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: 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: 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.
Conclusion: They're bonkers headphones, they really are. We'd never claim they'd suit an audiophile, because they quite simply push the bass too hard to be considered for people who want a pure experience. But what they are is amazingly comfortable and beautifully clear.
Pros: Stunning bass, lovely overall sound, comfortable, perfect for watching TV and movies
Cons: Headband a little loose on normal-sized head, devilishly expensive
