AKG K601 & K612 Pro Owners... UNITE!! - Page 65

post #961 of 2275

After two full days, I am very happy with my purchase. These are no slouch, whatsoever, and a steal for their price range.

Do you mean the actual cups, or the pads? I don't know about the others you mentioned, and I cannot guarantee that the K612 pads are exactly the same as the K601 pads (it's likely that they are), but the depth of a K601 pad is about 2.5cm. The total diameter is about 11.2cm, but the pads are curved on the edges, so at the fitting we're talking about 10.6cm. Inside diameter is about 6cm. Note that because of the foam rings that fit under the pads, the depth in the middle may be reduced by a few millimetres when the pads are fitted.

Yeah, I got my K601 patched up on the inside. I redid the other three connections while I was at it, though one or two not necessarily better than how it was originally. They don't wrap around the wire or anything before soldering (so mechanically the joints are only held by solder, which is usually a no-no), but I guess it's generally okay because of how the strain relief works on this set.

 

I pretty much killed the outer grill getting it off too. :o

Yup, the strain relief is provided by that little plastic nub at the end of the cable that locks in. A lot of the AKG line is done like this. I think yours is the first case that I've heard where it didn't hold! I'd double check to make sure it's pushed down all the way.

I meant the pads, not the cups. Some people call pads cups and I guess that got imprinted on my mind.

 

I no longer have the dt770 so I cannot measure them. x x

Oh, and I should ask, how big is the diameter and depth of the pads compared to the soundmagic hp100? (They look a lot like the dt770 but I don't know if they are the same diameter or not. So I'm kinda curious.)

Comparing the depth and inner diameter of the K612 pads and the stock velour DT 770 pads. They seem about the same to me with the K612 pads being a little deeper, there only seem to be a few mm difference between the two, the K612 does have foam over the driver which does reduce the depth a bit, so probably about the same in the end. The K612 pads have firmer foam in them and the outer diameter of the pads is larger. I cannot measure them properly because I don't have anything to measure them with at school.

The nub itself held admirably and was all the way in place. When I cracked it open and saw it, my reaction was pretty much "hm... wow, that makes sense."

 

What didn't hold was the ground wire to the left earpiece. It was about ready to snap at the solder joint of the wire to the headphone terminal connection inside the cup. Well, it's not so much of a joint per say as some bare wires "glued" in parallel with the terminal with solder, which is always a mechanically weak way of doing things. The gauge there is kind of thin, but I'd think it can afford to be with the strain relief as effective as it is. Except that apparently it didn't hold up for me somehow. I must admit to the headphone cable getting caught on things and a some accidental hard tugs over the years though, so I don't really fault AKG.

 

Yeah, I pushed the nub back in place once I was done resoldering the connections. I was going to do just the one that was bad, but in the process of trying to put the headphone back together I snapped another connection, so I figured I might as well redo them all. Clumsy hands, yep.

The nub does a pretty good job, but the nub only holds that outer wire. The inner leads can get pulled a bit, so if the tug was hard enough maybe it pulled on the lead?

 

AKG definitely has the most intricate earcup design. Definitely Austrian on the inside :D. Just don't take it apart and try to put it together again. It's incredibly intricate on the inside.

 

Anyway, glad they're up and running!

Just got my K612 pro today and I'm loving them already.

post #971 of 2275

Hi all, 

 

I haven't picked up a pair of reference or high quality cans in almost thirty years, however I am on the brink of buying some K612s.

I didn't want to start a new thread amongst the sea of 'which should I buy?,' so if you would please allow me to cover off a couple things before I take the plunge on this model.

 

I have whittled down my choices to K612, K171(I don't believe there's a real advantage to the 271?) or K240. [[Note I originally wanted K550 however they look too big]]

I particularly like the construction of the K171/271, because of the old school wire type frame, that has no gimmicks like stretch cords such as those found on K612 - which could snap at any time. 

 

The use of these is for recreational listening rock, classical, jaz/some recording and occasional film/gaming, through a DAC/sound card and possibly a mini amp if required(though to start would prefer unamped). I am pretty big on sound stage, but only in a natural sense if you understand.

 

They would be with velour pads.

 

My understanding was that open back phones would allow more sound stage because it doesn't crowd your hearing like closed back phones will. However in later development, models such as the K171/271 were of such a quality that they managed to avoid that claustrophobic side effect of closed cans while also having a more defined stage presence.

 

Is that fairly accurate?

 

 

 

- Is the naturally gained sound stage from K612 as open back, considerably more noticeable than the cleverly designed K171/271.

- Does the K612 have any specific advantages because it's a new product

 

My thinking is that if the sound stage on the K171/271 is spacious enough while still accurate, then I see no reason to use the K612. I don't expect it to be as good as the K550, but they are closed cans and they get high marks for sound stage - which gives me hope that the K171 would be sufficient.

 

This post makes it seem like I'm leaning towards the closed back more, and I suspect that's right, because I have this old habit of thinking closed back will ultimately provide the best sound reproduction - when done right.

 

 

Hope that makes sense thanks for reading - off to start searching for amps.

 

Thank you

I don't know why you think closed back 'will ultimately provide the best sound reproduction'. All the best headphones are open back.

post #973 of 2275

As I said, a bad habit - possibly from when I was younger and the only quality headphones I came in contact with were (as far as I remember) closed, or closed enough that I specifically remember that aspect of them.

 

 

This is why I specifically mentioned the 171/271 and the 550 as an example of closed back that benefit from modern technology - where they've seemingly managed to limit a lot of the boxed in feel of closed cans.

 

Having said that, I am really supportive of the K612, just not the build style. If the K171 was open backed, I think I'd pick that.

 

 

Maybe the simplest question is, has anyone had their K612 headband cords snap?

I used to agree with this but then I heard some fantastic closed-backs that simply blew me away and changed my opinion of what a closed or mostly closed headphone is capable of. There is a couple notable exceptions to the open-back being the best rule, I agree most of the best headphones are open-back, but oddly the very best to me was a closed-back. The bass-heavy R10 sits as the most natural and the best sounding headphone to my ears and many agree it's the best dynamic headphone ever made, the K812, HD 800, T1, etc just didn't compare to my ears, the R10 was a league above all of them. The Fostex TH900 competes very well with many of the top open-backs right now.

I own the K240 and K612 and I can assure you the K612 is the much better headphone. The K240 has a nasty treble spike and lacks subbass. I haven't heard of anyone having that issue before.

Thanks kman,

 

And considering you are open minded about the closed back, have you heard or know much on the K171? I like their physical design the best, but I question whether they would have the sound stage or the clarity that the K612 might. Also they come with some amenities, like detachable cord and etc.
