Thank you for the reply. I read all your comments about Sennheiser HD series and k612 on your site. You have written "The HD58X Jubilee is an excellent entry level headphone." on conclusion of your review. In fact I'm totally confused with this statement. As far as I understood, hd58x and hd6xx sound better than k612 pro for you and better than some more headphones too probably. But why do you consider hd58x an entry level then? I heard k612 pro before and I used to like it a lot. It sounded flat to me. I have never heard any of HD6** series before. I'm trying to decide between HD58x and HD6xx. Could you please explain how "less refined" sounds like? With undesirable harmonics? Or like different measured wave shape than the original wave shape in sound? Like for example a violin doesn't sound as it should sound because headphones change timbre of violin?K612 pro is more forward and brighter and in general less refined in the treble than most HD***.
There are also differences between various HD*** models just like there are differences between K*** models..
Thank you, I'll buy one of the hd6xx or hd58x during this discount but still cannot decide. I guess I'll go with cheaper hd58x. I wonder if higher impedance headphones respond better to equalization since they'll require less current. So could this be a reason to choose hd6xx over hd58x? I'm sure I'll need equalization or use a mod to drive these.HD58X is the cheapest option in the HD6** series. Just like for instance the HE400i or HE400SE are entry level headphones.
Entry level does not mean cheap and poor quality.
It is not as good as HD600 in the treble and in clarity (quality and amount)
It is not as 'smooth' in the treble as HD6XX and HD650
It is not as linear in the lows as HD660S
It sounds different from HD560S as well.
When you like the K612 I see no reason to look for HD series (other than HD560S) as the treble of HD series will be lower.
Smooth treble = soft texture but not subdued.
The 5khz peak in the HD58X makes the treble less 'smooth/soft' sounding. It is a different kind of treble as that from the AKG K*** series.
Some prefer AKG treble, others HD6XX treble others HD58X treble.
I have no way of knowing what you will like. Only what I prefer.
A violin will sound 'sharper' in the K612 than in the HD series. There are also differences between HD series. When you find violins a bit unnatural accentuated you can try HD series. When you find the violins to sound right in the K612 buy/use that one or consider the HD560S.
I wonder if higher impedance headphones respond better to equalization since they'll require less current.
I thought this way, I will need more current for a low impedance headphones to equalize. Somehow I can increase voltage to equalize but maybe the amp won't be able to supply enough current.There is absolutely no relation between EQ and impedance nor current.
Very neutral, almost flat sound signature. More resolution and slightly wider soundstage than 6xx. But the treble spike bothers me. I'm not a basshead or treble fanatic, but the sound is so neutral on the HD 560s that it borders or boring and clinical for me.What do you guys think about the HD 560s? I tried both the 660s and the 560s in a store and was surprisingly more impressed with the 560s. I noticed I wanted to keep on listening to them, and when I tried out the 660s afterwards I was done with them within a few minutes and wanted to go back to the 560s.
The 58X sounds a bit different from 6XX, even with EQ to make both of them flat. 6XX is way better above 1kHz, and I would say more resolving. 58X has more mids and low end, and I think the bass is faster. If the 58X is still on sale for $120-130 then, yeah I would go for it. But for regular price 6XX is a better headphone, much cleaner, but without the extra warmth and a bit of extra bass extension. If you decide to go for 58X the Solderdude's mod with K240 foam on the back of the drivers motor structure is what I would recommend (seems like Beyer DT880 foam is similar as well). Also check his measurements with current pads - the old pads sound smoother.Thank you, I'll buy one of the hd6xx or hd58x during this discount but still cannot decide.

First i had the 650, then the 6XX and i really liked them.
But i found the soundstage a little too congested, too thick, so i thought i should try the HD600. That was a bad idea, even though the sound was really natural, clear and airy, the overall sound was really lean, very thin bass and kinda glaring compared to the 650. After i sent back the HD600 i've found open box HD660s and bought it. In my opinion, the HD660s is the best out of the 3, close to the 650 sound, but more crisp, detailed, the low end not so muddy, the mid not so overly forward and theres a little bit of extra spark in the high range.
If the 600's sound lean then they are under amped. On my vintage Yamaha receiver it's 600>650>660S. The 660S sounds like a bass cannon and needs some bass/treble tweaking to sound half decent. So on my system they are over amped.
Quick question for you, I feel like the answer to this should be obvious, but at least for me it isn't. If you have a speaker tap cable and the headphone is driven right from the speaker terminals how exactly does one know what the R will be? Thanks, any information that you might provide would be greatly appreciated.That's because the K612 is a lot brighter and so the 'bass boost effect' is much less 'darkening' on a higher output R.
It does get a bit more lows and upper treble on a higher output R so slightly more U shaped which in general people like.
Where as with the Senns the midbass becomes bloomier.
