I like bacon
post #1622 of 4647

^I see....or wait ....I don't see any differences.

 

hmmmmm.... one wire is more crooked than the other.

 

Dang it you are on top of this bro. I feel bad for how much you have reposted on account of my laziness to fully search out a matter.

I think all that Elwappo was saying was simply that the "bass port" mod is still relevant to the K712, as physically it's essentially the same as the others.

who is willing to dissect these babies to prove it. spill their guts

 

 

If only someone here had taken them apart and taken pictures of them on the inside...:(

 

OH WAIT!!  Someone already did!

Yea this is what I meant, guess I needed walk everyone down the through process. Internally, aside from damping they are identical, therefore previous mods in any category could be played with.

But the Q701 variations have no real "insides" I guess. If you get to the insides you've basically destroyed your headphone! It's almost impossible to compare all the internal differences without removing the drivers.

If someone paid me to remove the Q701 driver I probably couldn't get it done and still have it be a working headphone. Maybe but I guarantee it'd take me more than an hour! Most people might not have notices but the Q701/K712 grills are almost totally see through.

 

When you expand your K712 does it have the little hole in the sides? Q701 has this but it's probably just due to the design of the plastic round piece and no real reason for being there...

 

It's enough to allow more air to get inside to the drivers though...

 

I have this crazy idea to possibly see some differences in the K712 and Q701 drivers (if they're different). If you remove the pads and outer grill you can hold the baffle part up to the light see through it. On the Q701 driver there looks like two open areas with light coming in. Maybe the K712 driver is more open. I should take a picture of this..all these models probably are just tuned different at the factory.

play with equals time

 

time equals money

 

money equals k712

 

wait a minute. :rolleyes:

 

I am on here.... of course I have the time who am I kidding. I saw these pads on ebay they look pretty nice. Maybe they will work dunno. 

 

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality

 

ill give it a try. wonder what those on q701 would sound like. but who doesn't like the new thing ya know.

I'm not sure what holes your talking about, but I think they look the same.

 

I took the pads off and held them both up to the light and I could see light shining through the white parts and through the outer sides of the grill on both of them.

Here are the 500 Hz and 50 Hz Square Wave responses:

 

500Hz

http://graphs.headphone.com/graphCompare.php?graphType=4&graphID[]=4163&graphID[]=3241&scale=30

 

See how the HE-500 and AKG K712 Pro have almost identical rise times and slopes.

 

50Hz

http://graphs.headphone.com/graphCompare.php?graphType=3&graphID[]=4163&graphID[]=3241&scale=30

 

The same goes for the 50Hz Square Wave Response.  The major difference here is that the dynamic headphone decays as it should compared to the Ortho.

 

In fact in many ways the AKG K712 Pro is quicker because quickness cues often come from treble response.  The AKG K712 Pro has more 2kHz and 6kHz response giving rise to it actually sounding quicker.

 

Reasons to buy the AKG K712 Pro over the HE-500:

 

1.) Saving at least $200

2.)  The AKG K712 Pro is more comfortable

3.)  The AKG K712 Pro has a wider soundstage

4.)  AKG K712 Pro is not made in a factory in China

5.)  There is more treble response with the AKG K712 Pro

6.)  There is more midrange response making the AKG K712 Pro sound clearer on vocal tracks.

7.)  The AKG K712 Pro has lower Harmonic Distortion

http://graphs.headphone.com/graphCompare.php?graphType=1&graphID[]=4163&graphID[]=3241&scale=30

8.)  The AKG isolates slightly more than the HE-500

http://graphs.headphone.com/graphCompare.php?graphType=6&graphID[]=4163&graphID[]=3241&scale=30

 

So other than opinion are there any measurements supporting that the HE-500 is better than the AKG K712 Pro?

 

The human hearing response and preference is not a straight horizontal line in the frequency response so many Orthos, although ruler flat, miss the mark in that respect.

 

Sure any headphone can sound "better" than another and this is called preference.  I can see reasons for owning both, but for the reasons I have listed I prefer the AKG K712 Pro.  It measures extremely well too.

 

Many Orthos I have heard sound oddly colored in the midrange because of how ruler flat they are in that frequency range.  The HE-500 and LCD-3 do not suffer from this issue as much as the LCD-2 and HE-400.  Due to their lack of soundstage and often treble the quickness cues and positioning are lost making them sound inferior at times.

 

Did you do a side by side listening test of the K712 and HE-500?

Check this photo:

http://www.head-fi.org/t/582276/q701-appreciation-thread/3915#post_9834996

 

My Q701 has two rectangular sections totally open (only one shown). The center hole is the bass port opened.

 

It'd be cool if the K712 was more open. Maybe 4 areas opened up instead of 2? That could explain the bass differences.

 

Maybe they're all the same but you never know...

They look the same to me.  Your picture you can only see 1 whole, but you said you can see 2 in real life.  I see 2 on the K712.

Thanks for the photo. So I guess they made other changes. I'm stupid, I forgot that the bass port covering is clear so it will have light coming through on each one. The port does go straight down to the center of the driver though which is interesting.

 

Those "vents" are on each side near the cups and are only visible when you hold the headphone open and move the cups inward a little. Really just tiny holes and serve no purpose probably. They're only on the side facing towards you.

Right in the middle and actually just before where the cups attach.

 

The holes are so small that it could probably make no audible change. You never know. My KRK KNS-8400 has them and so does the DT-770, but those are all closed.

Q701 and K702 are internally identical too. Only difference is the outer grill and foam.

 

I guess it will always be a mystery but at least AKG gave the K712 driver a new part# unlike with the pads.

 

Yes, really.  Why don't you email AKG rep? He can verify that for you.  I have but then what for?  cuz it won't mean much.  1 little sticker over a bass port can change the sound so dramatically like in the case of our Q701.  Who knows what else have they done in the 712.

post #1633 of 4647

Maybe it's as simple as whatever batch of "capsules" they're using actually sounds slightly different.  Or maybe not.

You just made my day.  I really had a good laugh reading your post.  and Yes, I have heard all 3, Q701, 712, HE500 and still own the Q701 and HE500.  

I bought the K712 thinking it was an upgrade from my Q701 bringing things closer to HD800.  I was disappointed so I returned it.  What a subjective hobby.  :D

Does that imply that you recommend as well the HE-500?
