"Decent buy"4.5 starson by aaron.tester
Pros: Decent across the board
Cons: Not many, unless you intend to nitpick
Summary: Argh... I'm horrible at giving impressions. I'm better at listening only though. Pardon me for my limited headphone-description vocabulary.
My first impression of the K601 is that it is rather musical. I have done some brief listening to both the K501 and K701 (both of which I found great).
It's something like
K501 -> Lean, tight bass. Great, wide soundstage
K701 -> Nice across the board. Really black between the notes
The K601 is somewhere in between. There's still a nice soundstage, though, based on my failing memory, it's slightly smaller than that of the K501. Bass is definitely more present than in the K501.
K501 -> Thud
K601 -> THUD
But of course, if
k601 -> THUD,
Creative HQ1700 / Audio Technica FC7 -> TTTTTTTTHHHHHHHHHHHUUUUUDDDDDDDDD
It's "greyer" between notes than the K701, but still rather nice. Details are great. I can hear some stuff that I didn't hear before, on the UM1, etc. However, it's not as good as that of the K701 (I guess you get what you pay for) Overall though, the K601 is rather quick, but with decent decay, especially if the track was recorded "live" in a big concert hall. Cymbals sound great for some apparent reason.
I'm currently pairing it off with the Marantz CD5001, ampless (which is a pity, since the K601 is a 120 ohms headphone) so my impressions may differ from others. Anyone wants to offer an amp or DAC?
I believe the K601 has not really taken off in headfi, but it does sound good to me. I tried the DT880, which is supposed to be in the same price range as the K601, and found it a tad bit clinical and dry compared to the K601, though it may have been due to the fact that I was using the DT880 with a PCDP. The K601 sounds much better on the CDP than the PCDP though. Anyone for a K601 smilie?
PS: The K601 has had around 50 hours of burn-in already.
