The AKG K712 Pro Support and Impressions Thread - Page 184

Let's not forget that the Annie and K/Q70x don't sound the same UNTIL you add the Annie pads to the latters. The flat memory foams add a significant amount of warmth and fullness to the sound that the Q/K lacks in comparison.

Here are a few tracks that I really enjoy with mine.  Give them a listen.  The K712 Pro really does not do well with heavy rock, but just about everything else sounds great as long as it is recorded well.

 

List:

 

Armik:  Casa de Amor, Flames
Marcus Miller:  Renaissance, Detroit
Peter Murphy:  Love Hysteria, Time Has Got Nothing To Do With I
T.H.White:  The Private Spotlight, Separations
The Doors:  Essential Rarities, Queen Of The Highway

 

Thanks for the reply. It's not that I feel I'm missing a certain synergy (just trying to better define and understand it), but I suppose I'm more curious to what everyone's preferred setup is.

 

My current amp/source inventory was purchased largely because I got good deals on the Aune T1 and the O2 combo. Plus I could roll tubes on the T1. Cheap fun that works with a wide variety of headphones. Now it may work, but that doesn't translate into a good pair with, again, synergy. I don't think I'm a big fan of the O2 and K712. The T1 seems to be a little better, but the amp on the T1 isn't all that great.

 

Currently, I brought the O2 and K172s to work and I'm using Google Music. Some of the music I've uploaded is a  variety of mp3s and some FLAC. I'll try to find those tracks and see what I think. I'll listen here, then bring the cans home and try those again with the T1.

I've bought the K712 almost 2 months ago (with magni/modi). Since then the price of the annie dropped to the same price I've purchased the K712 for so I decided to trade them in for the annie. I disliked the treble spike at 7khz (for the rest they're pretty amazing), I'm hoping the annie is more like the signature of the K/Q701/2 who don't have such a big spike at 7khz. Will post my thoughts about the/any difference between them once I receive them.

Exactly this. ^^^

This appears to be the consensus reality. wink.gif

I don't think they're the same drivers, because they seem to handle sub-bass tones better than the delicate k701's. Also, the graph on InnerFidelity shows lower bass distortion.

I don't have a lot of time on these yet, but both of these work fairly well. Having said that, I'm still planning on an upgrade (I use the word upgrade loosely here). I was looking at Schiit A2/Lyr or maybe an Audio-GD. Maybe a Project Ember. I, and unfortunately my wallet, is on the loosing side here, like to experiment.

 

Just curious to see how you've achieved some sense of synergy. At least through your ears.

 

I think the K712's are terrific, but they've only shown that with AC powered amplifiers.

None of my (six) portables (including the O2) has made them 'sing' as they can.

I agree - it should, but sometimes it just isn't.  Not sure why.

Agreed.

More on power IMO. I like it with E07K for warmth but for far better sound, the E09K is the one I go to. xD

Does anyone have a solution to the earcup creak on the K712? I tried creating a buffer between the joint with electrical tape, but it didn't work. I'm currently deployed to Afghanistan, so I don't have a lot of resources available right now. Any ideas?

It's to the point now that I have to stay completely still when using these things or it sounds like I have a pair of crickets on my head. It's very frustrating. Anyone posting frequency response graphs for the headphones needs to include the huge hump at 7khz caused by the constant creaking!

You might try some lithium grease.  It's safe for plastics and might silence things a bit.  They sometimes use it on M4's, so maybe you can find some in Afghanistan.  Try it out on some test plastic first, though, to make certain it's pure.

 

PTFE (teflon) lube is an even better choice and I've read of people using that on weaponry, too.  There are approved lubricants for military issue.  If you can find some and it turns out to be lithium or PTFE, that would do the trick.

 

Just be careful, though, because a petroleum-based lubricant will dissolve the plastic, eventually.

Question for you 712-ers out there. 

 

Was it ever confirmed that some late K702 anniversary sounded like the K712?

Nope... The debates goes on >.< some say they are same while some say they are different but similar in signature. Some say the K712 are better.

In fact, there are some headphone which don't measure well but sound excellent! The K712 for example. I was thinking of harshness in it but until now, I don't see anyone complaining about it. Objectively, you want to make sure everything perfectly neutral however, subjectively, we want something different, some wish to be bassy, midrange focused etc etc

 

How do the K712's not measure well?  They have a bit of a dip around 1Khz, but other than that they look pretty good compared to most headphones.  If anything, they could use more of a high frequency boost to sound "neutral," according to the diffuse-field equalization chart.  My UE600vi's are ruler flat from 10hz-1khz, and they sound great, albeit a more "relaxed" sound like one would expect from Sennheiser.  

 

I completely understand people wanting a different sound.  I just think swapping amps is a silly way to go about it.

My view: our current tools for measuring these phenomena simply don't do a complete job of explaining them.

Hrm, darn. 

 

I'm borrowing a pair of K702 anniversary, so now I have 2 pairs on hand for about a week. Mine is early production, the borrowed one is very late. Notably different sounds on them.
