The Annie (and probably K712) always gets louder at the same volume levels compared to the Q701. Just due to being closed off of course. Kind of surprised about that.

 

Q701 has always been hard to drive IMO and sounds awful from any portable players. My HD-650 actually does much better from them.

 

Some say that the E17 can't drive the Q701 well enough but I think it's OK.

 

Still think the hardest AKG to drive is the K601. Even more so than the K400/K501 with my amp.

Two things I didn't like about the K 701 - some bass bloat at 100 Hz and massive treble bloat at 7 kHz. From the K 712 graph, it seems the treble bloat is as bad as it was and the bass bloat twice as bad.

 

It's a curious development from the K 501, where AKG were conscious not to introduce too much bass.

Here are some pics of the pads. 

 

Hopefully you can see the difference between them:

So which do you prefer in sound?

My definition of dry is pretty similar to the one here: http://www.head-fi.org/a/describing-sound-a-glossary

 

When I think of dry I think of it being a bit more more etched, and usually with less reverb or decay. 

Smooth is a little bit darker and rounded off.  The K712 mids sound slightly darker and more laid back than the Anniversaries.

Not sure yet.  I'm still trying to figure that out.

 

I will say I prefer the K712 pads though because they sound less intimate and more like the Q701s presentation (and I usually prefer the less intimate presentations).  Also, they are more comfortable thanks to a bit more ear room.

Wow, bigger difference than I thought with the pads. You'd think that with the K712 pads you would actually get slightly more treble and LESS bass (than the annie) since your ears are probably a tiny bit further from the driver.

Now this alone is proof kind of that AKG can have the same part #s for parts that are actually quite different. If the K712 has less forward low mids than I'd probably prefer that. I need to read the entire review again.

 

Maybe there's a few Annie's out there with pads than look like the K712? Doubt it.

 

I bought some Anniversary pads back in June and they are identical to the Anniversary photos. I wonder how people could actually get the K712 pads? If I paid $80 for some K712 pads and got Anniversary pads i'd feel ripped off.

 

Any foam behind the outer grill on the K712? Probably not worth messing with.

 

I know it's obvious now, but is the driver behind the pads 100% identical to the Q701/Annie?

I haven't been able to get the outer grill off yet.  I tried the tape twisting method but it didn't budge (I even used Gorilla tape). 

Got the grill off.  No foam.  See pics below...

 

 

I think the drivers are the same.  They look the same to me.  Here's a pic of the K712 driver:

The best way to "directly compare" them without having to pad swap each time seems to be putting one of each pad on both heaphdones.  So the left cup of each headphone gets an Anniversary pad and the right cups get a K712 pad. Doing that I can hear that the left side is slightly more intimate, but the signature between the two pads basically stays the same and my ears adjust to balance the two pads out - so it seems to work fine.

Here's a pic of the insides on both. 

 

I can't spot any differences.

I did some more comparing using this equalized pad arrangement ^ and noticed some more things:

 

 

  • The K712 is a bit louder than the Anniversary.  No clue why.  When I comparing I have to press the windows volume key a few times to balance them out. 
  • The K712 itself is more intimate (related to the above?...).  I already mentioned this earlier, just saying it again.
  • The highs on the K712 sound slightly rolled-off somehow, and the Anniversary sounds slightly airier in comparison.

Very interesting observations and photos. Seems like speculation based on part numbers was way off the mark. You probably have enough material here to compile into a new thread a la your other AKG comparison threads. Good stuff!

This is really interesting. I may have to order those K712 pads when they come available.

Excellent pictures and comments (both detailed). Thanks for your work on this.

I am able to drive the K712 Pro with my 3rd Gen iPod touch, but I have to keep the volume around 75% - 85% and even from my BUDA the inefficiency surprised me.

 

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.

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.
