The AKG K712 Pro Support and Impressions Thread - Page 79

post #1171 of 3450

Another great track for the K712 Pro is To Find A Friend by Tom Petty ( Wildflowers ).  A great track to show off the top end of the headphone and the midrange is no slouch. 

 

I updated my review of the K712 adding in a comparison of the Q701, HD650, and K712 Pro.  In the end I preferred the K712 Pro as it had more detail on the low end.  The Q701, although more airy than the K712 Pro, has some serious issues with its midrange which leads to blurring of the lows.  The HD650 sounded more speaker-like than the Q701, but it has some blurry lows leading me to sway my preference toward the K712 Pro.

 

All three are excellent headphones and it is amazing how great they all are when you have all three sitting there in front of you read to be swapped out.

 

I decided with Chubb Sub by Medeski, Martin & Wood.  The low end is crystal clear with the K712 Pro and blurry with both the HD650 and Q701.

Perhaps a note should be made that the K712 Pro is a touch less peaky in both the 500Hz and 50Hz square wave response perhaps making them a bit easier to listen to.

 

It is a great headphone to let people know how great the HD600/650 sound and the HD600/650 are great at letting us know how great the K712 Pro is.  At times both amaze me.

 

From the charts we see almost a +10dB in bass over the K702.

There is definitely less bite in the treble on the K712 Pro.  I found this listening to Iest Sexy by Shantel Vs Mahala Rai Banda.  The trumpet is a bit more tame and less ear-piercing.

 

A fun track for the K712 Pro.

 

 

Can you hear the +10dB in the bass over the K702, I mean it sounds like sound coloration compare to the K702?

lol, looks from this graph the HD800 owners cant complain on the K712 bass, maybe someone here can compare the two?

Now why does akg have to put that dreaded 2khz peak in there :D

In this area there is a lot of sound information, looks like AKG try to balance out the 2khz with the rest of the FR. If you pull the 2khz in like in the case of the HD-800 this can bring up the other frequencies like the treble and the bass, and give you the sound impression of the beatbox (in this case a fancy beatbox).

 

I'm encourage you to check this at home with some EQ and see the importance of the 2khz area.

I cannot hear below 20Hz so if the +10dB increase is noticeable it would not be by my ears.

 


The 2kHz peak ends up not being much of an issue.  The entire midrange to treble is much more even sounding than the peaky K701.  Some say the 701 etc need some serious burn in time to help loosen up the driver a bit.  My tested headphones have all been well burned in.

 

In many ways having some treble peaks is a good thing as long as they are not super fatiguing.  This is because we receive our directional cues from the treble and stereo imaging without extended treble is quite difficult.

HeadRoom claims they are similar sounding to the HD800, but that is all of the detail they give.

From the headroom FR Looks like the K712 boost is not only on the 20Hz, is all around the bass, low mids, and even in the mids area. 50-60Hz should start to be more notable and punchy. 

 

Unfortunately I didn't read the whole thread, but I was wondering if some one here already put the K712 pads on the K702?

Chicolom has. It's a few pages back, though it might be on the K702 Anniversary thread...

By the way Chicolom, putting a pad from each headphone on the same headphone sounds like a kind of wonky way to compare, it's stereo and different things are going on in each channel.  Maybe there is more reverb on one channel, maybe the mixing is different as far as ambient information?  There is a slew of issues with that testing methodology  Only way that is a valid comparison is if you switch the sound to mono.

I put K712 pads on the K702 Anniversary, but not not the regular K702 (which may be leaner sounding).

Obviously it's not ideal and having two sets of identical pads is preferable, but it's not as wonky as you think.  Both memory foam pads keep a very similar signature (unlike the angled spring foam Vs. memory foam pads) so I mainly have to adjust to one side being slightly more intimate.  And both headphones get that same treatment.  And I'm usually listening for something pretty specific and isolating something on one particular side anyways, like a specific voice or instrument coming in to hear the tone the headphone gives it.  For that, having the same pads side on that side works because both headphones are uniformly affected by that pad.  Its basically the same as comparing two AKGs where the left ear cup is pushed a little closer to your head on both (and an equal amount on both).

 

And everything I said when comparing with with that arrangement (Like the K712 being a bit smoother, darker, and more intimate) was stuff I was already hearing before.  The only new thing it help me notice was that the K712 is slightly louder overall.

Is there anything else I should test/compare/photograph/etc. with the K712?

 

I'm going to be sending it back to MLee in day or two...

Could you please compare it to the SRH-940, HFI-580, HD-800, KSC75 and SR-009? Which has the best imaging? Please also rank them according to which has the best bass.

Also, which one sounds best while intoxicated? Does it sound better than an HD-800 driven from an Ipod Touch?

 

I'd also appreciate it if you can take a photograph of it on a pumpkin. Maybe you can carve it to look like Quincy Jones.

Where's your review?

 

Nevermind, I found it.

I agree at the $500 price point the AKG K712 Pro may a bit over priced.  The biggest difference is in the pads, no surprise there, and a slight change in resonator material allowing the headphone to sound slightly less tinny than the Q701.  To upgrade from the Q701 to the K712 Pro costs an extra $200 as others here have mentioned.  Going with the Q701 and adding some K712 Pro pads will be the way to go for most people as you save $130 on average.

 

What would be awesome for AKG to do is keep the K712 Pro at $400 but offer both the Q701 and K712 Pro pads in the bundle.  This way we can tune the sound to our liking at the cost of the pads and not another headphone.

 

If you see the K712 Pro drop to $350 - $400 I say go for it, but as it stands you may be better off with the Q701 and K712 Pro pads.

 

Thanks, chicolom for keeping this thread updated about the pads.
