Sennheiser HD 600 Impressions Thread - Page 104

post #1546 of 17702

Hi!

 

as posted by tdockweiler, i made the same discovery.

Removing the back foam makes the HD580/600 too upper bass centered, undamped and, IMHO, just losing bass speed and quality in general.

I put denser gummy - foam circle in there instead.

The HD580 and HD600 are now about 1.5 - 3 dB lower at 90-250 Hz and THAT is enough to bring balance of the Sennheisers somewhere near neutral. The midbass hump, albeit small, is almost gone, and, frequencies around 20-40Hz are more present, by measuring it, around 2-4 dB higher in level.

The range from 800 Hz up remains unchanged, so is the soundstage size.

 

Just my 2 cents and observations, :-D

You measured it?! Can we see the results of it?

post #1548 of 17702

Hi!

 

The picture below presents measurement of my Sennheisers HD 580, with new earpads, original rear foam and denser foam.

 

MAGENTA=original, BLUE=mod

 

These measurements are cca 4 months apart, so please forgive possible differences in ambient noise, even if I tried to avoid any noises to intrude my workplace.

Please note that other differences occuring at different frequencies are unavoidable errors in placing the coupler by hand to the earpad, I'm sorry.

Saved and compared in Cool Edit Pro.

Using AKG C1000S mike, without wire mesh head, on coupler covering entire headphone earpad.

The resulting curve is compensated for natural C1000 mike irregularities and proxy effect, in addition, noise background was partially removed.

1000

Hey, have anyone ever buy a ear-pad replacement for the HD-600's? Yesterday I pulled out one of my pads and damaged them (Pushed them too hard). The tip of my ear now hits the foam padding, and it gets very annoying. Anybody know where to buy the pads for a good price that ships worldwide? Thank you in advance.

Also: Does the tip of your ear have contact with the layer of foam (the layer above the speakers)? Its a minor annoyance, and should I just change to a new one instead?

That's very interesting, thanks for sharing your measurements. I'm surprsied to see that there actually is no change at all above 200 Hz - I would have expected that a mod like this would affect the frequency response more broadly. I will try this at some point but to be honest, I'm happy with the HD600 as-is.

 

Out of personal interest, could you perhaps describe the measurement process in more detail if it's not asked too much?

I gather from your post that you have used a "coupler" to attach the microphone to the headphone. Does this coupler need to be shaped like a human ear, or does it simply need to provide a seal between headphone and the microphone? Also, what software did you use to record the frequency response?

post #1551 of 17702

Hi!

 

Thanks for you comments, Mad Dude.

 

The 200+ Hz not changing, I found it quite natural, but only after thinking about it a lot...

 

The driver breathes mainly through the center hole in the magnet, which is responsible for displacing comparatively large amount of air.

The other damping, paper rim around driver's perimeter, on the back side, is tuning the rest of spectrum, I suppose.

 

When I changed the main hole damping, then the most affected are lower regions of sound spectrum.

 

The coupler is a simple gummy-plastic circle with tube in center, which allows C1000 mike to be inserted in and ends flush with the flat surface.

The sandwich is then pressed gently, equaling more or less, the clamping force I feel on my head, to the earpad.

 

I didn't bother, unfortunately, to form a human ear shaped adapter, so the results are different from HATS measurements. But, they are very similar to some published FR graph I found on web, I vaguely remember it was in Russian and French. I then, long time ago, just googled for: HD600 FR graph...

 

Here it is:

1000

 

 

The software is CoolEdit Pro 1.2, old but very beautiful to work in, IMO.

Thank you very much for your reply! I'm interested in taking some basic frequency response measurements myself (speakers and headphones). However I was under the impression that measuring headphones was only possible with an ear-shaped adaptor piece - but judging by your description it seems to work fine without one.

 

Another point of interest, is the HD600 you measured an older pair with black screens or the newer model with silver ones? There seems to be a certain difference in sound between the two, I've had both but unfortunately not at the same time, so a proper comparison was impossible. Judging by memory alone (which isn't exactly reliable in these things), the newer HD600 has slightly boosted treble and a trifle more bass precision / control.

post #1553 of 17702

Hi, you are welcome!

It has taken me years to find a way for measuring these things, which dare I say, at least loosely corresponds with my perception of given cans.

 

Yes, it is HD580 frame with old plastic screens and old HD600 driver in there, with brass ring under diaphragm's dome.

I also own new HD600 with metal screens.

My friend, me and Kate, my wife, are in agreement with your observations. Indeed, newer HD600 sound IMO a little brighter, and the bass has more control, only the sense of spaciousness is better on the old pair.

