Hi there!Thanks to Cee Tee for his perseverance, he stuck with us for a long time to make this happen, and I'm really excited for us to be doing our first drop!
We tried to make the ETHER CX a unique product, and there is a lot in that's new. For example, it uses the original ETHER C driver but with a new tuning system delivering a unique and smooth voicing with gently lifted bass, and a really smooth transition from bass to mids. The new hardware is also a bit lighter and with no moving, as per our AEON design, and it sports a new ear pad. I hope it's a lot of fun for those who opt in the drop.
If anyone has any questions for me, please chime in.
EDIT: To make the information easier for people to see, I'm copying two of my posts contrasting ETHER CX to ETHER C and to AEON Closed. The format of the two posts is a bit different in style as I was sort of answering two different questions, for the editorially minded. :-)
The original ETHER C had a tip toward the higher frequencies and also had some pad bounce that made bass a little unpredictable. With ETHER CX we have a new pad that reduces pad bounce for smoother and more impactful bass. By bringing the highs better into balance the whole headphone has warmer tone, without lacking air or shimmer, and the bass really pops on good source material (listening to Robag Wruhme's Wolluwe track as I write this and a lot of toe tapping going on).

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.
Comfort: The AEON is lighter and is a bit more comfortable for more extended listening.
Isolation: ETHER CX offers several dB more isolation.
The following chart is showing both headphones with no damping,orange is ECX and purple is AEON Closed, measured on a GRAS 45 CA with DF compensation. The main takeaway is the smoother response of the ETHER CX, with a less pronounced "V" to the response for better midrange-high coherence, yet with a fun bump to the bottom end. The smoother top end lets the mids and bass stand out nicely, too. I like to think of it as "audiophile fun" voicing.
