As has been discussed over and again here on Head-Fi (and elsewhere),
the Headroom FR graphs can be a useful tool at times. The information
they convey, however, is certainly not dispositive on any issue.
Yeah it's weird. This sound is not audible on my 598, HD-650 or Q701. On the Q701 you can almost hear it. If it's not on a T1 or HD-800 i'd be shocked.
It's a metallic object bouncing up and down on a table or something and the echos are reflecting off the walls. Of course this is what I think I hear
No it's not resonance from inside the cups of my headphones.
It's stupid easy to hear it on my old KRK KNS-8400, DJ100 and somewhat easy on the AKG K400. Not due to lack of bass.
I love how some subtle details are not audible on a $250-$400 headphone but I can pick it up on my cheap stuff. Wonder why.
I actually find my DJ100 and KRKs more detailed than any other headphone i've heard. The DJ100 is closed so it doesn't have that wide open/airy soundstage. Well, duh.
A DJ100 with M50 pads is pretty close in sound to what a closed modded Q701 would be like.
My goal in life is to have an open DJ100 (with the M50 pad sound). You guys must be thinking i'm nuts right about now..
I tried it on K712 + angled pads, and to me that is close enough to the Q701 in sound to get the idea. I know you will disagree if I don't hear it on a 100% Q701, but whatever.
I don't see how the K712 + angled pads could be "VERY different" from the Q701, because the difference between the K712 and Anniversary is NOT "VERY different". Therefore the difference between the Q701 (which = Anniversary + angled pads) and K712 + angled pads is also NOT very different.
The mod does make a change, and it does bring up the low bass some, but it's still somewhat subtle IMO.
I'm just not one to exaggerate differences between subtle changes in things, whether it bet with two solid-state desktop amps, two opamps, two decent dacs, etc. If the differences is subtle that's how I'll call it. I don't get carried away with hyperbole and exaggeration when comparing subtle differences. You'll notice I use the word "slightly" a whole lot when comparing and reviewing headphones.
Very very interesting!
How does the amount of change made by angled-versus-K712-pads compare to the amount of change made by the bass mod? Thanks,
It's a little hard to compare because changing the pads bring changes to the whole signature and adds a warmer fuller tonality to all the frequencies. The bass mod mainly brings up the very low bass a bit. It may have a couple small affects on the rest of the frequencies (I thought the mids sounded a tad less full) but the rest of the sound isn't affected as much.
So the pads have more change on the overall sound, and affect all the frequencies. A Q701 with a bass mod will still be drier and thinner sounding than the K712 in the rest of the frequencies.
If you isolate just the bass, the bass mod applied to a non-K712 may make the very low bass (<25Hz) a bit stronger than the stock K712. It's hard to say, because I tested the mod on a K712 - and the K712 has slightly more bass than the other AKGs regardless of what pads it's using so it's not a fair comparison. I'm not sure about the mid bass.
If you want more low bass, play around with the bass mod. It won't make a Q701 sound like the K712 though.
I'm saying that even with angled pads on the modded side it still has stronger low bass than the unmodded side but with memory foam pads (and the memory foam pads add bass).
Once you put the same pads on both sides and compare the bass differences will be more obvious.
Anyways...yes you can hear a difference in music. Not a huge difference but it's noticeable.
Finally get to hear a pair, maybe as soon as Saturday!
My Uncle Ernie is sending me a pair to demo. I can't wait! Such a nice guy.
A) Love them and want to use them instead of my modded Q701 or B) Hate them and think they're no different/better than the Annie.
If I don't like them I promise to be nice. Honestly I have a weird feeling I may like them..
It'll be interesting to compare them to a modded Q701. So far I don't think anyone has done that at the same time.
Its not impossible, or even hard, to hear a difference in that area. Lots of music has no information that low but some does. And not just electronic music, orchestral stuff that uses very large drums will have information at 20-30Hz as will large pipe organs. You can both hear it and feel it. Fire up a 20Hz test tone and tell me you don't hear that. ;) It can make a big difference when it is rolled off substantially. I notice right away how rolled off a headphone is in the sub-bass. I've found that even 5Hz can be heard although its pretty much just the movement of air that you're hearing but even that can have an effect on whether you hear the proper sub-bass atmosphere that's meant to be on the track. Alright, 5Hz will obviously have a very small, essentially unnoticeable, effect but I think you get my point. You can roll off the signal at 20-30Hz thinking you're not missing anything but for music that uses those frequencies you are in fact losing part of the atmosphere and physical impact that was supposed to be there.
