The AKG K712 Pro Support and Impressions Thread - Page 248

post #3706 of 3718

They do post all those specs... and it's the internet so of course it's YMMV if it's his opinion. Sheesh. And he's right about mobos in many instances...

 

And to Fluffy, the K712's are more neutral, and the X2's more warm and bassy. Both great and well loved, just decide which adjectives strike your fancy the best if your wallet has already been handled :D.

Sorry to go off topic.

 

The same is said with motherboards. There is a small niche of high end PC users that make up a small portion of the targeted consumer base as well. In turn you get high end PC components that do have the capabilities to support a quality set of cans. Not many but they are there. Here is an example. I own the below and it is capable of driving a good set of cans and they also post real specs of the chips and caps that are used.

Now back to the topic. :)

What's the output impedance?  How about the mW into a 250 ohm load?  Frequency response over impedance?  Volts?  EMI shielding?  

Looks like a nice motherboard.  I'm an Asus fan (my last half dozen mbs have been Asus, currently Sabertooth 990FX rev 2 myself, with separate sound card), but what I said remains, untested.  MB manufacturers in general don't care about higher end head phone users.  Why would they?  Most either use a separate sound card or separate dac/amp.  What is the marketing genius behind spending any more than absolutely necessary (probably $2 or $3) when most of this niche won't use them anyway???

What most people here seem to fail to understand is that a 3DB difference is TWICE the power.  Yup.  You read that right.  Twice the power to make a +3DB increase.  Google it.

This means that a headphone that is only sensitive to 94db is MUCH quieter than a 100db can with the same power on tap.

While that is correct from standpoint of power, 3dB is not that much of a difference in perceived loudness. Yes, 6dB is quite a difference not easily made up by providing more power (given the 4x headstart the 100dB headphone has).

 

Normally 3dB is a value perceived as a 'difference' in loudness, 10dB is roughly perceived as double loudness. Logarithmic scales are a bit counterintuitive... plus its dependent on frequency and sound pressure level as out hearing is not only logarithmic but also differs on these two aspects (i.e. 3dB in bass on low level is next to nothing while at ~1kHz its easy to spot etc.)

 

In summary I don't think that the K7.. series does indeed require that much power (not too sensitive, but not downright insensitive either like some planars), but rather they make flaws in the amp easier to spot... I can imagine that the sound card on a motehrboard may well have enough power but the implementation ist just not clean enough to please someone used to audio-targetted implementations.

That sums it up quite nicely. And touches on the clipping part as well, which, in my opinion, is often the reason why headphones sound bad when driven by a mobile phone with its really resource limited amp.

or

 

He-500

 

What is important to me are the following:

 

Comfort

Open wide sound

Smoothness

Airy-ness 

Deep Sub-bass

Excellent Mids

Detail and Separation of Instruments.

Accurate sound positioning

 

I use my headphones for everything: Movies, Music and gaming

 

I will also purchase either the Magni 2 or a Lyir.  My current Creative Titanium HD sounds fantastic which means no need for a DAC

 

thanks!!!!

I would like someone to have a good comparison of these 2 headphones as well. From my understanding though, the HE-500 will probably beat the K712 in all aspects but weights more than twice as much and not nearly as comfortable. I'm using pretty much the same setup as well, with Asus Essence STX II and Magni 1. So far I'm enjoying the K712 immensely, I really can't find any faults with them. I planned on buying them initially to try them out so I can decide to go for the $200 massdrop K7XX edition, but I'm enjoying these so much that might just keep these instead for $360 because I don't want to get the K7XX and it turns out that they're not the same. Plus the resale value for the K712 should be more anyway.

the problem is  getting too many conflicting reviews for both the he-500 and K712pro.   I'm leaning more toward the k712pro but I want it to be a substantial upgrade from my ath-ad900x.

well swifty7 frankly speaking if you are looking after a substantial upgrade over, then k712 pro is not the one for you in comparision to 900x.

 

Reason : The K712 might be expensive compared to AD900x more than double the price of it but doesnt hold in that regards meaning the price to value comparision especially when you compared it to a good headphones from AT like AD900x .

