the product names on this brand seems quite confusing to me. Can anyone clarify if the "Aeon 2" in red are the same as the "noire" but just in red, or if a different headphone altogether?

edit: meant "Aeon"

Suspect you mean the Aeon 2. The noire is the same base unit but obviously black paint but more importantly different pads that change the frequency response.

yes, sorry! I meant Aeon, haha. OK, so there IS a difference., and wow didn't know that pads could change the sound

Don't ask me which is which but one is semi perforated.

DCA pads are not cheap and have sticky rather than clip on to affix so wouldnt look to regularly swap pads. But if you got a bargain on either flavour you could convert to the other style in terms of sound quite easily.

Although in theory, the Aeon 2 once retrofitted with the Noire's Perforated pads should measure just like the Noire, oratory1990's measurements of all three configurations show that there's still a difference:

Seems like if one wants Harman ear gain, buying the Aeon 2 then changing the pads yourself is the way to go.
 
Hey guys! I had an issue with my left ear phone dropping in volume seemingly randomly at times. Often shaking the headphones a bit would somewhat fix the issue but not entirely. The warranty is almost expired so I thought what the heck I might as well try to fix it myself.

I'm happy to report that the headphones are extremely easy to service & repair. The inner construction is very simple. Just make sure to snap photos of every step and also make sure to use the right length screws and screw them in their right place and you're golden. The smaller inner ring screws hold the driver, the longer screws attach to the casing on the outer edges.

In terms of the actual issue I've noticed the two signal wires were twisted and very close to being in contact with each other. The wires that are soldered to the cable plug contacts don't have any insulating material (I mean at the solder point). I don't think that's unusual for most products. But if they were insulated I'd assume this problem wouldn't occur in the first place.

I've just placed some insulating duct tape between the contacts and it seems this resolved the issue. It might have also been a loose contact issue but it's hard to tell.

I've read reports online of other people experiencing similar issues with volume drops. Hope this helps anyone else that has an out of warranty pair and can't get it fixed by DCA for whatever reason.

Edit: Correction about insulating material, I meant at the solder point not the entire length of the wire.

Unless they were actually touching those rigid metal contacts sticking out the end of the hirose connector I don't think would move enough? They were probably twisted to keep slack from vibrating inside the cups. From what I gather from various sources including previously in this thread is that there were some batches of drivers prone to this exact kind of issue. Imbalance or volume drop that occurs intermittently. I think I've read about 5-10 cases so far online with those kinds of symptoms.

I would send them in for warranty if you can.

It's strange though because I no longer experience the issue. But previously I constantly had to adjust the right channel between -1 to -4db to center it.

Maybe the contacts weren't touching each other but instead it was just a weak contact? Anyway I'm happy that I no longer experience the issue.

It's been fairly intermittent for people. If the contacts were touching I'd suspect it would have been much worse of issue than off center but maybe. People seemed to be able to reset the issue with some loud playback only for it to resurface.

I would at minimum reach out to DCA with your findings while in warranty so that if it does reoccurr you'd have some history there to work with. These are not inexpensive.
 
As noted by Amir earlier in his comments the customer sent him the Aeon 2 Noire without the included tuning pads. As such, the review really only covered a subset of the system's performance options. It's important to note that the tuning system not only affects the frequency domain, but also THD performance. For most users using the tuning kit is recommended as the tuning of the top octaves may sound bright to those looking for a more neutral or more Harman response.

The following shows the effect of various filters on frequency response. For myself I generally use 1 notch white + 1 black as shown in the blue line. The reason the filters reduce the amplitude of the peaks and sometime valleys is they serve to reduce standing waves. Their ability to do so is limited, which led us to develop our Acoustic Metamaterial to give better control of all aspects of upper octave performance.

As is evident, the blue curve is significantly smoother than the no-pads tuning, and is also therefore easier to PEQ, using the following settings:

Last of all, as noted above the filters significantly reduce THD, including in the lower midrange. This particular unit I pulled from inventory also has a bit less bass THD, but Amir's unit was within norms. Note the reduction in THD around 700Hz.

I hope this provides additional insight into both the intended use of the product as well as the performance effects of the tuning system.
@Dan Clark

Using 1 black felt + 1 foam without EQ could bring similar results to black felt + 1notch white + EQ?
 
Had to warranty mine because of an imbalance on the left side.

Before warranty:

After Warranty:

Ended up much better after and the image sounds center as far as I can tell so far. A couple db difference maybe around 100hz but my measurement rig is basically a UMIK-1 mushed between the earpads.

Koss KPH40 for fun. It matches pretty good:

I got mine RMA'd last year from the thread and guess what? its happened again, this time on the left side, after my experience with how subjectivist and dragged out the RMA was with the local retailer I'm divided between doing it directly (more money sunk on this) vs Opening it up myself

I'm pretty sure it's the driver itself. I would reach out to DCA directly. Seems there is a batch of drivers causing them some problems.

Kinda sucks when its intermittent, sometimes it's real obvious sometimes it's not there.

FWIW, mine had and the rma are developing the same issue it seems, and it seems completely clean on the inside

I did reach out but it seems they've just ignored what I've asked and just asked me to get mine fixed, corporate response I guess

I don't understand what you mean. I've only ever dealt with Sue at Dan Clark for support. Don't think one could refer to them as corporate.
