Thx papamogl for bringing to light this simple but wonderful mod.

Just an FYI for those that think I came up with this mod. I didn't, but wish I had known about it much earlier!

It was posted by a guy on a German forum called "Outstanding Ears" and first posted here by "Papamogl".

I am however glad I gave it a try so more people could know about this mod. I want to hype it up as much as possible!

 

Don't forget that I did invent the Q701. :biggrin:

Original Bass Port Mod posted to Head-Fi in April 2013:

Here is the translated post (by Google) that's very interesting:

(in it he mentions it becomes more transparent and airy..first time I read the translated posted and totally agree!!)

 

EDIT:

"Now I no longer wonder why the Q701 has sent the HD800 home"

 

Had to point that out :normal_smile :

Since this was the last open question , they sound the same or not, I have now taken the opportunity to hear a K701 against my Q701 . Also, I have interchanged the cushion and back. Driven both headphones low ( M-Stage/E5 ) . The only stumbling block was the bass modification that I made the Q- model. So I can not confirm these slight differences . My two copies certainly sounded similar, but there were still some clear differences to be heard. Because of the low bass Bassmods the Q701 is of course more pronounced. But the main difference was the Freiräumigkeit , transparency and the signature " bucket " to "Phone" .

The ear becomes accustomed known relatively fast on a particular signature , which is why the center was weggeahnt presence during the tests. Because I wanted to consciously avoid using EQ that was necessary. The Q701 sounds clearly audible transparent and airy , with less fundamental, but more mids. Aufrund this really clearly distinguishable features of the two, I prefer clearly the Q701 . The highs are clear , audible through the middle , the keynote slim and due to the modification of the pronounced bass ( ala TF10 ) . The longer you listen to the Q701 , the more drops from the difference . It is then almost as if the sound falls a little into himself . While on the other hand, disturbs the moment the " Telephone " Q - model , but everything else is instantly better. If the K701 has a broad stage , the Q701 is a round lamp with still better location . The instruments and voices appear out of nowhere. In the K - model that is definitely not the case.

What also surprised me a little was the bass of the K701 , but that was stronger than I had in the memory. The K701 sounds more compact, more bass than the models that I had at home a year ago. I had also wondered about the T -90 thread , why ZeeeM when moving from "sounds like bucket " and I "sounds like a telephone " wrote . Now me is that clear ! Either there are the AKG but something like a business or effect of Q701 is actually a notch above . Now I no longer wonder why the Q701 has sent the HD800 home. Even as I have the Q701 then obtained from U.S., I noticed immediately that the Q701 clear and transparent without direct comparison also came along . Can you even read somewhere where I wrote that.

And I wanted to peddle yet Blackman yesterday. In the non- life !

I just did the mod and have been listening about 15 minutes...... I'd say it's an improvement!  Is it my imagination, or did anyone notice a very slight emphasis in the high end as well ... what I would describe as a wee bit of tizziness.  I DID listen before the mod so I could try to notice the difference.

no more emphasis in the high end for me.  To me, it's actually less and smoother and less harsh.

I have this one female vocal I listen to very often that I know how harsh her voice sounds on the Q701 and even my HE500.  After the mod, her voice has become much smoother on the Q701.

Nope, no extra treble emphasis at all for me. I haven't noticed any extra smoothness in the upper mids/treble either. I'm sure it's possible, but all my harsh recordings are still harsh. Of course they're were never very painful on the Q701 to begin with.

 

I did however notice one difference. There was a track with very harsh upper mids and this was reduced a little when I removed the foam behind the outer grill. This only applies to the modded version though. I think perhaps it made it sound a little further away perhaps? No idea.

 

BTW some of you should try the modded Q701 without foam behind the pads. The bass is so bloated! Pretty funny. Some might actually like it.

I'd really love to hear a comparison of the modded Q701 against an HD800. I'd think this puts them a bit closer to the HD800 now. I'm listening again right now and It sounds gooooood. I took a headphone break last night, didn't listen at all, and right now I'm enjoying this new sound quite a bit. I'd really like to know why AKG chose to limit these headphones from the factory.

I know this sounds stupid, but maybe due to very poor isolation. Now it's like I can hear everything. With no music playing I can hear my fridge clear across the other side of my apartment.

 

On the stock Q701 it feels almost semi-open really.

 

Sound leakage is probably awful now. I think the HD-598 has the record for the most sound leaking out of the cups.

 

I honestly can't think of any reason other than these stupid ideas as to why AKG does this.

 

Maybe they don't want people to have neutral bass, actual bass impact, crystal clear sound clarity AND a large and spacious soundstage :biggrin:

 

The bass of the stock Q701 reminds me of the KRK KNS-8400. All the bass is there but it's like you can't really feel it. No real bass impact at all. The 8400 has way better low bass presence than the Q701 though. Not sure how they'd compare now..