But this is accompained by certain hazyness and uncertainity in sound placement, which is almost absent in new pair.

 

Remember, this old pair is more than 14 years old, I sometimes wonder why so much work, and fun around such a old thing. I never felt urge to dump these Sennheisers and buy something for replacement.

I have AKG 701, 401 and Sennheisers HD650. I heard more than once the HD800, fine, great, but I feel more happy with tamed treble than with hyped, like on the HD800.

 

I think I also kind of like retro things, like my MiniDiscs, Palm and even Windows 2000.

Can you guys give me a comparison between the Sennheiser HD600 and the Sennheiser HD598?

 

I'm borrowing my friend's HD600's for a week and I'm wondering if the price gap is equivalent to the sound gap.

 

Looking to buy a $200 range headphone in the future and looking at the Sennheiser HD598 or Shure SRH940.

post #1555 of 17702

based on the artists you have listed below i think you would enjoy the 598 more, not that the 600 sounds bad with those genres, I find that I would prefer a more forward upper midrange for rock and the 600 is all about being laid back

Also: When you guys wear the headphone, does the tip of your ear have contact with the layer of foam covering the speaker? Mines does when it firstly doesn't. I mean it was only one month, I don't want to change the pads.

 

Check Headroom and TTVJ if they ship outside the US. Some eBay sellers ship out of N.America too so you might want to wait for pads to come up from time to time.

Can't resist to suggest a grado/alessandro... I'm seeing a lot a lot of good deals on grado's on the FS forum recently.

All IMO...

 

HD-600 has more mid-bass, is much warmer and fuller sounding. It also has a much smaller soundstage than the 598, but better imaging perhaps.

The 598 I like because it has more forward mids and is a better match for my genres. I love it for female vocals and asian pop music. I do love the HD-600 for Pearl Jam and other rock music though.

The 598 is a little more fun and engaging to me. For MY music.

 

The HD-598 sounds like it has more treble than the HD-600. I think Sennheiser said it doesn't, but it doesn't seem that way.

 

It'll all come down to preferences. HD-600 is better for some.

 

BTW I do find the 598 to be still quite good for harsh and fatiguing garbage tracks. It seems to take the edge off them slightly. Maybe not like the HD-650..

 

Also..the HD-600 does seem a tad less grainy than the 598, but my 598 is recabled with cheap Mogami and it clears up a bit. Same signature.

 

Now the HD-580..that's actually closer in signature to the HD-598 IMO. Slightly more aggressive in it's signature past the mid-bass than the HD-600. Same driver..

 

Also..it's interesting that everyone says the HD-598 has forward upper mids yet they don't show up in many graphs (just like my DJ100). I love my forward upper mids!

I had the "terrible misfortune" of recently getting both the HD600 and SRH940 at roughly the same time.  I keep asking myself which is better.  I'll A/B a track between the two phones.  Whichever I'm listening to at the time sounds better!  I play the HD600 out of a E09K/E17 combo, and the 940 just from the E17. I have to EQ the bass up a notch on the HD600 to match the 940.  I have to EQ the treble down a notch on the 940 to make it listenable.  My opinion in summary:

 

The HD600 is more neutral and forgiving on tracks that are not the highest quality. They are more "all-purpose"

The SRH940 has the most incredible detail retrieval I'VE heard in a headphone. I often find myself listening in awe to the detail... rather than just letting the music flow around me.

 

(I haven't heard the 598)

 

They both take EQ very well.  You can't make a bad decision between those two.  If someone put a gun to my head and I could only have one, I guess I would choose the HD600 for being more "all-purpose".  OTOH ........

post #1560 of 17702

I'm not one for many words in these debates but I've owned the HD595 and the HD600 and had extended listens to the HD598.  While the HD598 is an advancement of the 595 the 600 is a different class of headphone.  Draw your own conclusion when borrowing them because everyone's opinion is different.  Personally I find the HD600 one of my favorite headphones (and my #1 from Sennheiser...yes more so than the HD650 and the coveted HD800s [never heard the 700s]).  I live near Jude I've played with my fair share of cans.  It's really a do-it-all type of can and won't break your wallet.  :)  Just make sure you get something to drive them well or they truly are an epic disappointment.  

 

Anyways, that's my "opinion".  Happy listening.  :)

 

EDIT: I saw your listening choices and we jam similar beats.  Lead singer from Rise Against sounds epic on the HD600.  Try the track Savior and you'll fall in love with them.  Anyways, I love the HD600s with those groups and then I save my techno/trance and movie listening to my bass beating Denon's lol.  HD600 do well there too but it's just "not the same."