 

Remeber AT hp's have always been very good at MIds & Treble. AD900x mids & K712 mids are almost on par , it will be upto the user who likes more mids of which headphones .

Bass-wise ...AD900x is more punchier & tight & K712 are more fuller & deeper.

Treble - Ad900x has more sparkle to it , K712 is perfect but the added sparkle of at900x is also v.good due to which these headphones are more Airy.

Coming to resolution & clarity of sound this goes with a little to K712 but more than double the price is too much for it.

Soundstage : AD900x has clearly more soundstage ,Many say that it is artificial but it is nothing that artificial , it is better & people saying such thing because they want to hype their owned headphones more .Remember these hp's have such addiciting soundstage that when you move on to other headphones you really want that type of soundstage (being myslef an owner of Ad900 once), but I say that K712 soundstage isn't big like 900x but it still is fine that shall satisfy your tastes.

Comfort : Both are on par.

 

Now coming to He500 , will also include He400 :

 

See now these headphones really justify their price range , the first thing you will find in them is their outstanding clarity which is not reached by both 900x & k712.

i will keep it brief ... HE hp's lack soundstage though insturment spearation is great . Treble is better with AKGs & Mids of both are great , its just akg's are forward compared to Hifi's which causes many to call HE500/400 mids to be recessed or V-shaped.

But at resolution clarity detail retrival dynamics insturment spearation & bass , this is what He500/400 really outstand the others.

The bass is surprisingly strong and good with the K712.  Both the AD900x and K712 have improved bass for open air headphones that I've owned/used in the past.  AD900, HD650 and HD598.  The bass is as deep and pronounced as the HD650 but it has similar impact and strength as the AD900 did, so AD900x and K712 both win here.  AD900x still has that nice punch that AD900 had but stronger and fuller.  K712 while doesn't have quite the punch, I think it goes deeper and fuller.  It's a toss up, just depends on what I feel like listening to.

 

Mids/Vocals, easily AD900x wins here.  Female vocals are sublime with AD900x.  To me the K712 the mids and vocals are slightly recessed and female voices not as sweet.  But the sound is balanced.  AD900x slight win here.

 

Treble, K712 slight edge.  AD900x has more sparkle, more fun, but it can diffused at times and is the cause for hearing fatigue.  K712 rolls off more to me, it's softer similar to HD598.  HD650 still veiled to me.  K712 doesn't have hearing fatigue but treble is still detailed.  I would even say it's an issue of longer term comfort, so K712 has slight edge here, even though AD900x treble can bring up-lifting music to life more.

 

Soundstage, K712 slight edge here too.  AD900x soundstage is definitely larger, but it's feels artificial at times, which is why I think the treble can become diffused.  K712 the soundstage is smaller but it feels more natural and to me, sound separation is better.

 

Efficiency?  On my NFB-12, AD900x I use low gain at around 9 o clock.  K712 I use high gain at around 8-9 o clock.  Who wins here?  I dunno, you decide. 

 

I will not be selling the AD900x, I love them.  I'm enjoying the K712 too.

 

Comparing to K551, well K551 build quality trumps both.  Comfort nearly as good, cable horrible.  Sound wise it's understated and neutral but detailed.  It's good enough for when I'm in public and traveling.  That's all I'll say.

 

One thing would mention, between the 3, after I listen and allow my ears to acclimate to the sound, I can enjoy listening to any three.  AKG and Audio Technica made great headphones that my ears enjoy.  I hope my observations aren't too polarizing or varying, since I to me all three headphones reproduce sound very well comparatively to my speakers.  I don't find any particular sound or element to be way out of sort to distract or annoy me, other than the fatigue on the AD900x after a few hours.

Also this info from this thread only...

Hi guys, I hope you guys don't mind me posting this video on here. I have a K712 too and I find the Play It By Ear amp is an awesome pairing with the K712.

 

post #3718 of 3718

Live long and prosper to all Head-Fi members!

 

I joined to ask what do you guys think about MrSpeakers Mad Dog vs AKG K712. Both headphones are similar in price and measurements (MD vs K712).

 

Wasn't sure if I should start a new thread for this. I hope asking here is OK.

 

Cheers
