AKG K702 (The Classic) vs. K612 Pro (The Upstart) – Review and Comparison - Page 8

post #106 of 194
Brooko, you were curious about the K550. Breakin din't help much; they sounded perhaps a touch less strident on top, slightly less congested in the mid, and the bass was more fleshed out. Not a night and day difference. Having read a number of reviews that mention a slightly sweet tonal balance with powerful bass and relatively open mids, I heard none of that. My 550s sounded overly bright no matter what. I'm not excluding the chance of manufacturing variance.

Time to mod: I started out with dampening the back of the driver with closed-cell foam. Helped a bit. Then, I installed open-cell foam inside the pads (the same foam as included with Beyer pads). That helped immensely at the expense of top end air, but worth it to me. I also tried LCD2 pads with and without the open-cell foam. I kept the foam inside the pads for a more forgiving tonal balance. In essence, I truly do not like the 550, but given its application (used in conjunction with a uDAC2 in a portable setting) they'll do fine. On the basis of pure sound quality, I don't feel like they match or better any cans in my stable, other than the Sony V6.

I really wanted to like them. redface.gif

Thanks Schaff

 

Likes like I'll have to try them myself.  Appreciate your viewpoint and comments on them though.

 

I'll be back in the US late Feb - so will try and get to one of the larger NYC stores for a listen.

They do beat the MA900 in all aspects IMO, except for sheer soundstage size, but it definitely wins at imaging and separation there.

The angled pads I've ordered [K702] are amazingly comfortable, but they mess the sound a lot [essentially make the cans warmer... lol] like more bass and less mids/treble, worse imaging, slightly wider stage but the imaging really suffers...

The stock pads are really good regardless.

 

Of all my headphones, these have the most highs extension [good] which makes my preparations for the new HiFiMAN easier.

 

I'll be selling some of my headphones though... Not the K612 or the X1s, but the W1000X or MA900 might go...


Have you noticed the impressive bass-extension and sub-bass presence on the K612? I felt the K702 pads did mess with the imaging as well. I wonder how the non-angled Annie pads or K712 pads will be on them. I felt these are amazing for gaming and one of the best all-rounders I have come across.

Definitely.

Yes, both the bass and sub-bass extension is pretty good [neutral IMO, no roll-off, which is great]

The K612 can be a bit strident in the treble regions sometimes [in a sense that it doesn't smooth out sibilants] but overall a very neutral headphone, lacking just a bit of air to be perfect for me.

If you have an amp and 200 bucks to spare, its hard to not recommend it and for gaming its really amazing.

 

I am eyeing the new HiFiMANs though.

They're an even better deal in the UK - £120. That's cheaper than the ATH-M50 that everyone blindly recommends. Just under the K550 too.

Yeah I got them for around 160 euros so that's roughly the same as in the US/UK.
One of the few headphones where the price is equivalent after VAT.

I have noticed that as well, although I don't find it fatiguing about it, it just doesn't smooth or gloss them over. It's an excellent phone for the price.

I am curious about the new Hifimans, I found the current models impressive.

Me too. There is something about the planar sound that makes the music float by :]

I found the amount of air in the treble and vocals particularly impressive [with the HE-6].

So, naturally I am eyeing the 400 i or 560 :]

The ortho sound is interesting, the Hifiman and Audeze orthos are quite different though. I liked the He-500 and He-6 a lot, I wasn't the biggest fan of the HE-400 though. I am considering getting a better headphone in time or I may just stick with the K612 and get a good closed back(hoping the HD 380 does it for me) and call it quits. I do have an idea what I want though if I upgrade. I'm just bummed my ideal headphone is virtually unattainable and expensive.

Yeah, let's see... I'd take the K612 if it was a totally comfy headphone for me,

Unfortunately, I have rather big ears and 90% of my headphones end up touching a certain part of my right ear [god knows why they are not 100% identical].

The headphones that were uber comfy for me were the Fidelio X1s and HiFiMAN HE-6... Other than that, the headphone usually touches my ear. [angled pads do remedy that issue somewhat].

Said that, I don't have that much experience with different headphones and as long as the pad's depth is the same or bigger with the newer models, I'll be happy :]

 

As far as sound goes, if the 560 is a slightly warmer HE-6, I'd be happy. And we'll see how the 400i shapes as well :]

The K612 does do it for me in terms of comfort after break in, the pads on the K612 take forever to break in though. I do have big ears but thankfully they don't touch the driver anymore(my right ear did for the first month though causing a hot spot after a hour of two). The K712 was insanely comfortable but I didn't like it's sound quite as much. My ideal headphone is the bass heavy R10, I sort of regret listening to it as I can't forget that sound. I found most planars comfortable in terms of ear comfort but the weight does get to me especially on the Audeze's. Here's hoping on that, they reduced the weight on the new Hifimans as well, maybe I will consider them, have to wait on impressions.

Yep, I am waiting for impressions too. But I am planning to buy them as soon as they release. One of them anyway.

The K612s make it very easy to tell whether the recording is bright or dark. It's quite amazing actually.

I really enjoy most of my library with it, except for the really bright ones.

The M-Stage is great too, obviously.

For gaming, these are amazing too, the imaging is supreme and the rear/front positional cues are very easy to identify.

The K612 is one of the most neutral headphones I know of, it's neither dark or bright in the treble, and is pretty much a flat line down most of the frequency response, this makes it very transparent and sensitive to source and system changes. Other headphones do something similar but many achieve it by boosted treble to give the impression of transparency.

Got my K612 today, very happy so far :)
