Product Description
We’ve partnered with Dan Clark Audio (formerly MrSpeakers) to improve a remarkable and well-regarded pair of planar open-back headphones. Introducing the Aeon Open X: our take on the Aeon Flow Open.

Dec 26, 2019
 Sound Foundations Our community had their eyes on another collaboration with Dan Clark soon after the launch of the acclaimed Ether CX. With the Ether CX being a true flagship worthy closed back headphone for our product line, we were also very excited to add to the sister series with the Aeon Open X. There’s always a chance...

Here is what Dan Clark had to say about some of the distinctions between the two products lines.
“ÆON Tone: ETHER CX has a more neutral voicing with a bump to the bass, while AEON has a bit more of a V to the response and is less linear and smooth sounding. ETHER CX has a bit more heft at the lowest frequencies, it just feels like there's more power at the sub-bass even though they measure similarly. AEON Closed presents a bit more upper bass energy due to the V-shape to the response. ETHER CX has a smoother blend to the midrange which delivers better phase coherence, while AEON has a bit of a peak in the 5K region, something we worked to eliminate in the ETHER CX, and a brighter than neutral top. Dynamics are very similar. Soundstage they are close, ETHER CX seems a trifle larger. Efficiency: ETHER CX is 2-3dB more efficient.”  The Aeon Flow Open is known to have a warmer tonal quality, a slight V shaped response, and a medium sized soundstage. We nudged the Aeon Open X to have similar qualities as the Ether CX, which has a rather neutral sound signature and wide soundstage for a closed back design. During the development process we explored the use of fenestration inside the earpads to open up the soundstage. This was done by initially using a soldering iron to melt holes into the interior of the earpad. We then used some electrical tape to cover portions of the openings allowing us to get a slightly wider soundstage. We fenestrated the surface of the ear pad that is most reflective towards the opening of the ear creating a wider and deeper soundstage.  Earpad Experiments
We also played with the acoustic dampening paper that covers the driver openings, adding just enough material over the drivers to find a nice middle ground which lifted the treble from 3 kHz to 6 kHz. Whereas, the Aeon Flow is more intimate and forward in its presentation. The Aeon Open X still captures the essence of the Aeon Flow line with its more relaxed and smooth presentation.  
  In creating the Aeon Open X, we tried to maintain the consistency of the Aeon Flow Open, as well as some of the airy and spacious qualities of the Ether CX.  The low end still retains that nice deep kick which should please fans of genres that call for low end punch and extension. All in all, this is a wonderful sounding headphone that will please many.

These went out of stock pretty early for a new headphone collab... will they be coming back? I wanted to pick up a pair eventually but didn't expect to end so soon else probably would've grabbed earlier :[ .

Check my review on them , its an emotional one , but to the point . I did not listen to CX , but heard it is about being punch shy or sort of , the Aeons X , on the opposite , is pretty punchy and dynamic . Amazing piece of audio art , i would call them .Comparing back and forth between them and M1060C open mod, Beyer DT250 and HD58X and 6XX , the Aeons X win soundwise and build .

Anyone know if these have the wave guides? There’s no flow in the name so I assume not! The price difference for the ether cx makes it worth while but These aren’t down enough from the real thing to make up for the downgrade!!

Will the chord mojo power them well?

When do they ship?
can these be a good side-grade to the focal elex? I love the hd6xx & consider the elex to be a upgrade/side grade, are these too similar to those two headphones? if so I’m wait for the Arya.. unless I should go to the Arya either way

Do these come with any warranty from Dan Clark, what if a driver goes out?

Would this work well with a Schitt Hel?
Sep 30, 2020
It should, there is the combo of Schiit hel, mic and aeon flow rt on Dan Clark for gaming

Are these an upgrade from the HD6XX? That's what I have now.
Oct 19, 2020
I have the 6XX and these and I would say it is definitely an upgrade. I still prefer the tuning of my 4XX over both sets but there's something spectacular about the Aeon.

From what I’ve read a lot of people think they are the same but they are not. The RT has 2-3 dB more bass iirc. I got mine about a week ago.
Sep 22, 2020
NO WAY! I had been waiting on this drop for so long I thought it would actually never come back. After I saw the Aeon RT was until supplies last, I assumed it was never coming back to drip again. My AFO RT came in 3 days ago and I am in love.