 

LOL it'd be funny to see a K812 next year..only difference...it has the bass port open, black with gold accents (and cable) and costs $600. They could call it the K812 EE. Maybe fancy it up with leather pads too. Sort of like the Beats "Executive Edition" :normal_smile :

Oh it's definitely better than a modded HD-800 now. No doubt.

Heh, when I read "EE" I thought of shoe width, as in extra wide... as in the sound stage :p

post #3806 of 8070

I ended up mutilating my Q701. :biggrin:

 

Much more comfortable now.

Here's some observations from A/B between modded Q701 and HD800.

 

I have tested with 2 amps: solid state (Audio-gd NFB-5) and tube (Woo Audio WA7). The results on both are quite different, so let's talk about them separately.

 

Audio-gd NFB-5, using internal DAC.

Volume matched within 0.5dB. 

Bass impact is very similar, Q701 seems to go slightly deeper.

Mids are more pronounced and harsh on Q701.

HD800 tames sibilance better.

Q701 soundstage is less precise, seems to favour extreme positions.

Vocals are more distant on the Q701.

Drums on Q701 sound a bit unnatural, adding harmonics which are absent on HD800. I don't recall hearing that before the mod.

HD800 renders the piano smoother, maybe a bit veiled.

 

Woo Audio WA7 using NFB-5 DAC.

Volume matched within 3.5dB, impedance matched.

Much less tonal difference between the two, no noticable harshness on Q701.

Soundstage is very similar on both, but HD800 is more precise.

HD800 is more detailed and dynamic, however the difference is not great.

Vocals more distant on the Q701.

Drums on Q701 still have added harmonics but it's less pronounced.

Bass impact is lower on both, but overall presentation is smoother and less fatiguing.

 

Overall I'd say that the mod has made these two tonally very similar, with rather subtle differences. The HD800 is still more dynamic, detailed and precise, but the difference is now reduced, especially on the tube amp.

post #3808 of 8070

Nice comparison! I was expecting the HD800 to sound better yet. In the end, it is 5 times the price of the Q701. :D 

 

Probably the more distant vocals on the Q701 is due a more pronounce bass after the mod.

Thanks for your observations, were the Q701 modded just sticker or sticker and foam?

I think the mods might be adding something that isn't there, but I like it. Changed from a HP I didn't like to one I enjoy for prolonged listening in one easy step, magic!

I can think of now two reasons to not do the mod (mostly repeating myself):

 

1) It makes the soundstage seem larger. Due to this, vocals that are distant due to the recording sometimes seem slightly worse. It's 100% not due to any part of the vocal range being recessed.

This only seems to occur with specific recordings with vocals that sound spaced back a tad.

 

This can be a bit annoying and occurs with like 5% of my recordings. The soundstage isn't that massive, but definitely larger than before. My guess is that it's very similar to the K702 soundstage but more accurate. Yet you get all that extra bass!

 

Male and female vocals still can sound up-front when required. I've read both now where I felt they were too forward in some songs..and then distant in others.

 

I've noticed that songs with a larger soundstage need to be cranked up higher. Even a song like "Ringfinger" from Nine Inch Nails. My amp needs nearly 45% volume on low gain with the Modi with that song.

I bet before it would be a little less.

 

2) It really does sound like it's making too much of my music collection sounds like garbage. It's annoying and how it was for me with the old DT-880 I had. Some might not like this. I don't know why there is a change.  Yeah like putting my music under a microscope.

 

Some poor recordings that are 320kbps/Lossless but yet sound more like 128kbps and sound like they have no life/really dull sounding and/or not clear at all. Some ambient music sounds good but is very muffled (not the headphone). Some tracks sounds like they have zero soundstage IN the recording. It's weird.

 

I'm listening to FLAC files of a Jpop CD that was released in 2010 and it sounds like a 128kbps recording now. It sounds like the vocals are coming from underneath a thick blanket or something. I knew the recording was always bad but not THIS bad.

 

Maybe i'm stupid but how come so many of my recordings just seem to be dull or too lifeless/boring. What causes this? I heard that the most on the DT-880. I guess it's the way it's recorded at the studio. Never experienced this on the Q701 before the mod.

 

Definitely a massive variation now between recordings. Very annoying!

 

So again, good recordings sound good and bad ones sound REALLY REALLY bad. Almost not even listenable now. I haven't felt the need to weed out my collection since I had the DT-880.

 

EDIT:

 

What i'll do is make a playlist of all these tracks that sounds twice as bad now and then listen to them on the non-modded Q701. Most music generally sounds exactly as it should. I only have issues with bad tracks.

 

One song that sounds quite bad on the modded Q701 is "Sad" on the Pearl Jam Lost Dogs CD. Lots annoying treble peaks in the recording and distant sounding vocals. Sounds recorded in a cave. Not the Q701's fault.
