Can you hear a high frequency noise in the left side? I have this noise in the left side but not in the right side. Just want to know if this is a common problem or just my pair. Thanks a lot!

 


Might be the recording, can you play it in mono or reverse the channels going to the amp/phones?

I hope it is not something serious like a damaged driver, and it is just that one instance being too bassy.

Mine just arrived new in the mail today, and the left cup sounds like a plastic shaker egg, meaning I can literally shake it and hear broken bits of stuff rattling around inside.

Does the K712 have a sort of pivot joint that you can move the top of the cups in and out so that you have even pressure from the top of the cup to the bottom like the K812?

yep, also the wire headband that gives the whole thing structure is very flexible, they're the most comfortable headphones I've ever worn.

I hear it in both left and right ears, tested by listening one at a time. Nice catch for you, but sinewavesounds.co.uk needs to step their game up because there are a ton of noises besides a 60hz hum in that clip!

I just joined to post my issue as well. My also has that rattling high-freq sound as well, but in the right ear cup. It's caused me soo many annoyances, becuase I listen to music like Nujabe's and I can sometimes hear it. Or when I play FPS games and there's low bass sounding explosions it also becomes noticeable. I'm going to send these back to Amazon and get another pair, in the "hopes" that it won't have this issue.

 

Really can't deal with how annoying it sounds when exposed to those bass sounds = /

Also that 60hz bass test, REALLY makes it obvious lol.

Any advice on how to contact Hector Hernandez from the AKG service department without sending numerous emails and messages? I attempted to contact him via email & phone on Friday with no luck so far.

How does akg k712 fares up against he400 .heard he400 has the cleanest sound in this price range and also the instrument separation is best though having small soundstage???
post #3261 of 3450
The soundstage is not small on the 400. That's just so false on so many ways. First of all, the 400 is better depth in the soundstage and amazing imaging unlike many, many dynamics out there that spread out more to the sides and not so much out front and back. Second, the 400's soundstage is more rounded/circular, meaning more natural.

It's a decent soundstage. Not immediately amazing, and not congested and restrictive.
post #3262 of 3450
Small meaning in comparison to some other.. Like i also own ad700 which is not just wide but it's good in height too and it also has a good depth when running through fiio e17,compare to it he400 has only good depth but it just can't stand when compared in height and width ,the same reflects in gaming as i also use them primarily and mostly for gaming.

You're comparing the HE400 with a headphone that is basically unrivaled by anything but AKG 70x and HD800s in terms of soundstage. Pretty much EVERYTHING lacks in soundstage compared to the AD700. That will almost always tend to happen when you have a very open, dry, bright, bass light headphone.

I did a comparison of the AKG K712 vs the Beyer DT 150, this was a really hard choice on which I thought was better. While I do slightly prefer the DT 150 overall for a couple reasons and the fact I get a little more use out of it, it's a pretty much too close to call for me. One day I will prefer one over the other.

You are Right Mad Lust. Also I did a comparision of hours on specfically Bioshock for Soundstage for both He400 & Ad700. Surely the 700 is bigger in terms of wideness & height but it does'nt stand aginst the depth provided by He400. He400's depth is actually hard to point out initially due to less or almost no airyness but as you said the back/forth imaging of it is beautiful. Also He400 soundstage is much more Accurate & unexpectedly sound's actual directionality with their distance is completely perfect on He400 rather than Ad700 where sound is much more in your face though due to airyness many a time directionality is easy to percieve but the actual distance of diff. sounds & from where they are coming was much much better & true on he400. Am happy with the overall perfomance of he400 in this case though their overall soundstage may be less .Also using xonar dx as DAC it increases a bit . Hopefully I think Vali/Asgard may help it a bit more in terms of Soundstaging than Fiio-E17& also heard bifrost improves it a lot though dont know how much in comaprision to Xonar dx.

Still on the fence with my new K712s, they’re competing with the HD700s :smile:, but I managed this last week to sell off my K701s w bass port mod, K501s, K240DFs, Senn HD580/600, and the Grado SR325is as I‘ve found IMHO the HD700s after 8 mths made them redundant in my collection, so now I'm down to just the 712s and the HD700s.

 

The next step was to make up a new cable for the AKGs as I really hate multiple connections. I’ll live with the mini XLR for now, (no need to do major surgery to get them balanced until I’m sure they’re here to stay), but the mini 1/8 to 1/4” had to go.  From experience multiple connections do affect electrical transference, highs could take on a bit of harshness and bass looses tautness so for now I’ve made up 5’ of Canare 4E6S 1205, the 1205 being a bit more supple than the 4E6S 605, 705 etc, the 4E6S is 4 wires plus ground so I allocated a pair to each side with the common braided ground, still a bit stiff but manageable.

 

Sound difference, I’ll let you know in a few days as the placebo effect is not to be dismissed.

But a revisit to Shriekback’s “Care’  from 1983, a great album for checking sibilance and bass extension and attack, with the stock cable there was a slight blurring of the higher frequencies with increased sibilance, that now appears to be improved which also helps image focus and depth by adding a bit more air to the otherwise 712s darker/warmer presentation. Bass also appears to be better defined having a tighter presence and delivery with less bloat, undefined upper bass has a habit of hanging around the ears and not placed properly in the sound field which the HD700s do extremely well, again these observations can be placebo kicking in, only long term listening will tell but overall I find myself grabbing for the HD700s less often.

 

Should note that the Shanling PH100 sitting atop the Bryston BHA-1 is a nice affordable class “A” amp with plenty of power that did justice, especially with the bass with all my the AKGs including the K501s and 240DFs.

I returned my original ones (broken piece of something floating around in left earcup) and ordered more from Amazon. This time the right ear cup buzzed when there is any bass. Very Frusturating. I guess I'm going to start looking at other options

Just to give an update. After using these for a while, I can safely say you are right on your assumptions, and might just be it for me now. I've been using these constantly, and I have to say, I absolutely love these for movies. Gaming is also fantastic, considering I don't really play FPS, but it does the combination of soundstage and defined bass so well for me to enjoy them for non-competitive gaming. Considering my usage, I'll be sticking with these for now (something I didn't expect to do back then)

Well, I am extremely confused after mining this thread and the Q701 thread. For Jazz and Classical, which would you guys recommend (out of the K712 Pro, the 65th Anniversary, or the Q701), considering that price is not a factor in the comparison between these three?

 

Thank you very much in advance!

The K712 for at least the comfort! You do not want to experience the soreness that can result from AKG's bumped headbands on the prior K7xx models.
