True. I wouldn't call them truly reference. The K612 is what I consider reference, if you want something very linear and balanced, that's the AKG to get. The HD 600 is another headphone to look at. The DT 880 has a bit of a treble spike so not so sure about it.

A K712 V shaped , really ? :confused:

It's somewhat v-shaped, it's not overly v-shaped though, but the fact it's slightly v-shaped becomes rather obvious compared to the K612 which is very linear and balanced sounding from the bottom to top. I wouldn't say it's a true v-shape, rather more of a W-shape as there is a boost in the midrange. The K712 is the better and more refined headphone but in terms of linearity and balance the K612 has the edge.

Then revert to Q701/K70X Pads or even try the K612 Pads on K712 Pro to get "linearity" back ?

I dont have the Q701 pads, and I like the sound of the K712 more than the Q701/K702. The K612 pads just make the headphone too treble oriented and don't have enough bass. The Q701 has a similar curve to the K712 just less pronounced. The drivers are different sounding on the K612. Anyways the K601/K612 is more linear than the entire K701 family. I bought the K712 knowing it was going to be less linear than the K612.

*Never take graph too serious though*

That is true, it's not best take them too seriously. They are good for having a general idea of how the headphone may sound though. I'm only commenting on it because I can hear the curve on my K712.

I just received a brand new Beyer T1 ($760) and they are great. I also have HE-500 that are great. What's really impressive is how my K712 hangs right there with the other 2.

 

AKG really nailed it with K712 IMO. They are some of the most balanced cans I've ever listened to, much better than my Q701. I am not a graph reader or believer. Audio is just too subjective and obviously everyone's hearing capability is different.

 

The K712 is stellar with Emotiva MiniX A-100 speaker taps and Lyr too. The bass control is unbelievable. Best AKG I've ever heard.

 

I could easily live with a $380 K712 and $220 MiniX............champagne audio on a beer budget. Great job AKG!

 

I've listened to many headphones at this point and have concluded the point of diminishing returns for my ears is $700, so it's really great to see K712 so strong.

Well said.  The HD800 is my reference can so far, and in lieu of not currently owning it anymore, the K712 has yet to disappoint me.  The well balanced sound as you say is it's real strength.  Even after listening to a bunch of other high end cans at a recent meet, I don't have that immediate upgraditis afterwards.  It scales well enough that I can upgrade the front end more first.  Even after hearing the K812, it's nice but certainly not 4x the price nice.  It's not that the K712 does any one thing amazingly well, but does everything nicely, without any seriously detracting faults like the older K701/702

 

I've had the Resonessence Labs Concero HP for a few days now and it's also been a great match so far with the 712's.  It's really surprising how well they scale with upgrades.  Can't wait until I'm able to fix my Super 7 though.  K712 really sings with it.  I also listened to it at that meet with a Moth Audio 2A3  (Same designer as Eddie Current) and a high end Cary Audio SACD and holy moly that was amazing.  You really forget you're wearing a sub $500 pair of headphones.  Garbage in/Garbage out I suppose.

I am not someone who is [not a student], so buying these is only a dream for now.

 

However, this thread made me interested: how are those graphs actually made? I am a firm believer that when properly worn on your head, the headphones' true sound could only be measured by human ears (my ears). What microphones are used? How?

post #2860 of 3608

They put a microphone in a dummy head. The headphone is then worn by the dummy head. There will be some programs recording the frequency received by the microphone. Depending on the loudness the microphone received, it will be measured. something like that they do.

 

PS: No microphone are neutral, therefore, measurement may not be the most accurate object to measure sound quality. It will only tell part of the story. Things such as soundstage etc cannot be measured. In fact, our human ear may not be neutral through out the frequencies too xD

Hmmm... use the most neutral microphone you can get, and use it for all the headphones you measure? If I'm not WRONG, pink noise can be used to test neutrality of equipment.

yeap xD but I am not the one who measure to be clear haha I know Tyll from Innerfidelity does that not sure who from headphone.com does that though

When it comes to (°_°)phone measurements, I used Sonic Sense Pro Audio to choose my K240S. If not for them, I would not be able to get under 100$ pair that is this good. I guess I have a question here... for another thread.

 

And when it comes to poor man's measurements, I use several tracks by Stewart "Awesome" Copeland, which feature ALL frequencies and a ton of instruments (the man LOVES  electronic overdubs). If I cannot hear all details more-or-less clear, the pair was not worth the money.

 

Anyways, fell free to continue discussing an awesome pair that I could not afford for a long time.

I think you are spot on with scaling and sourcing. I use either a Pioneer DV-58AV optical player (SACD, DVD-A) with Burr-Brown PCM1796 DAC through the stereo analog out or a Squeezebox Touch connected to a Bifrost with a glass Toslink cable to stream FLAC. Those either hook to the Emotiva, a Lyr, or Asgard 2. Right now it's been hard to use anything but the Emotiva, it just brings so much weight to the audio. The bass control is amazing on T1 an K712.

 

The K712 is simply amazing at its' price point. I was really big on the Q701 before getting them. AKG really pulled off some kind of magic with the driver implementation. Anyway, enjoy your journey!

post #2865 of 3608

I have the Q701 and the K712 and find the K712 superior in every way except maybe, maybe soundstage.   I'm very surprised to see some people saying they can't tell K712 apart from Q701.  Maybe hooked up to an iPhone or low powered source, but certainly not hooked up to my Asgard 2.  The bass is much better, and they're a bit less peaky and overall are less fatiguing.  In terms of comfort the K712 mops the deck compared to Q701
