The AKG K712 Pro Support and Impressions Thread - Page 155

post #2311 of 3258

Yeah, actually no mistake per se in your labels, just could use the clarification. Thanks for the link, looks like good reading. Skimming a bit, here's the relevant bit:

 

Quote:
Free Field – The HRTF when a sound is emitted from a source directly in front of the head in an anechoic environment.

Diffuse Field – The HRTF when sound is coming at the head from all directions simultaneously.

Independent of Direction – A rather recently developed HRTF to measure real world sounds in less abstract and highly conditional situations than the two cases above.

 

I would prefer to have an HRTF calibration curve for the special conditions of two speakers placed 30 degree of axis as that is what the headphones are trying to simulate, but no such calibration exists. After lengthy discussion with the applications engineers at Head Acoustics, the Independent of Direction HRTF was picked as the most applicable for my purposes.

 

And something else I found:

Even if the raw graphs are the same, it's irrelevant to my point.

 

I am saying the regular FR as presented to the public is quite different. Regular (not raw) FR below:

 

On innerfidelity the Q701 20Hz response is 5db down from 100-200Hz peak.

On innerfidelity the K712 20Hz response is 3.5db down from 100-200Hz peak.

A comparative difference between headphones of 1.5 db in 20Hz roll off from 100-200Hz.

 

On headroom.com the Q701 20Hz response is 9db down from 100-200Hz peak.

On headroom.com the K712 20Hz response is 4.5db down from 100-200Hz peak.

A comparative difference between headphones of 4.5 db in 20Hz roll off from 100-200Hz.

 

If they use the same raw data then they are massaging it quite differently when presenting the regular FR to the public.

Do the pads on these things come off, can see mine getting clammy quite soon. Don't want to wreck them.

Yeah.  Very easily.

Twist or pull, they look very snug against the frame. My Ultrasone's just twist off, sometimes by themselves.

You twist.

 

They're attached via a bayonet lock.

Has anyone ordered replacement pads yet and actually received K712 pads and not Annie pads? K712 are a little deeper with taller "walls".  They go flat less.

I'm thinking of ordering K712 pads but AKG parts keeps saying they're all the same.

 

Isn't it kind of wrong to send a person with the Anniversary some K712 pads since it changes the sound (a little)?

 

If I was one of those who paid $500 for a K712 and got Annie pads i'd be kind of mad..

Thanks, that puts my mind at ease. Last thing I want to hear is a crack while adjusting 320 quid headphones. :smile:

Did a review and short comparison to the HE-400. http://www.head-fi.org/products/akg-k712-pro/reviews/9953

Was just comparing both of those side by side one last time before I ship off the 400's and saw your post. I'd agree with most of the things you say. Definitely like aspects of both and prefer some parts of one over the other. I find that the K712's make a lot of my badly recorded songs show just how bad they are, but with the good recordings, they are really great. The HE400's seemed more polite with bad recordings. I definitely prefer one headphone over the other for different songs, but I can't justify owning both anymore. The biggest deciding factor for me is the comfort on the AKG's is miles ahead of HE400 for my particular head.

 

The biggest difference I notice when switching between the two (SQ wise) aside from the obvious openness is how much more forward the vocals are on the K712. I always felt the HE400's were a bit to distant making them feel dark when compared. I also noticed some of the strange sounding vocals in certain songs on the HE400's that you mention. But man can HE400's do bass well, its rock solid. HE400's felt like they had a more technically capable driver. The ortho driver just gives it a more visceral experience.

 

Overall I prefer the freq response on the K712, but like I stated I feel that the HE400 is more capable. So I'm sticking with the K712 for it's preferred response and comfort. @spittis Just curious as to which one you prefer after your side by side?

 

Wish I could have a HE400 driver in a K712 tuned more towards the K712 freq response. That would probably be my ideal headphone :P.

That matches my experience... K712 Pro remain the best in up to 500USD price range IMHO.

Yes the HE-400 is more forgiving with bad recordings. I might have forgotten to write that in the comparison.

 

I don't really have any comfort issues with the HE-400, but they do feel very bulky compared to K712. It's not a deciding factor for me though. I'm opting for the K712, they are overall better IMO. The only thing I really wish I could keep from the HE-400 sound signature is the way they reproduce drums, it's just awesome.

I Just received my pair of AKG K712 pro and I have to say that i am not a audiophile but I enjoy Music and a GOOD headphone. It is kinda of my first really nice headphones 

 

I bought many "Gaming" headphones in the past but none of them could compare to the K712 

 

Astro A40 "Good"

Astro A50 "Bad experience in general" 

Corsair 1400 "The worst of them all"

Bose 2 of them One earpad and the other one I really could not remember the model 

and before the K712 i had the Audio Technica ATH-M50

 

I am enjoying the AKG it is really nice headphones paired with Asus Xonar Essence STX 

 

Thanks and Best Regards

MrShooter79
