So, I didn't notice a difference between the cables. I switched between the two cables on my magni/modi stack and they both sounded exactly alike. 

 

While the cable may look flimsy I've been using it daily for about four months. I walk probably 3+ miles a day (no car in NYC) in whatever weather the world throws at me, the cable still works perfect. It does look a little worn around the edges where it plugs into the source, but it hasn't affected performance and I think it's just normal daily wear.

I have disassembled HD570's cable. It's almost 3mm thick with insulation, and the insulation is around 0.5 mm thick. Then each OFC wire is 0.4mm thick. The cable is 3 meter long. Technically this cable is more than needed for the HD570's, which are 64 Ohm.

The Momentum cable is thinner and it's around 2mm thick including insulation. If the insulation is same thickness (around 0.5mm), then wires are most likely around 0.2-0.3mm, which is on the boundary of what 18 Ohm Momentum need from 1.5 meter cable.

Anyway there is other problem. The cable maybe is reliable in sense that it still plays stereo, but because it's 3 wires twisted tightly together in a single insulation following problems arise:
- crosstalk, which will rather significantly (depending on what is for you significant) decrease soundstage, and
- possibility of short circuits, and thus changed resistance between left and right that will affect middle point

The first problem is less of an issue, but second unfortunately is something you'd rather avoid.

A twisted pair that I have mentioned has this advantage, that every single wire has it's own insulation, and then there is second advantage if you make two twisted pairs, then each channel will be ground twisted with signal wire, and this will reduce electromagnetic influence between left and right. Note that if you have two signal wires very close to each other (only thin layer of paint is a distance) there will be very strong electromagnetic interaction. The article you mentioned does not mention that, because in that article they look at loudspeakers cables, and it is obvious there, that left and right speaker have separate signal-ground pairs in two separate cables. With headphones there is a problem, because both channels are usually transported in the same "cable". So best would be to have two separate twisted pair cables, which I am going to prepare, and see how good that is smily_headphones1.gif (Already bought all that is needed).

This question might have been asked already, but it's tough to sift through 150 pages. Are there any replacement pads that work for these?

post #2330 of 3361

@koolas You do know that some headphone amps specifically add crosstalk circuits to enhance the feeling of space, intended to simulate what speakers do by their very nature (i.e. spewing waves into a shared airspace between both speakers and both of your ears)? I don't see the minimal crosstalk that could possibly happen in a normal cable as a problem...

 

Nevertheless twist away -- twisted cables at least exhibit more favorable impedance curves.

Yeah, I'd be interested as well, but only brown are available... here:

Don't you think you would prefer to have a full control over crossfeed and to have it done digital rather than randon physical?

Glad to see the Audio cable is so cheap. I just killed mine.

Mic cable is ridiculously overpriced though.
post #2333 of 3361

The question I was wondering is if there are any larger pads that fit on the Momentum like Beyers or something. Anybody know?

post #2334 of 3361

I just can't decide if these are comfortable or not.  I don't have a lot of experience with over-the-ear phones so it's a little hard to distinguish sizing issues from the newness of having something over my ears.....

 

I think slightly larger earpads would make these much more comfortable.  (I have slightly below average size ears).

 

Sonically wonderful though :).  Treble isn't quite as sparkly as my IE8's, but it's an improvement in every other regard.

I'm starting to like these more than my LCD-2s.blink.gif The 2s obviously have an edge in refinement and sound more neutral, but the Momentum just makes my juices flow more. More oomph to the sound and less fatigue with less than stellar recordings, while at the same time not sacrificing too much in refinement and smoothness compared to the Audeze. I tend to use these more nowadays, and I switch to the Audeze when I'm in the mood for a more analytical listen.

As much as I like the LCD2 sound, the comfort is killing me. I cannot get pass half an hour mark without feeling nausea due to the clamping force and weight.
The Momemtum on the other hand is very comfy, though not as comfy as HD800 😝
I have quite a large head that even HD650 clamping force is also too much for me to bear, but not the Momentum

I have LCD-3 pads on my LCD-2, so pressure on the sides of my head is no issue. However, the headband causes discomfort on top of my head after about half an hour like you, due to the weight. 

The HD 800 had the same problem for me, though to a lesser extent. Headband pressure on top of the head due to weight :(

There is likely more EMI-related crosstalk present in most amps than from a short stretch of cable, but having a common separate ground pairing is not a bad Idea to help with stability. It might be wise to go one step further and re-cable for fully balanced, if you have equipment that supports it.


Has anyone taken that courageous leap? I'd love to know if it managed to improve the highs.

You know that thread don't you?

I won't be going balanced yet, cause my DAC/Amp is single-ended. Could look for new DAC, but this is another story:)

The plug you can buy in shop won't fit into Momentum's socket, so it's not possible to do anything without actually disassembling them completely and voiding 2yr warranty.

Also, I've noticed that Momentum's impedance curve is actually horizontal line at 18 Ohm, so cable as long is it's not broken will not matter. I'm more concerned about iPod cable, with that pilot thing in the middle of it.

I have noticed that my Roland RH-A30 has same type of earpad mounts - kind of a rubber around the earpad.
I could try using them on Momentums, and see how it sounds, but I'm quite afraid of damaging them, because they are very delicate.
You can provably try the ATH-M50 earpads.
