Nice! Another lurker starts posting
I think I'm going to buy a pair of K702, once I can find a dealer that will promise to only ship me the flat headband version (several emails sent).
If you've been reading here a long time you know that these are likely to see sound improvement from being "burned in" (aka "run in", "broken in") for at least 100-200 hours. I know I heard a difference with my old K701 and my new K712 has developed nicely with around 150 hours on them. Bass seems tighter and a bit of that edge on the very highs should tame down just a bit.
"Neutral" should be that an overlay showing the original source material and a recording of the speaker/headphone that reproduces it are a very close match. This is difficult for any chain to actually accomplish and extremely tough with testing headphones in particular. Me? I look at frequency response graphs like those from innerfidelity and headroom... If the highest bass peak is higher than the treble peaks then it can be considered to have a bass emphasis and vice versa.
I've included a graph comparing the K702 and the K712 (that I recently got). If you look closely you can see that on the K712 the highest level on the left side of the spectrum is nearly +3db higher than the highest level on the right side and approximately +9db higher than the very far right peak. The K702 has mid/bass that peaks only +1db higher than the highest on the right and +5db higher than the highest treble shown... it will probably provide the "flatter", more "neutral" listening experience and the K712 definitely sounds like the more bass heavy of the two. Just my US$0.02 worth!
I've never tried a K70X with a bumpy headband but the flat headband on these is not necessarily comfortable . I do get hot spots every now and then and have to re adjust just like my Grados.
We'll see if they really improve with Burn in X3.
Hmmm But how do I really know if that's how the source is supposed to sound? I was not next to the engineer.
I love looking at graphs, too! :3 they give me an idea of how the headphones will sound.
Also, I've been thinking... If AKG designed the pads to be 3D (Thicker on the back) so that the cups would sit at an angle to get a better soundstage... BUT the temporal bone is a bit "lower" than the Zygomatic bone (had to google the names.. lol) does it mean you have to slide the cups towards your face to get the intended effect? Or am I over analyzing this? .-. Some one else in this thread noticed a change in sound, too, specially in the treble. Thank you! ^-^
