed. Very "V" shaped.
Summary: Bought these used off the FS forums. I had been interested in these since release, but due to negative reviews did not think it was worth pulling the trigger when they sold for $500. At the price I purchased them at, I am quite happy with them.
Pros: Comfort, solid build, not fatiguing, fun!
Cons: MSRP $$$, Earpads can get heated, weighty - not suitable for portable use as Denon intended
Summary: I went into a local business that had these on display, and after trying them I decided I enjoyed them more than enough to get them . . . assuming I could get them substantially under MSRP which I did. Let's get started on the good, the bad, and ugly.
Pros: Musical bass, high separation for closed can, sparkly treble without fatigue, looks, removable cable, imaging
Cons: High MSRP, bass slant may be too much for some, weight, not suited for small heads.
Summary: I recently purchased the D600's and after a few of weeks of almost non-stop listening to them, can say they are hands down the best headphones I've ever owned.... or heard.
They have the tight, low end bass response coupled with good mids and highs I've been searching for in my ideal headphone.
Summary: I agree w most reviews that these does not warrant the $499 MSRP. (Then rather opt for D5k, D7k).
BUT - at the +-$230 range I got them at (Amazon warehouse) - these are VERY good value for the money.
Pros: Comfort, bass, 2 chords (1 x portable, 1 x desk), balanced (with a good amp)
Picked these up for a special price after listening in store and liking what I heard very much. A clear, clean sound with a really fun bass response. A very different sound compared to my HD 800 and I liked the idea of a headphone that made you tap your feet.
Pros: Extremely comfortable. Clear, engaging presentation. Easy to drive.
Cons: Lack of coherency. Midbass resonance. Not the best choice for the MSRP. Design is maybe a bit dull?
