Q701 impressions thread - Page 248

post #3706 of 9507
This is a very interesting mod, but I'm reticent to try it on my Q701s as I really like them just the way they are, and it looks as if the mod isn't as easy to reverse as it is to do it in the first place - sticky things never quite stick back again that well.

Besides I use the Qs almost exclusively for classical and jazz and as far as my ears are concerned they have just the right amount of everything for those genres. Other genres I tend to listen to on the move and I have my trusty HD25s for that.

Nonetheless thanks to the OP who originally posted this, and to those of you brave enough to try it out.

I'll certainly bear this in mind, and may pick up a cheap pair of K701/2s to try this out - I assume that the K series is effectively identical internally to the Qs?

I'd recommend just doing one side at a time so you at least have some kind of reference to compare it to.

 

More impressions please.

:popcorn:

This is definitely an improvement, and I still don't hear anything negative. Usually when you gain something somewhere you lose something somewhere else, but I really do not notice any negative effects here.

4. reassemble

5. repeat for the other side 

 

******I did not take it apart any farther than just twisting the grills off.******* 

 

 

I did it just like jasonb, only i used two needles. He is absolutely right: you don't need to take anything off but the outer grill!   Tweezers are essential! :D 

I have it removed only on one side (the one with xlr) and the other (right one) still has the white dot. I'm going to start listening now.

Also, I'm also seeing some inconsistent descriptions.  Some people are saying mid-bass is increased while others are saying it's reduced.  Some people are saying sub-bass is increased while others say no change there.  Some are saying the mids are fuller while others are saying they're more recessed.  You get the idea.   Seems a little fishy.

 

 

 

I'm hesitant to try it on my K712s for obvious reasons, but I'm comfortable enough going in there and messing with things that I may fool around with it if I get curious.  It's a simple enough mod and my K712s aren't going anywhere.

 

Definitely too good to be true! Totally agree with that. More bass, fuller mids AND a better soundstage makes no sense to me either. Usually when a headphone gets warmer it's just darker and more muffled.

This is what I don't get...why is it that the mids got a little fuller yet there everything sounds clearer? I've only experienced this once when modding the DJ100. At one point the mids are just so crystal clearer and not due to extra treble. I really wonder what causes this weirdness.

 

I can assure you that to my ears there is no recessed mids. If I heard this at all the mod would be reversed immediately! The differences in soundstage may give some this impression. For me good mids are a priority.

 

Then what's weird too is that the mids are full but not any more forward. They're about the same but slightly thicker sounding. Probably not like the HD-650 but I haven't A/Bed them yet.

 

NOTE: I removed the foam felt from behind the grill and the soundstage isn't as spacious sounding (with the MOD ONLY!). Pretty close but now it's closer to how it was before. Why? It allows the bass to increase even further.

 

The largest boost in very low-bass came when I removed the grill totally to test things (modded). This allows the most air to get inside. Right now I prefer it all with no foam.

 

You really just have to try it. Trust me, the rest of the signature doesn't really change! Normally more bass would ruin the rest of the signature but that doesn't seem to be the case at all. No loss of treble or upper mids.

 

BTW I definitely want to type this mod as much as possible! It's that good! :normal_smile :

 

If you do test it, Q701 pads might be best. It's possible there is too much bass for the K712 pads but I doubt it!

 

It definitely doesn't bloat the bass and it's still very very accurate. If bloated bass is IN a recording it definitely sounds that way now.

I basically think the Q701 was nearly perfect as is. I just wanted a little more low bass. If people like the stock Q701 the way it is they'll like it even more modded.

I can't say it enough but with the mod it's even better for classical, acoustic music and jazz etc. None of this extra bass nonsense will show up unless that's how it's supposed to be in the recording.

It's very well controlled. If it there was no bass boost I would have done it just for the other improvements.

 

To me the signature doesn't really change except for some extra bass. Don't ask me how this is even possible! Even with the fuller mids they're still not any more forward or recessed :confused_face_2:

 

For those that want to try it, it can be reversed with just plastic tape! The circle tape isn't any special tape that allows air flow etc (thankfully)

I just tried this mod on the K712 pro.... wanted to be the first... When I pulled out the sticker on the XLR side, I accidentally snagged a wire loose and now there's no audio on that side and I don't know anyone with soldering skills... Oh god what have I done!?? confused_face_2.gif

Edit: I admit, I was joking biggrin.gif Headphone is fine, just had to try it because tdock said he had to type this mod as much as possible. No worries guys smily_headphones1.gif

That sucks. You gotta know somebody who knows how to solder though.

I'm probably the closest to capable out of everyone I know well, except my "experience" is using blow torches to solder together rings and boxes, a little more rough process where you heat the metal you're bonding with solder and have to sand it afterwards.

http://www.youtube.com/watch?v=ukQ6OSs3dWo Is this is any good for bass testing??

At 25hz there is "stuff" on the left , right is silent. Difference is crazy between 30-50hz. Left vibrates like hell.

Somewhere between 55-60 left and right "become one" :)

 

Same result here: http://www.audiocheck.net/audiotests_frequencychecklow.php

Go down to any Wal-Mart and get a $6 soldering iron. After that just check Youtube for tutorials on how to solder.

It's actually pretty easy.

 

I did this once in the past and then learned how to do it again from help on Google and Youtube.

 

I bet it wouldn't take more than 2 minutes to get it back together.

 

Here's a decent video:

Since the wires aren't stranded you could skip a few steps.

 

This one is even better..can skip to 2m mark if needed.

 

Most likely you just need some more solder on the exposed wires to join them up. Is the wire cut at the plastic or did it just pull from where it's attached to the driver?

 

If you don't need to splice the wires together that will actually be good!

Maybe you sprinkled a little pixie dust into the open port before you capped it... ;)

Thanks for playing along, I'd like to relieve you now and tell you I was kidding. The headphone is still stock. Hope you understand, I couldn't resist, especially because I usually am the straight guy. Wasn't even going to wait this long to fess up, I had to see what you would say but I wouldn't leave you hanging. However, this video ought to be interesting and I'll bookmark it, electronics soldering skills will become useful some day!

What makes Tinkerbell's pixie dust work? And what are the results? I love the feeling of flight while listening to headphones and forgetting about myself. :akgsmile:

At 5hz I could hear the driver's popping repeatedly but didn't feel a thing.

Did the same thing at 10hz, but nothing much again...

At 30hz my ears got a nice massage.

 

What's weird too is at 1hz you can hear the right driver slowly pop. Like just every few seconds.

 

My DAC specs are 20hz+ and I doubt it'd be any different with my E17.

Haha...I wouldn't be surprised if someone did pull out some wires. On some headphones it's easier than others. The wires inside my DJ100 are super thin. I once cut that when screwing in just the cup.

 

I hate soldering to be honest. It's a useful skill but to me it's no fun at all. You should see my disaster of a Q701 Mogami cable that I salvaged from old parts. Even the Mini-XLR "boot" inside is cut in half to make room for the cable.

 

Those AKG wires are VERY secure and the only way you could pull them out I think is if the plastic piece was pressed down on top of one or you had dropped the cups.

 

If people try this they should try it without unscrewing anything but the outer grill. I have no clue how this is even possible!
